Roman calendar

The Roman calendar changed its form several times in the time between the foundation of Rome and the fall of the Roman Empire. This article generally discusses the early Roman or 'pre-Julian' calendars. The calendar used after 46 BC is discussed under the Julian calendar. Julian calendar and Sextilis, and allows for the insertion of an intercalary lunar month.]]

History of the Calendar

To begin with it was a lunar calendar containing ten months, starting at the vernal equinox, traditionally invented by Romulus, the founder of Rome about 753 BC. However it seems to have been based on the Greek lunar calendar. The months at this time were
- Martius (31 days)
- Aprilis (30 days)
- Maius (31 days)
- Junius (30 days)
- Quintilis (31 days)
- Sextilis (30 days)
- September (30 days)
- October (31 days)
- November (30 days) and
- December (30 days) Thus the calendar year lasted 304 days and there were about 61 days of winter that did not fall within the calendar. The first reform of the calendar was attributed to Numa Pompilius, the second of the seven traditional Kings of Rome. He is said to have reduced the 30-day months to 29 days and to have added January (29 days) and February (28 days) to the end of the calendar around 713 BC, and thus brought the length of the calendar year up to 355 days:
- Martius (31 days)
- Aprilis (29 days)
- Maius (31 days)
- Iunius (29 days)
- Quintilis (31 days)
- Sextilis (29 days)
- September (29 days)
- October (31 days)
- November (29 days)
- December (29 days)
- Ianuarius (29 days)
- Februarius (28 days) In order to keep the calendar year roughly aligned with the solar year, a leap month of 27 days, the Mensis Intercalaris, sometimes also known as Mercedonius or Mercedinus, was added from time to time at the end of February, which was shortened to 23 or 24 days. The resulting year was either 377 or 378 days long. The decision to insert the intercalary month, and its placement, was the responsibility of the pontifex maximus. On average, this happened roughly in alternate years. The system of aligning the year through intercalary months broke down at least twice. The first time was during and after the Second Punic War. It led to the reform of the Lex Acilia in 191 BC. The details of this reform are unclear, but it appears to have successfully regulated intercalation for over a century. The second breakdown was in the middle of the first century BC. This breakdown may have been related to the increasingly chaotic and adversarial nature of Roman politics at the time. The position of pontifex maximus was not a full-time job; it was held by a member of the Roman elite, who would almost invariably be involved in the machinations of Roman politics. Because a Roman calendar year defined the term of office of elected Roman magistrates, a pontifex maximus would have reason to lengthen a year in which he or his allies were in power, or to not lengthen a year in which his political opponents held office. It was only after Julius Caesar, who had been pontifex maximus for some years, seized absolute power that the calendar was overhauled, with the result being the Julian calendar.

Months

The Romans had special names for 3 specific days in each month. The system was originally based on phases of the Moon (Luna), and these days were probably declared when the lunar conditions were right. After the reforms of Numa Pompilius, they occurred on fixed days.
- Kalends - first day of the month, from which the word "calendar" is derived. Interest on debt was due on Kalends.
- Nones – depending on the month, could be the 5th or the 7th day; traditionally the day of the Half Moon
- Ides – depending on the month, could be the 13th or the 15th day; traditionally the day of the Full Moon :Months with Ides and Nones occurring on the 13th/5th day: January, February, April, June, August, September, November, December :Months with Ides and Nones occurring on the 15th/7th day: March, May, July, October -- :a mnemonic: ::In March, July, October, May ::The IDES fall on the fifteenth day; ::The NONES the seventh; but all besides ::Have two days less for Nones and Ides. Days were numbered in a way that is quite different from the modern Western calendar. The Romans did not count the days of the month retrospectively, looking back to the first of the month (that is: 1st, 2nd day since the start of the month, 3rd day since the start of the month). They counted forward to their named days. Also, to the distress of moderns trying to work out dates in Roman calendar documents, they counted inclusively, so that 2 September is considered 4 days before 5 September, rather than 3 days before.

The example of September

The following example spells out how days were named for the pre-Julian September, which had only 29 days. It shows the Roman form of the date, the translation, and how we would say it today. The Romans used abbreviations: "a.d." = "ante diem" = "day before", "prid." = "pridie" = "the day before", "Kal" = "Kalends" etc. :Kal. Sept. = Kalends of September = 1 September :a.d. IV Non. Sept. = 4 days before the Nones of September = 2 September :a.d. III Non. Sept. = 3 days before the Nones of September = 3 September :prid. Non. Sept. = the day before the Nones of September = 4 September :Non. Sept. = Nones of September = 5 September :a.d. VIII Id. Sept. = 8 days before the Ides of September = 6 September :a.d. VII Id. Sept. = 7 days before the Ides of September = 7 September and so on till :a.d. III Id. Sept. = 3 days before the Ides of September = 11 September :prid. Id. Sept. = the day before the Ides of September = 12 September :Id. Sept. = Ides of September = 13 September :a.d. XVII Kal. Oct. = 17 days before the Kalends of October = 14 September :a.d. XVI Kal. Oct. = 16 days before the Kalends of October = 15 September and so on till :a.d. III Kal. Oct. = 3 days before the Kalends of October = 28 September :prid. Kal. Oct. = the day before the Kalends of October = 29 September :Kal. Oct. = Kalends of October = 1 October Notice that by counting inclusively and by having a special name for the day before a named day the Roman calendar loses the possibility of saying: 2 days before a named day. Also, after the Ides, the date no longer mentions September, but is counting down towards October. When Julius Caesar added a day to September, he didn't add it to the end of the month. Rather, the new day that got added was the day after the Ides: :a.d. XVIII Kal. Oct. = 18 days before the Kalends of October = 14 September As a result, the position of all the following dates in September got bumped up by one day. This has some unexpected effects. For example, the emperor Augustus was born on 23 September 63 BC. In the pre-Julian calendar this is 8 days before the Kalends of October (or, in Roman style, a.d. VIII Kal. Oct.), but in the Julian calendar it is 9 days (a.d. IX Kal. Oct.). Because of this ambiguity, in some parts of the Empire his birthday was celebrated on both dates, i.e. (for us) on both 23 and 24 September.

Days of the week

The Roman Republic, like the Etruscans, used a "market week" of eight days, marked as A to H in the calendar. A market was held on the eighth day. For the Romans, who counted inclusively, this was every ninth day, hence the market became called "nundinae". Since the length of the year was not a multiple of 8 days, the letter for the market day (known as a "nundinal letter") changed every year. For example, if the current letter for market days was A and the year was 355 days long, then the letter for the next year would be F. The market cycle was a fundamental rhythm of daily life, and the market day was the day that country people would come to the city. For this reason, a law was passed in 287 BC (the Lex Hortensia) that forbade the holding of meetings of the comitia (for example to hold elections) on market days, but permitted the holding of legal actions. In the late republic, a superstition arose that it was unlucky to start the year with a market day (i.e. for the market day to fall on 1 January, with a letter A), and the pontiffs, who regulated the calendar, took steps to avoid it. Because the market cycle was absolutely fixed at 8 days under the Republic, information about the dates of market days is one of the most important tools we have for working out the Julian equivalent of a Roman date in the pre-Julian calendar. In the early Empire, the Roman market day was occasionally changed. The details of this are not clear, but one likely explanation is that it would be moved by one day if it fell on the same day as the festival of Regifugium, an event that could occur every other Julian leap year. When this happened the market day would be moved to the next day, which was the bissextile (leap) day. The modern seven-day week came into use during the early imperial period, after the Julian calendar came into effect, apparently stimulated by immigration from the Roman East. For a while it coexisted alongside the old 8-day nundinal cycle, and fasti are known which show both cycles. It was finally given official status by Constantine in 321. The days of the week were dedicated to the seven planets. They were (note the similarities of some of the days with French and Spanish and other Romance languages):
- Sunday – Dies Solis (day of the sun)
- Monday – Dies Lunae (day of the moon)
- Tuesday – Dies Martis (day of Mars)
- Wednesday – Dies Mercuri (day of Mercury)
- Thursday – Dies Iovis (day of Jupiter)
- Friday – Dies Veneris (day of Venus)
- Saturday – Dies Saturni (day of Saturn)

Character of the Day

An aspect of the Roman calendar that is quite unfamiliar to us is that each day had a "character", which was marked in the fasti. The most important of these were dies fasti, marked by an F, on which legal matters could normally be heard, dies nefasti, marked by an N, on which they could not, and dies comitiales, marked by a C, on which meetings of the public assemblies known as comitia were permitted, subject to other constraints such as the Lex Hortensia. A few days had a different character, e.g. EN (endotercissus or perhaps endoitio exitio nefas), a day in which legal actions were permitted on half of the day only, and NP, which were public holidays.

Years

In the Roman Republic, the years were not counted. Instead they were named after the consuls who were in power at the beginning of the year (see List of Republican Roman Consuls). For example, 205 BC was The year of the consulship of Publius Cornelius Scipio Africanus and Publius Licinius Crassus. However, in the later Republic, historians and scholars began to count years from the founding of the city of Rome. Different scholars used different dates for this event. The date most widely used today is that calculated by Varro, 753 BC, but other systems varied by up to several decades. Dates given by this method are numbered ab urbe condita (meaning after the founding of the city, and abbreviated AUC). When reading ancient works using AUC dates, care must be taken to determine the epoch used by the author before translating the date into a Julian year. The first day of the consular term, which was effectively the first day of the year, changed several times during Roman history. It became 1 January in 153 BC. Before then it was 15 March. Earlier changes are a little less certain. There is good reason to believe it was 1 May for most of the third century BC, till 222 BC. Livy mentions consulates starting on 1 July before then, and arguments exist for other dates at earlier times.

Converting Pre-Julian Dates

Finding the Julian equivalent of a Roman date can be quite tricky. Even early Julian dates, before the leap year cycle was stabilised, are not quite what they appear to be. For example, it is well known that Julius Caesar was assassinated on the Ides of March in 44 BC, and this is usually converted to 15 March 44 BC. While he was indeed assassinated on the 15th day of the Roman month Martius, the equivalent date on the modern Julian calendar is probably 14 March 44 BC. Finding the exact Julian equivalent of a pre-Julian date is much harder. Since we have an essentially complete list of the consuls, it is not difficult to find the Julian year that generally corresponds to a pre-Julian year. However, our sources very rarely tell us which years were regular, which were intercalary, and how long an intercalary year was. For this reason, pre-Julian dates can be very misleading. We do have a number of clues to help us. First, we know when the Julian calendar began, although there is some argument about it. We have detailed sources for the previous decade or so, mostly in the letters and speeches of Cicero. Combining these with what we know about how the calendar worked, especially the nundinal cycle, we can accurately convert Roman dates after 58 BC. Also, the histories of Livy give us exact Roman dates for two eclipses in 190 BC and 168 BC, and we have a few loose synchronisms to dates in other calendars which help to give rough (and sometimes exact) solutions for the intervening period. Before 190 BC the alignment between the Roman and Julian years is determined by clues such as the dates of harvests mentioned in the sources. This allows us to estimate approximate Julian equivalents of Roman dates back to the start of the First Punic War in 264 BC. However, the number of years before 45 BC for which we can accurately and precisely convert Roman dates to Julian dates is very small.

Founding of Rome

The founding of Rome is reported by many legends, which in recent times are beginning to be supplemented by more scientific reconstructions. Rome myth: the wolf is tearing apart a Union Jack to encourage Italians to buy war bonds]] Virgil's Aeneid, while not definitive, is an important source for information about those early times or, at least, the then-official versions of many historical events.

Latium and central Italy

In the age between the 10th and 8th centuries BC, the main population of central Italy consisted of two main groups of Italic people, the Osco-Umbri and Latins. Latium Vetus (the ancient territory of Latium) was populated by the non-Latin Etruscans, and the Volscians, Sabines, Aequi, Rutuli, and Ausonians. These people migrated from different areas of Italy, including current Tuscany, Marches, and groups came from Liguria. Among them, the Latins developed an organized society, which was the main source of the people who settled Rome. The Latins originally stayed in Colli Albani (the Alban hills, modern Castelli – 20 to 50 miles, or 30 to 80 km, southeast of the Capitoline hill); later, they moved down towards the valleys, which provided better land for animal breeding and agriculture. The area around the Tiber river was particularly advantageous and also offered notable strategic resources, as the river was a natural border on one side, while the hills could provide a safe defensive position on the other side. This position would also have enabled the Latins to control the river (and eventual commercial or military traffic on it), from the natural observation point at Isola Tiberina (the island in front of modern Trastevere). Moreover, road traffic could be controlled, since Rome was at the intersection of the principal roads to the sea coming from Sabine (in the northeast) and Etruria (to the northwest). The development of the town is presumed to have started from the development of separate small villages, located on top of hills, which joined together to form Rome. Although recent studies suggest that the Quirinal hill was very important in ancient times, the first hill to be inhabited seems to have been the Palatine (therefore confirming the legend), which is also at the center of ancient Rome. Its three peaks, minor hills (Palatium, Cermalus or Germalus, and Velia) united with the three peaks of Esquiline (Oppius, Cispius and Fagutal), and then villages on the Caelian hill and Suburra (between current Rione Monti and Oppius hill) joined them. These hills had expressive names: Caelian was called Querquetulanus, because of oaks (quercus), while Fagutal revealed its beech-woods. Recent discoveries reveal that Germalus, on the northern part of Palatinum, was the site of a village (dated to the 9th century BC) with circular or elliptic dwellings. It was protected by a clay wall (perhaps reinforced with wood), and it is likely that this is where Rome was really founded. The territory of this federation was surrounded by a sacred border called Pomerium, which enclosed the so-called Roma Quadrata (Square Rome). This would have been extended with the inclusion of the Capitoline hill and Isola Tiberina at the time that Rome became an oppidum, a fortified town. Esquiline still was a satellite village that would be included at the time of the Servian expansions of Rome. Celebrations for Septimontium (literally "of the seven hills"), on December 11, were in the past considered related to the foundation. However, as April 21 is the only datum for foundation upon which all the legends agree, it has been recently argued that Septimontium was likely to have actually celebrated the first federations among Roman hills: a similar federation was, in fact, celebrated by Latins at Cave (a village southeast of Rome) or at Monte Cavo (in Castelli).

The legend

The legend about the foundation of Rome obviously tends to relate the town to some of the most eminent entities of its age, in order to "demonstrate" that the great success of the town depends also on this special origin, or simply to complete a successful reputation with first-class references. It is, however, a complete story, and the entire Roman tradition is based on it. There are several versions of this legend; the version below is commonly considered the main one.

Aeneas and Julus

April 21 The defeated army of Troy crossed the Mediterranean Sea on the orders of prince Aeneas, to reach Latium's coasts. Here they landed in an area that is likely between current Anzio and Fiumicino, southwest of Rome. Most commonly it is supposed they landed at Laurentum (or Larentum); other versions say that they landed at Lavinium, a place named for Latinus' daughter Lavinia. Latinus, the wise king of the Latins, hosted them and let them reorganize their life in Latium. Lavinia had been promised to Turnus, king of the Rutuli, but Latinus preferred to offer her to Aeneas; Turnus consequently declared war on Aeneas, resulting in Turnus' death and the capture of his people. Ascanius, the son of Aeneas, also known as Iulus, founded Albalonga and was the first in a long series of kings. King Procas was the father of Numitor and Amulius. At Procas' death, Numitor became king of Albalonga, but Amulius captured him and sent him to prison; he also forced Rea Silvia (Numitor's daughter) to become a priestess of the Vestan cult. For many years Amulius was then the king.

Gods and priestesses

The legend of Rome's origin would have been much less interesting if the gods had had no role in it. Mars (who will always be the most important god for Romans) had two sons with Rea Silvia, a priestess devoted to the sacred cult of Vesta. (The name Rea Silvia (often written Rhea Silvia) suggests a minor deity, a demi-goddess of forests. Silva means woods or forest, and rea may be related to res and regum.)

Romulus and Remus

By this birth Rea Silvia had, as a priestess, severely offended both Vesta and the common customs of the time. Therefore Amulius ordered a servant to kill the newborn twins Romulus and Remus. The servant, lacking the stomach for the deed, put them in a bag that he left in the Tiber, to be carried away and drowned. The twin brothers were transported by the river and washed up on the shore in a place that, curiously, the legends don't specify. Here they were saved by a female wolf who nursed them (this wolf, Lupa, is still now one of main symbols of Rome). Romulus and Remus Nearby, in a poor dwelling, lived an old shepherd Eldon and his wife Acca Larentia. The shepherd found the babies, brought them home, and adopted them. When they had grown to adulthood, the brothers were informed of their history, so they went back to Albalonga, killed Amulius, and freed their grandfather Numitor. Romulus and Remus started planning a new town in the same place in which they had been found by Lupa. They decided that one of them would build a town and the other would help. So they went questioning the gods, asking for signs (presumably from the flight patterns of birds) that would tell them who should lead. Another version of the tale says that they had a competition to be won by the brother who saw more birds (or more birds of some species). Romulus went to the top of Palatine Hill, Remus to the top of Aventine. Romulus became convinced that he had been selected by the gods, or that he had seen more birds, so he casually threw his lance on the hill to find the place; when in the ground, the lance (which was wooden) immediately became the corniolus, a sacred tree in Rome. With the help of a white cow and a white bull, he then used his plough to trace the square borders of his town, following the traditional Etruscan ceremony. Remus outrageously crossed this line, invading Romulus's area and happily saying, "Can you see how easy it is?" Romulus killed him with one blow of his sword, declaring that everyone who dared to offend Rome would pay with his life. Romulus was the first ruler of Rome, and reigned until he disappeared during a storm, carried off by his father Mars.

Evolution of the legend

While the main body of the legend had remained more or less the same since its creation, some details were changed, mainly in order to put together the (slightly) different versions and correcting several points in terms of time and geography. The local ancient legends, too, were little by little brought into harmony with the main story. The effect of these interventions on the legend is quite evident. One of the earliest versions (5th century BC) is by the Mitilene Greek Ellanicus, and is usually reported together with the version by Damastes from Sigeo. In this version the founder of the village was Aeneas (in a minor version Ascanius (Iulus)). These versions survived until 509 BC (the year in which it is presumed the Roman republic started), when it was realised that, since there had been seven Roman kings and Romulus was the first of them, there was a gap between the 8th century of the first kings and the 12th century BC (the supposed date of the destruction of Troy). So as Romulus could not be the son of Iulus, he became only a distant descendant. The time between Iulus and Romulus was "filled" with the series of Albalonga's kings. Aeneas would have landed on Latium's coast during the reign of Latinus (king of the Latins), in order to find a compromise with local legends. Mars then had to be added in order to honour him, so Romulus became a descendant of Mars on his father's side, while mother Rea Silvia was connected with Aeneas via the Albalonga dynasty. The condemnation of Rea Silvia's sons is only one among the many recollections of the divine laws, of the religion that so deeply entered Roman life. Every group of people living in the area had its own similar legends:
- The Italics: among the Italics, like the tale in Hesiod's Theogony, the two brothers Agrius and Latinus were the sons of Telegonus, who was the son of Ulysses and Circe the witch (to whom is dedicated a mountain, Mount Circeo, in southern Latium where her cavern was supposed to be and where a cult was celebrated in her honour).
- The Latins: Saturn had been replaced by his son Jove, so he came down to the Earth and mixed with the Latins. After a while (maybe centuries), Evandrus came to Latium via Arcadia, and then Hercules came to free these lands from the menace of the giant Cacus. Finally Aeneas arrived from Troy, after tremendous risky adventures, and founded Rome. Notably in this version the Latins were not created or otherwise specially assisted by the gods, only the town was founded by Aeneas in the presence of these "authorities".

The date of the founding of Rome

During the Roman republic, several dates were given for the founding of the city, all in the interval between 758 BC and 728 BC. Finally, under the Roman empire the date suggested by Marcus Terentius Varro (753 BC) was agreed upon, but in Fasti Capitolini the year given was 752. Curiously, while the years varied, all versions agreed that the city was founded on April 21, a holiday dedicated to the sacred cult of Pales, goddess of shepherds; in her honour, Rome celebrated the Parritta (or Palilia). (It is to be noted, however, that the Roman Ab Urbe Condita (or a.u.c.) calendar begins with Varro's dating of 753 BC.) In the modern period debate has raged over the validity of the stories of Rome's foundation. Scholars have supported both extremisits - nihilists who want to believe nothing of the legend, and those who want to believe the legend wholeheartedly without skepticism. Archaeology offers the best chance of sorting out the debate, and indeed recent discoveries on the Palatine Hill in Rome have offered some tantalizing pieces of evidence. Chief among these is a series of fortification walls on the north slope of the Palatine Hill that can be dated to the middle of the 8th century B.C., precisely the time when legend says Romulus plowed a furrow (sulcus) around the Palatine in order to mark the boundary of his new city. The remains of the wall, and other evidence, has been discovered by the excavations of Andrea Carandini.

The name of Rome

The name of the town is generally considered to refer to Romulus, but there are other hypotheses. Some have suggested an Etruscan word, "rhome", meaning "hard". Another one of them refers it to Roma, who should have been the daughter of Aeneas or Evandrus. Current studies seem to prefer a provenance from an Indo-European root meaning "river"; Rome would then mean "the town on the river". The Basque scholar Manuel de Larramendi thought that the origin was the Basque word orma (modern Basque horma), "wall". Rome is also the Urbs, and this name (that in later Latin generically meant any town) comes from urvus, the furrow cut by a plough – in this case, by that of Romulus. On the Capitoline hill, at noon on April 21 every year, a special bell called Patarina rings from the Campidoglio to commemorate the founding of Rome. On that occasion, the famous cannon of Gianicolo remains silent, the only day in the year on which it does not sound.

Roman Empire

:For other uses, see Roman Empire (disambiguation) The Roman Empire is the term conventionally used to describe the Ancient Roman polity in the centuries following its reorganization under the leadership of Octavian (better known as Caesar Augustus), until its radical reformation in what was later to be known as the Byzantine Empire. Roman Empire is also used as translation of the expression Imperium Romanum, probably the best known Latin expression where the word "imperium" is used in the meaning of a territory, the "Roman Empire", as that part of the world where Rome ruled. The expansion of this Roman territory beyond the borders of the initial city-state of Rome had started long before the state organisation turned into an Empire. One of the first historians to describe this expansion of the Roman territory was the Greek Polybius, writing in the Epoch of the Roman Republic. In the centuries before the autocracy of Augustus, Rome had already accumulated a collection of tribute-states beyond the Italian Peninsula, including former Mediterranean competitors Syracuse and Carthage. In the late Republic Augustus (then still "Octavian") added Egypt definitively to the Imperium Romanum. The remainder of this article treats the Roman Empire as Imperial state (see Roman Kingdom and Roman Republic for development of the territory in earlier times). Augustus' reforms turning the Roman state into an Empire survived mostly unchanged until the Diocletian reform at end of the 3rd century, which turned the empire into a tetrarchy. While the political form given by Diocletian was short-lived, it led to the division of the Empire into two halves. This allowed Roman rule to continue for two more centuries over the whole empire, although divided into the Eastern and the Western Roman Empire. The end of the Western Empire is traditionally set in 476, when Odovacar deposed the last Emperor and sent the Imperial insignia to Constantinople; henceforth he nominally ruled as dux on behalf of Constantinople. After another millennium, in 1453, the Eastern Empire, better known as the Byzantine Empire, fell to the Ottoman Turks. From Augustus to the Fall of the Western Empire Rome dominated the region of Western Eurasia, comprising over half its population. The Roman Empire's influence on government, law, military, and monumental architecture, as well as many other aspects of Western life remains inescapable. The Greeks adopted the Roman name in the Middle Ages and were known as Romans, a trend that survives until today in Greece, a result of their cultural position (see Names of the Greeks). Roman titles of power were adopted by successor states and other entities with imperial pretensions, including the Frankish kingdom, the Holy Roman Empire, the first and second Bulgarian empires, the Russian/Kiev dynasties, and the German Empire. See also Roman culture.
Historians' viewpoints on the evolution of Imperial Rome
Because the empire of Rome lasted for such a long period of time (31 BC–1453), there are certain alternative names used by historians to distinguish various semantic periods or eras. Such names include Byzantine Empire, Eastern Roman Empire and Western Roman Empire, which are used interchangeably throughout this article to mean the same as Roman Empire (or the Western or Eastern part thereof). For many years historians made a distinction between the Principate, the period from Augustus until the Crisis of the Third Century, and the Dominate, the period from Diocletian until the end of the Empire in the West. According to this theory, during the Principate (from the Latin word princeps, meaning "first citizen", the only title Augustus would permit himself) the realities of dictatorship were concealed behind Republican forms; while during the Dominate (from the word dominus, meaning "Master") imperial power showed its naked face, with golden crowns and ornate imperial ritual. More recently historians established that the situation was far more nuanced: certain historical forms continued until the Byzantine period, more than one thousand years after they were created, and displays of imperial majesty were common from the earliest days of the Empire.
Age of Augustus (31 BC–AD 14)

Political developments
Latin As a matter of convenience, the Roman Empire is held to have begun with the constitutional settlement following the Battle of Actium in 31 BC. In fact the Republican institutions at Rome had been destroyed over the preceding century and Rome had been in continuous crisis with periods of dictatorial rule since Sulla. The long, peaceful and consensual reign of Augustus greatly changed the view toward hereditary monarchy. Rome–the city that had not too long before assassinated its leader, Julius Caesar, when his ambitions seemed to threaten the republic–now placidly accepted one man rule. Augustus' reign was notable for several long-lasting achievements that would define the Empire:
- Creation of an hereditary office, which we refer to as Emperor of Rome.
- Fixation of the payscale. Duration of Roman military service marked the final step in the evolution of the Roman Army from a citizen army to a professional one.
- Creation of the Praetorian Guard, which would make and unmake emperors for centuries.
- Expansion to the natural borders of the Empire. The borders reached upon Augustus' death remained the limits of Empire, with minimal exceptions, for the next four hundred years.
- Development of trade links with regions as far as India and China.
- Creation of a civil service outside of the Senatorial structure, leading to a continuous weakening of Senatorial authority.
- Enactment of the lex Julia of 18 BC and the lex Papia Poppaea of AD 9, which rewarded childbearing and penalized celibacy.
- Promulgation of the cult of the Deified Julius Caesar throughout the Empire. This tradition of deifying the Emperor upon his death lasted until the time of Constantine, who was made both a Roman god and "the Thirteenth Apostle" upon his death.
Cultural developments
:Main article: Roman culture The Augustan period saw a tremendous outpouring of cultural achievement in the areas of poetry, history, sculpture and architecture. At the same time, a tremendous outpouring of energy in founding colonies and municipia, unrivalled in Rome before or after, succeeded in Romanizing extensive territories in the East, in Africa, in Hispania and Gaul, beyond those areas that were traditionally within the Roman sphere of influence.
Sources
The Age of Augustus is paradoxically far more poorly documented than the Late Republican period that preceded it. While Livy wrote his magisterial history during Augustus' reign and his work covered all of Roman history through 9 BC, only epitomes survive of his coverage of the Late Republican and Augustan periods. Our important primary sources for this period include the:
- Res Gestae Divi Augusti, Augustus' highly partisan autobiography,
- Historiae Romanae by Velleius Paterculus, a disorganized work which remains the best annals of the Augustan period, and
- Controversiae and Suasoriae of Seneca the Elder. Though primary accounts of this period are few, works of poetry, legislation and engineering from this period provide important insights into Roman life. Archeology, including maritime archeology, aerial surveys, epigraphic inscriptions on buildings, and Augustan coinage, has also provided valuable evidence about economic, social and military conditions. Secondary sources on the Augustan Age include Tacitus, Dio Cassius, Plutarch and Suetonius. Josephus' Jewish Antiquities is the important source for Judea in this period, which became a province during Augustus' reign.
Julio-Claudian dynasty: Augustus' heirs
Augustus, leaving no sons, was succeeded by his stepson Tiberius, the son of his wife Livia from her first marriage. Augustus was a scion of the gens Julia (the Julian family), one of the most ancient patrician clans of Rome, while Tiberius was a scion of the gens Claudia, only slightly less ancient than the Julians. Their three immediate successors were all descended both from the gens Claudia, through Tiberius' brother Nero Claudius Drusus, and from gens Julia, either through Julia Caesaris, Augustus' daughter from his first marriage (Caligula and Nero), or through Augustus' sister Octavia (Claudius). Historians thus refer to their dynasty as "Julio-Claudian".
Tiberius (14–37)
The early years of Tiberius' reign were peaceful and relatively benign. Tiberius secured the power of Rome and enriched her treasury. However, Tiberius' reign soon became characterized by paranoia and slander. In 19, he was popularly blamed for the death of his nephew, the popular Germanicus. In 23 his own son Drusus died. More and more, Tiberius retreated into himself. He began a series of treason trials and executions. He left power in the hands of the commander of the guard, Aelius Sejanus. Tiberius himself retired to live at his villa on the island of Capri in 26, leaving administration in the hands of Sejanus, who carried on the persecutions with relish. Sejanus also began to consolidate his own power; in 31 he was named co-consul with Tiberius and married Livilla, the emperor's niece. At this point he was hoist by his own petard: the Emperor's paranoia, which he had so ably exploited for his own gain, was turned against him. Sejanus was put to death, along with many of his cronies, the same year. The persecutions continued until Tiberius' death in 37.
Caligula (37–41)
At the time of Tiberius' death most of the people who might have succeeded him had been brutally murdered. The logical successor (and Tiberius' own choice) was his grandnephew, Germanicus' son Gaius (better known as Caligula). Caligula started out well, by putting an end to the persecutions and burning his uncle's records. Unfortunately, he quickly lapsed into illness. The Caligula that emerged in late 37 may have suffered from epilepsy, and was probably insane. He ordered his soldiers to invade Britain, but changed his mind at the last minute and had them pick sea shells on the northern end of France instead. It is believed he carried on incestuous relations with his sisters. He had ordered a statue of himself to be erected in the Temple at Jerusalem, which would have undoubtedly led to revolt had he not been dissuaded. In 41, Caligula was assassinated by the commander of the guard Cassius Chaerea. The only member left of the imperial family to take charge was another nephew of Tiberius', Tiberius Claudius Drusus Nero Germanicus, better known as the emperor Claudius.
Claudius (41–54)
Claudius had long been considered a weakling and a fool by the rest of his family. He was, however, neither paranoid like his uncle Tiberius, nor insane like his nephew Caligula, and was therefore able to administer the empire with reasonable ability. He improved the bureaucracy and streamlined the citizenship and senatorial rolls. He also proceeded with the conquest and colonization of Britain (in 43), and incorporated more Eastern provinces into the empire. In Italy, he constructed a winter port at Ostia, thereby providing a place for grain from other parts of the Empire to be brought in inclement weather. On the home front, Claudius was less successful. His wife Messalina cuckolded him; when he found out, he had her executed and married his niece, Agrippina the younger. She, along with several of his freedmen, held an inordinate amount of power over him, and very probably killed him in 54. Claudius was deified later that year. The death of Claudius paved the way for Agrippina's own son, the 16-year-old Lucius Domitius, or, as he was known by this time, Nero.
Nero (54–69)
Initially, Nero left the rule of Rome to his mother and his tutors, particularly Lucius Annaeus Seneca. However, as he grew older, his desire for power increased; he had his mother and tutors executed. During Nero's reign, there were a series of riots and rebellions throughout the Empire: in Britain, Armenia, Parthia, and Judaea. Nero's inability to manage the rebellions and his basic incompetence became evident quickly and in 68, even the Imperial guard renounced him. Nero is best remembered by the rumour that he played the lyre and sang during the Great Fire of Rome, and hence "fiddled while Rome burned" (though the fiddle had yet to be invented). Nero is also remembered for his immense rebuilding of Rome following the fires. Nero committed suicide, and the year 69 (known as the Year of the Four Emperors) was a year of civil war, with the emperors Galba, Otho, Vitellius, and Vespasian ruling in quick succession. By the end of the year, Vespasian was able to solidify his power as emperor of Rome.
Flavian Dynasty
The Flavians, although a relatively short lived dynasty, helped restore stability in an empire on its knees. Although there are criticism of all three, especially based on their more centralized style of rule, it was through the reforms and good rule of the three that helped create a stable empire that would last well into the 3rd Century. However, their backgrounds as a military dynasty led to further irrelevancy of the senate, and the move from princeps, or first citizen, to imperator, or emperor, was finalized during their reign.
Vespasian (69–79)
Vespasian was a remarkably successful Roman general who had been given rule over much of the eastern part of the Roman Empire. He had supported the imperial claims of Galba; however, on his death, Vespasian became a major contender for the throne. After the suicide of Otho, Vespasian was able to hijack Rome's winter grain supply in Egypt, placing him in a good position to defeat his remaining rival, Vitellius. On December 20, 69, some of Vespasian's partisans were able to occupy Rome. Vitellius was murdered by his own troops, and the next day, Vespasian was confirmed as Emperor by the Senate. At the age of 60 and battle hardened he was hardly a charismatic emperor, but he turned out to be an excellent ruler none the less. Although Vespasian was considered quite the autocrat by the senate, he mostly continued the weakening of that body that had been going since the reign of Tiberius. This was typified by his dating his accession to power from July 1, when his troops proclaimed him emperor, instead of December 21, when the Senate confirmed his appointment. Another example was his assumption of the censorship in 73, giving him power over who exactly made up the senate. He used that power to expel dissident senators. At the same time, he increased the number of senators from 200, at that low level due to the actions of Nero and the year of crisis that followed, to 1000, most of the new senators coming not from Rome but from Italy and the urban centers within the western provinces. Vespasian was able to liberate Rome from the financial burdens placed upon it by Nero's excesses and the civil wars. To do this, he not only increased taxes, but created new forms of taxation. Also, through his power as censor he was able to carefully examine the fiscal status of every city and province, many paying taxes based upon information and structures more than a century old. Through this sound fiscal policy, he was able to build up a surplus in the treasury and embark on public works projects. It was he who first commissioned the Roman Colosseum; he also built a forum whose centerpiece was a temple to Peace. In addition, he alloted sizable subsidies to the arts, creating a chair of rhetoric at Rome. Vespasian was also an effective emperor for the provinces in his decades of office, having posts all across the empire, both east and west. In the west he gave considerable favoritism to Spain in which he granted Latin rights to over three hundred towns and cities, promoting a new era of urbanization throughout the western (i.e. formerly barbarian) provinces. Through the additions he made to the Senate he allowed greater influence of the provinces in the Senate, helping to promote unity in the empire. He also extended the borders of the empire on every front, most of which was done to help strengthen the frontier defenses, one of Vespasian's main goals. The crisis of 69 had wrought havoc on the army. One of the most marked problems had been the support lent by provincial legions to men who supposedly represented the best will of their province. This was mostly caused by the placement of native auxiliary units in the areas they were recruited in, a practice Vespasian stopped. He mixed auxiliary units with men from other areas of the empire or moved the units away from where they were recruited to help stop this. Also, to further reduce the chances of another military coup he broke up the legions, and instead of placing them in singular concentrations broke them up along the border. Perhaps the most important military reform he undertook was the extension of legion recruitment from exclusively Italy to Gaul and Spain, in line with the Romanization of those areas.
Titus (79–81)
Titus, the eldest son of Vespasian, had been groomed to rule. He had served as an effective general under his father, helping to secure the east and eventually taking over the command of Roman armies in Syria and Palestine, quelling the significant Jewish revolt going on at the time. Throughout his father's reign he had been tailored for rule, sharing the consul for several years with his father and receiving the best tutelage. Although there was some trepidation when he took office due to his known dealings with some of the less respectable elements of Roman society, he quickly proved his merit, even recalling many exiled by his father as a show of good faith. However, his short reign was marked by disaster: in 79, Vesuvius erupted in Pompeii, and in 80, a fire decimated much of Rome. His generosity in rebuilding after these tragedies made him very popular. Titus was very proud of his work on the vast amphitheater begun by his father. He held the opening ceremonies in the still unfinished edifice during the year 80, celebrating with a lavish show that featured 100 gladiators and lasted 100 days. Titus died in 81, at the age of 41 of what is presumed to be illness; it was rumored that his brother Domitian murdered him in order to become his successor, although these claims have little merit. Whatever the case, he was greatly mourned and missed.
Domitian (81–96)
The Flavians all had rather poor relations with the senate due to their more autocratic style, however Domitian was the only one who truly created significant problems. His continuous control as consul and censor throughout his rule, the former his father sharing in much the same way of his Julio-Claudian forerunners, the latter having difficulty even obtaining, were unheard of. In addition, he often appeared in full military regalia as an imperator, an affront to the idea of what the Principate-era emperor's power was based upon, the emperor as the princeps. His reputation in the Senate aside, he kept the people of Rome happy through various measures, including donations to every resident of Rome, wild spectacles in the newly finished Colosseum, and continuing the public works projects of his father and brother. He also apparently had the good fiscal sense of his father, because although he spent lavishly his successors came to power with a well endowed treasury. However, during the end of his reign Domitian became extremely paranoid which probably had its initial roots in the treatment he received by his father: although given significant responsibility, he was never trusted with anything important without supervision. This flowered into the severe and perhaps pathological repercussions following the short lived rebellion in 89 of Antonius Saturninus, a governor and commander in Germany. Domitian's paranoia led to a large number of arrests, executions, and seizure of property (which might help explain his ability to spend so lavishly). Eventually it got to the point where even his closest advisers and family members lived in fear, leading them to his murder in 96 orchestrated by his enemies in the Senate, Stephanus (the steward of the deceased Julia Flavia), members of the Pretorian Guard and empress Domitia Longina.
The Adoptive Emperors

"Five Good Emperors" (96–180)
180 The next century came to be known as the period of the "Five Good Emperors", in which the succession was peaceful though not dynastic and the Empire was prosperous. The emperors of the period were Nerva (96–98), Trajan (98–117), Hadrian (117–138), Antoninus Pius (138–161) and Marcus Aurelius (161–180), each being adopted by his predecessor as his successor during the latter's lifetime. While their respective choices of successor were based upon the merits of the individual men they selected, many argue the real reason for the lasting success of the adoptive scheme of succession lay more with the fact that none of them had a natural heir. Under Trajan, the Empire's borders briefly achieved their maximum extension with provinces created in Mesopotamia in 117. From 166, Roman embassies to China, first sent under the reign of Antonius Pius and probably traveling on the southern sea route, are recorded in Chinese historical sources such as the Later Han History.
Commodus (180–192)
192 world map, indicating "Sinae" (China) at the extreme right, beyond the island of "Trapobane" (Sri Lanka, oversized) and the "Aurea Chersonesus" (South-East Asian peninsula).]] The period of the "five good emperors" was brought to an end by the reign of Commodus from 180 to 192. Commodus was the son of Marcus Aurelius, making him the first direct successor in a century, breaking the scheme of adoptive successors that had turned out so well. He was co-emperor with his father from 177. When he became sole emperor upon the death of his father in 180, it was at first seen as a hopeful sign by the people of the Roman Empire. Nevertheless, as generous and magnanimous as his father was, Commodus turned out to be just the opposite. Commodus is often thought to have been insane, and he was certainly given to excess. He began his reign by making an unfavorable peace treaty with the Marcomanni, who had been at war with Marcus Aurelius. Commodus also had a passion for gladiatorial combat, which he took so far as to take to the arena himself, dressed as a gladiator. In 190, a part of the city of Rome burned, and Commodus took the opportunity to "re-found" the city of Rome in his own honor, as Colonia Commodiana. The months of the calendar were all renamed in his honor, and the senate was renamed as the Commodian Fortunate Senate. The army became known as the Commodian Army. Commodus was strangled in his sleep in 192, a day before he planned to march into the Senate dressed as a gladiator to take office as a consul. Upon his death, the Senate passed damnatio memoriae on him and restored the proper name to the city of Rome and its institutions. The popular movies The Fall of the Roman Empire (1964) and Gladiator (2000) were loosely based on the career of the emperor Commodus, although they should not be taken as an accurate historical depictions of his life.
Severan dynasty (193–235)
The Severan dynasty includes the increasingly troubled reigns of Septimius Severus (193–211), Caracalla (211–217), Macrinus (217–218), Elagabalus (218–222), and Alexander Severus (222–235). The founder of the dynasty, Lucius Septimius Severus, belonged to a leading native family of Leptis Magna in Africa who allied himself with a prominent Syrian family by his marriage to Julia Domna. Their provincial background and cosmopolitan alliance, eventually giving rise to imperial rulers of Syrian background, Elagabalus and Alexander Severus, testifies to the broad political franchise and economic development of the Roman empire that had been achieved under the Antonines. A generally successful ruler, Septimius Severus cultivated the army's support with substantial remuneration in return for total loyalty to the emperor and substituted equestrian officers for senators in key administrative positions. In this way, he successfully broadened the power base of the imperial administration throughout the empire. Abolishing the regular standing jury courts of Republican times, Septimius Severus was likewise able to transfer additional power to the executive branch of the government, of which he was decidedly the chief representative. Septimius Severus' son, Marcus Aurelius Antoninus — nicknamed Caracalla — removed all legal and political distinction between Italians and provincials, enacting the Constitutio Antoniniana in 212 which extended full Roman citizenship to all free inhabitants of the empire. Caracalla was also responsible for erecting the famous Baths of Caracalla in Rome, their design serving as an architectural model for many subsequent monumental public buildings. Increasingly unstable and autocratic, Caracalla was assassinated by the praetorian prefect Macrinus in 217, who succeeded him briefly as the first emperor not of senatorial rank. The imperial court, however, was dominated by formidable women who arranged the succession of Elagabalus in 218, and Alexander Severus, the last of the dynasty, in 222. In the last phase of the Severan principate, the power of the Senate was somewhat revived and a number of fiscal reforms were enacted. Despite early successes against the Sassanian Empire in the East, Alexander Severus' increasing inability to control the army led eventually to its mutiny and his assassination in 235. The death of Alexander Severus ushered in a subsequent period of soldier-emperors and almost a half-century of civil war and strife.
Crisis of the 3rd Century (235–284)
The Crisis of the 3rd Century is a commonly applied name for the crumbling and near collapse of the Roman Empire between 235 and 284. During this period, Rome was ruled by more than 35 individuals, most of them prominent generals who assumed Imperial power over all or part of the empire, only to lose it by defeat in battle, murder, or death. After nearly 50 years of external invasion, internal civil wars and economic collapse, the Empire was on the verge of ending. A series of tough soldier-emperors saved the empire, but in the process fundamentally changed the Roman Empire. The transitions of this period mark the beginnings of Late Antiquity and the end of Classical Antiquity.
Tetrarchy (285–324)
324 sacked from a Byzantine palace in 1204, Treasury of St Mark's, Venice]] The transition from a single united empire to the later divided Western and Eastern empires was a gradual transformation. In July, 285, Diocletian defeated rival Emperor Carinus and briefly became sole emperor of the Roman Empire. Diocletian saw that the vast Roman Empire was ungovernable by a single emperor in the face of internal pressures and military threats on two fronts. He therefore split the Empire in half along a north-west axis just east of Italy, and created two equal Emperors to rule under the title of Augustus. Diocletian was Augustus of the eastern half, and gave his long time friend Maximian the title of Augustus in the western half. In 293 authority was further divided as each Augustus took a Caesar to aid him in administrative matters, and to provide a line of succession; Galerius became the junior emperor of Diocletian and Constantius Chlorus the junior emperor of Maximian. This constituted what is called the Tetrarchy (in Greek: the leadership of four) by modern scholars. The system allowed the peaceful succession of the Augusti as the Caesar in each half rose up to replace the Augustus and proclaimed a new Caesar. On May 1, 305 Diocletian and Maximian abdicated in favor of their Caesars. Galerius named the two new Caesars: his nephew Maximinus for himself and Flavius Valerius Severus for Constantius. The Tetrarchy would effectively collapse with the death of Constantius Chlorus on July 25 306. Constantius' troops in Eboracum immediately proclaimed his son Constantine an Augustus. In August, 306, Galerius promoted Severus to the position of Augustus. A revolt in Rome supported another claimant to the same title: Maxentius, son of Maximian, who was proclaimed Augustus on October 28, 306. His election was supported by the Praetorian Guard. This left the Empire with five rulers: four Augusti (Galerius, Constantine, Severus and Maxentius) and a Caesar (Maximinus). The year 307 saw the return of Maximian to the role of Augustus alongside his son Maxentius creating a total of six rulers of the Empire. Galerius and Severus campaigned against them in Italy. Severus was killed under command of Maxentius on September 16, 307. The two Augusti of Italy also managed to ally themselves with Constantine by having Constantine marry Fausta, the daughter of Maximian and sister of Maxentius. The end of 307 saw the Empire with four Augusti (Maximian, Galerius, Constantine and Maxentius) and a sole Caesar (Maximinus). The five were briefly joined by another Augustus in 308, Domitius Alexander, vicarius of the Roman province of Africa under Maxentius, proclaimed himself Augustus. Before long he was captured by Rufius Volusianus and Zenas. Alexander was executed in 311. The current situation of conflict between the various rivalrous Augusti was resolved in the Congress of Carnuntum with the participation of Diocletian, Maximian and Galerius. The final decisions were taken on November 11, 308:
- Galerius remained Augustus of the Eastern Roman Empire.
- Maximinus remained Caesar of the Eastern Roman Empire.
- Maximian was forced to abdicate.
- Maxentius was still not recognized, his rule remained illegitimate.
- Constantine received official recognition but was demoted to Caesar of the Western Roman Empire.
- Licinius replaced Maximian as Augustus of the Western Roman Empire. Problems however continued. Maximinus demanded to be promoted to Augustus. He proclaimed himself to be one on May 1 310; Constantine followed suit shortly after. Maximian similarly proclaimed himself an Augustus for a third and final time. He was killed by his son-in-law Constantine in July, 310. The end of the year again found the Empire with four legitimate Augusti (Galerius, Maximinus, Constantine and Licinius) and one illegitimate one (Maxentius). Galerius died in May 311 leaving Maximinus sole ruler of the Eastern Roman Empire. Meanwhile Maxentius declared a war on Constantine under the pretext of avenging his executed father. He was among the casualties of the Battle of Milvian Bridge on October 28 312. This left the Empire in the hands of the three remaining Augusti, Maximinus, Constantine and Licinius. Licinius allied himself with Constantine, cementing the alliance by marriage to his younger half-sister Constantia in March 313 and joining open conflict with Maximinus. In August 313 Maximinus met his death at Tarsus in Cilicia. The two remaining Augusti divided the Empire again in the pattern established by Diocletian, Constantine becoming Augustus of the Western Roman Empire and Licinius Augustus of the Eastern Roman Empire. This division lasted ten years until 324. A final war between the last two remaining Augusti ended with the deposition of Licinius and the elevation of Constantine to sole Emperor of the Roman Empire. Deciding that the empire needed a new capital, Constantine chose the site of Byzantium for the new city. He refounded it as Nova Roma, but it was popularly called Constantinople: Constantine's City.
Christian Empire (324–395)
395 The beginning of the Roman Empire as a Christian empire lies in 313, with the Edict of Milan. The edict was signed under the reigns of Constantine I and Licinius. The edict established tolerance for Christianity throughout the Empire, but did not yet make it the official state religion. After the Edict was proclaimed, however, the Christian Church rapidly became extremely influential amongst the ruling classes of the Empire, and the Bishops were established in positions of power and influence. Christianity became the single official religion of Rome under Theodosius I (r. 379–395). The emperor had a considerable degree of control over the church. While Christianity flourished, the Empire by no means became uniformly Christian; paganism remained significant. Theodosius massacred Thessalonica for rebelling against his new Christian policies condemning homosexuality, which was a common practice in both ancient Greece and Greece under Roman rule. Upon his return to Rome the Bishop Ambrose refused to let Theodosius enter the church until he made a public repentance. Theodosius did so, and from then on the church's powers grew. Eventually the church would gain enough power that it would outlast the empire in the west.
Late Antiquity in the West (395–476)
476.]] In popular history, the year 476 is generally accepted as the end of the Western Roman Empire. In that year, Odoacer disposed of his puppet Romulus Augustus (475–476), and for the first time did not bother to induct a successor, choosing instead to rule as a representative of the Eastern Emperor (although Julius Nepos, the emperor deposed by Romulus Augustulus, continued to rule Illyricum until his death in 480, at which point Odoacer annexed the remainder of the Western Empire to his Italian kingdom). The last Emperor who ruled from Rome, however, had been Theodosius, who removed the seat of power to Mediolanum (Milan). Edward Gibbon, in writing The History of the Decline and Fall of the Roman Empire knew not to end his narrative at 476. The great corpse continued to twitch, into the 6th century. On the other hand, in 409, with the Emperor of the West fled from Milan to Ravenna and all the provinces wavering in loyalties, the Goth Alaric I, in charge at Rome, came to terms with the senate, and with their consent set up a rival emperor and invested the prefect of the city, a Greek named Priscus Attalus, with the diadem and the purple robe. In the following year when the Goths rampaged in the City, local power was in the hands of the Bishop of Rome. The transfer of power to Christian pope and military dux had been effected: the Western Empire was effectively dead, though no contemporary knew it. The next seven decades played out as aftermath. Theodoric the Great as King of the Goths, couched his legitimacy in diplomatic terms as being the representative of the Emperor of the East. Consuls were appointed regularly through his reign: a formula for the consular appointment is provided in Cassiodorus' Book VI. The post of consul was last filled in the west by Theodoric's successor, Athalaric, until he died in 534. Ironically the Gothic War in Italy, which was meant as the reconquest of a lost province for the Emperor of the East and a re-establishment of the continuity of power, actually caused more damage and cut more ties of continuity with the Antique world than the attempts of Theodoric and his minister Cassiodorus to meld Roman and Gothic culture within a Roman form. In essence, the "fall" of the Roman Empire to a contemporary depended a great deal on where they were and their status in the world. On the great villas of the Italian Campagna, the seasons rolled on without a hitch. The local overseer may have been representing an Ostrogoth, then a Lombard duke, then a Christian bishop, but the rhythm of life and the horizons of the imagined world remained the same. Even in the decayed cities of Italy consuls were still elected. In Auvergne, at Clermont, the Gallo-Roman poet and diplomat Sidonius Apollinaris, bishop of Clermont, realized that the local "fall of Rome" came in 475, with the fall of the city to the Visigoth Euric. In the north of Gaul the Franks could not be taken for Roman, but in Hispania the last Arian Visigothic king Liuvigild considered himself the heir of Rome. In Alexandria, dreams of a "Christian Empire" with genuine continuity were shattered when a rampaging mob of Christians were encouraged to sack and destroy the Serapeum in 392. Hispania Baetica was still essentially Roman when the Moors came in 711, but in the northwest, the invasion of the Suevi broke the last frail links with Roman culture in 409. In Aquitania and Provence, cities like Arles were not abandoned, but Roman culture in Britain collapsed in waves of violence after the last legions evacuated: the final legionary probably left Britain in 409. In Athens the end came for some in 529, when the Emperor Justinian closed the Neoplatonic Academy and its remaining members fled east for protection under the rule of Sassanid king Khosrau I; for other Greeks it had come long before, in 396, when Christian monks led Alaric I to vandalize the site of the Eleusinian Mysteries.
From Roman to Byzantine in the East

Under Constantine (330–337) and his sons (337–361)
Constantinople would serve as the capital of Constantine the Great from May 11, 330 to his death on May 22 337. The Empire was parted again among his three surviving sons.The Western Roman Empire was divided among the eldest son Constantine II and the youngest son Constans. The Eastern Roman Empire along with Constantinople were the share of middle son Constantius II. Constantine II was killed in conflict with his youngest brother in 340. Constans was himself killed in conflict with army proclaimed Augustus Magnentius on January 18 350. Magnentius was at first opposed in the city of Rome by self-proclaimed Augustus Nepotianus, a paternal first cousin of Constans. Nepotianus was killed alongside his mother Eutropia. His other first cousin Constantia convinced Vetriano to proclaim himself Caesar in opposition to Magnentius. Vetriano served a brief term from March 1 to December 25 350. He was then forced to abdicate by the legitimate Augustus Constantius. The usurper Magnentius would continue to rule the Western Roman Empire till 353 while in conflict with Constantius. His eventual defeat and suicide left Constantius as sole Emperor. Constantius' rule would however be opposed again in 360. He had named his paternal half-cousin and brother-in-law Julian as his Caesar of the Western Roman Empire in 355. During the following five years, Julian had a series of victories against invading Germanic tribes, including the Alamanni. This allowed him to secure the Rhine frontier. His victorious Gallic troops thus ceased campaigning. Constantius send orders for the troops to be transferred to the east as reinforcements for his own currently unsuccessful campaign against Shapur II of Persia. This order led the Gallic troops to an insurrection. They proclaimed their commanding officer Julian to be an Augustus. Both Augusti were not ready to lead their troops to another Roman Civil War. Constantius' timely demise on November 3, 361 prevented this war from ever occurring.
Under Julian & Jovian (361–364)
Julian would serve as the sole Emperor for two years. He had received his baptism as a Christian years before, but apparently no longer considered himself one. His reign would see the ending of restriction and persecution of paganism introduced by his uncle and father-in-law Constantine the Great and his cousins and brothers-in-law Constantine II, Constans and Constantius II. He instead placed similar restrictions and unofficial persecution of Christianity. His edict of toleration in 362 ordered the reopening of pagan temples and the reinstitution of alienated temple properties, and, more problematically for the Christian Church, the recalling of previously exiled Christian bishops. Returning Orthodox and Arian bishops resumed their conflicts, thus further weakening the Church as a whole. Julian himself was not a traditional pagan. His personal beliefs were largely influenced by Neoplatonism and Theurgy; he reputedly believed he was the reincarnation of Alexander the Great. He produced works of philosophy arguing his beliefs. His brief renaissance of paganism would, however, end with his death. Julian eventually resumed the war against Shapur II of Persia. He received a mortal wound in battle and died on June 26, 363. He was considered a hero by pagan sources of his time and a villain by Christian ones. Later historians have treated him as a controversial figure. Julian died childless and with no designated successor. The officers of his army elected the rather obscure officer Jovian emperor. He is remembered for signing an unfavorable peace treaty with Persia and restoring the privileges of Christianity. He is considered a Christian himself, though little is known of his beliefs. Jovian himself died on February 17, 364.
Valentinian Dynasty (364–392)
The role of choosing a new Augustus fell again to army officers. On February 28, 364, Pannonian officer Valentinian I was elected Augustus in Nicaea, Bithynia. However, the army had been left leaderless twice in less than a year, and the officers demanded Valentinian to choose a co-ruler. On March 28 Valentinian chose his own younger brother Valens and the two new Augusti parted the Empire in the pattern established by Diocletian: Valentinian would administer the Western Roman Empire, while Valens took control over the Eastern Roman Empire. Valens' election would soon be disputed. Procopius, a Cilician maternal cousin of Julian, had been considered a likely heir to his cousin but was never designated as such. He had been in hiding since the election of Jovian. In 365, while Valentinian was at Paris and then at Reims to direct the operations of his generals against the Alamanni, Procopius managed to bribe two legions assigned to Constantinople and take control of the Eastern Roman capital. He was proclaimed Augustus on September 28 and soon extended his control to both Thrace and Bithynia. War between the two rival Eastern Roman Emperors continued until Procopius was defeated. Valens had him executed on May 27, 366. On August 4 367, a 3rd Augustus was proclaimed by the other two. His father Valentini

Julian calendar

The Julian calendar was introduced in 46 BC by Julius Caesar and took force in 45 BC (709 ab urbe condita). It was chosen after consultation with the Alexandrian astronomer Sosigenes and was probably designed to approximate the tropical year, known at least since Hipparchus. It has a regular year of 365 days divided into 12 months, and a leap day is added to February every four years. Hence the Julian year is on average 365.25 days long. The Julian calendar remained in use into the 20th century in some countries and is still used by many national Orthodox churches. However, too many leap days are added with respect to the astronomical seasons on this scheme. On average, the astronomical solstices and the equinoxes advance by about 11 minutes per year against the Julian year, causing the calendar to gain a day about every 134 years. While Hipparchus and presumably Sosigenes were aware of the discrepancy, although not of its correct value, it was evidently felt to be of little importance. However, it accumulated significantly over time, and eventually led to the reform of 1582, which replaced the Julian calendar with the more accurate Gregorian calendar. The notation "Old Style" (OS) is sometimes used to indicate a date in the Julian calendar, as opposed to "New Style", which indicates a date in the Gregorian Calendar. This notation is used when there might otherwise be confusion about which date is found in a text.

From Roman to Julian

The ordinary year in the previous Roman calendar consisted of 12 months, for a total of 355 days. In addition, an intercalary month, the Mensis Intercalaris, was sometimes inserted between February and March. This intercalary month was formed by inserting 22 days before the last five days of February, creating a 27-day month. It began after a truncated February having 23 or 24 days, so that it had the effect of adding 22 or 23 days to the year, forming an intercalary year of 377 or 378 days. According to the later writers Censorinus and Macrobius, the ideal intercalary cycle consisted of ordinary years of 355 days alternating with intercalary years, which were alternately 377 and 378 days long. On this system, the average Roman year would have had 366¼ days over four years, giving it an average drift of one day per year relative to any solstice or equinox. Macrobius describes a further refinement wherein, for 8 years out of 24, there were only three intercalary years each of 377 days. This refinement averages the length of the year to 365¼ days over 24 years. In practice, intercalations did not occur schematically according to these ideal systems, but were determined by the pontifices. So far as can be determined from the historical evidence, they were much less regular than these ideal schemes suggest. They usually occurred every second or third year, but were sometimes omitted for much longer, and occasionally occurred in two consecutive years. If managed correctly this system allowed the Roman year, on average, to stay roughly aligned to a tropical year. However, if too many intercalations were omitted, as happened after the Second Punic War and during the Civil Wars, the calendar would drift rapidly out of alignment with the tropical year. Moreover, since intercalations were often determined quite late, the average Roman citizen often did not know the date, particularly if he were some distance from the city. For these reasons, the last years of the pre-Julian calendar were later known as years of confusion. The problems became particularly acute during Julius Caesar's pontificate, 63 BC to 46 BC, when there were only five intercalary months, whereas there should have been eight, and none at all during the five Roman years before 46 BC. The Julian reform was intended to correct this problem permanently. Before it took effect, the missed intercalations during Julius Caesar's pontificate were made up by inserting 67 days (22+23+22) between November and December of 46 BC in the form of two months, in addition to 23 days which had already been added to February. Thus 90 days were added to this last year of the Roman Republican calendar, giving it 445 days. Because it was the last of a series of irregular years, this extra-long year was, and is, referred to as the last year of confusion. The first year of operation of the new calendar was 45 BC.

Leap years error

Despite the new calendar being much simpler than the Roman calendar, the pontifices apparently misunderstood the algorithm. They added a leap day every three years, instead of every four years. According to Macrobius, the error was the result of counting inclusively, so that the four year cycle was considered as including both the first and fourth years. This resulted in too many leap days. Caesar Augustus remedied this discrepancy by restoring the correct frequency after 36 years of this mistake. He also skipped several leap days in order to realign the year. The historic sequence of leap years (i.e. years with a leap day) in this period is not given explicitly by any ancient source, although the existence of the triennial leap year cycle is confirmed by an inscription that dates from 9 or 8 BC. The chronologist Joseph Scaliger established in 1583 that the Augustan reform was instituted in 8 BC, and inferred that the sequence of leap years was 42, 39, 36, 33, 30, 27, 24, 21, 18, 15, 12, 9 BC, AD 8, 12 etc. This proposal is still the most widely accepted solution. It has also sometimes been suggested that 45 BC was a leap year. Other solutions have been proposed from time to time. Kepler proposed in 1614 that the correct sequence of leap years was 43, 40, 37, 34, 31, 28, 25, 22, 19, 16, 13, 10 BC, AD 8, 12 etc. In 1883 the German chronologist Matzat proposed 44, 41, 38, 35, 32, 29, 26, 23, 20, 17, 14, 11 BC, AD 4, 8, 12 etc., based on a passage in Dio Cassius that mentions a leap day in 41 BC that was said to be contrary to (Caesar's) rule. In the 1960s Radke argued the reform was actually instituted when Augustus became pontifex maximus in 12 BC, suggesting the sequence 45, 42, 39, 36, 33, 30, 27, 24, 21, 18, 15, 12 BC, AD 4, 8, 12 etc. In 1999, an Egyptian papyrus was published which gives an ephemeris table for 24 BC with both Roman and Egyptian dates. From this it can be shown that the most likely sequence was in fact 44, 41, 38, 35, 32, 29, 26, 23, 20, 17, 14, 11, 8 BC, AD 4, 8, 12 etc, very close to that proposed by Matzat. This sequence shows that the standard Julian leap year sequence began in AD 4, the twelfth year of the Augustan reform. Also, under this sequence the actual Roman year coincided with the proleptic Julian year between 32 and 26 BC. This suggests that one aim of the realignment portion of the Augustan reform was to ensure that key dates of his career, notably the fall of Alexandria on 1 August 30 BC, were unaffected by his correction. Roman dates before 32 BC were typically a day or two before the day with the same Julian date, so 1 January in the Roman calendar of the first year of the Julian reform actually fell on 31 December 46 BC (Julian date). A curious effect of this is that Caesar's assassination on the Ides (15th day) of March in 44 BC fell on 14 March 44 BC in the Julian calendar.

Naming of the months

Immediately after the Julian reform, the twelve months of the Roman calendar were named Ianuarius, Februarius, Martius, Aprilis, Maius, Iunius, Quintilis, Sextilis, September, October, November, and December, just as they were before the reform. Their lengths were set to their modern values. The old intercalary month, the Mensis Intercalaris, was abolished and replaced with an single intercalary day at the same point (i.e. five days before the end of Februarius). The first month of the year continued to be Ianuarius, as it had been since 153 BC. The Romans later renamed months after Caesar and Augustus, renaming Quintilis (originally, "the Fifth month", with March = month 1) as Iulius (July) in 44 BC and Sextilis ("Sixth month") as Augustus (August) in 8 BC. (Note that the letter J was not invented until the 17th century). Quintilis was renamed to honour Caesar because it was the month of his birth. According to a senatusconsultum quoted by Macrobius, Sextilis was renamed to honour Augustus because several of the most significant events in his rise to power, culminating in the fall of Alexandria, fell in that month. Other months were renamed by other emperors, but apparently none of the later changes survived their deaths. Caligula renamed September ("Seventh month") as Germanicus; Nero renamed Aprilis (April) as Neroneus, Maius (May) as Claudius and Iunius (June) as Germanicus; and Domitian renamed September as Germanicus and October ("Eighth month") as Domitianus. At other times, September was also renamed as Antoninus and Tacitus, and November ("Ninth month") was renamed Faustina and Romanus. Commodus was unique in renaming all twelve months after his own adopted names (January to December): Amazonius, Invictus, Felix, Pius, Lucius, Aelius, Aurelius, Commodus, Augustus, Herculeus, Romanus, and Exsuperatorius. Much more lasting than the ephemeral month names of the post-Augustan Roman emperors were the names introduced by Charlemagne. He renamed all of the months agriculturally into Old High German. They were used until the 15th century, and with some modifications until the late 18th century in Germany and in the Netherlands (January-December): Wintarmanoth (winter month), Hornung (spring), Lentzinmanoth (Lent month), Ostarmanoth (Easter month), Winnemanoth (grazing month), Brachmanoth (plowing month), Heuvimanoth (hay month), Aranmanoth (harvest month), Witumanoth (wood month), Windumemanoth (vintage month), Herbistmanoth (autumn/harvest month), and Heilagmanoth (holy month). Translations of these month names are still used to this day in some Slavic languages, such as Polish.

Lengths of the months

According to the 13th century scholar Sacrobosco, the original scheme for the months in the Julian Calendar was very regular, alternately long and short. From January through December, the month lengths according to Sacrobosco for the Roman Republican calendar were: :30, 29, 30, 29, 30, 29, 30, 29, 30, 29, 30, and 29, totaling 354 days. He then thought that Julius Caesar added one day to every month except February, a total of 11 more days, giving the year 365 days. A leap day could now be added to the extra short February: :31, 29 (30), 31, 30, 31, 30, 31, 30, 31, 30, 31, and 30 He then said Augustus changed this to: :31, 28 (29), 31, 30, 31, 30, 31, 31, 30, 31, 30, and 31 giving us the irregular month lengths which we still use today, so that the length of Augustus would not be shorter than (and therefore inferior to) the length of Iulius. Although this theory is still widely repeated, it is certainly wrong. First, a wall painting of a Roman Republican calendar has survived [http://www.personal.psu.edu/users/w/x/wxk116/RomanCalendar/Fasti4.gif] which confirms the literary accounts that the months were already irregular before Julius Caesar reformed it: :29, 28, 31, 29, 31, 29, 31, 29, 29, 31, 29, and 29 Also, the Julian reform did not change the dates of the Nones and Ides. In particular, the Ides are late (on the 15th rather than 13th) in March, May, July and October, showing that these months always had 31 days in the Roman calendar, whereas Sacrobosco's theory requires that the length of October was changed. Further, Sacrobosco's theory is explicitly contradicted by the third and fifth century authors Censorinus and Macrobius, and, finally, it is inconsistent with seasonal lengths given by Varro, writing in 37 BC, before the Augustan reform, with the 31-day Sextilis given by the new Egyptian papyrus from 24 BC, and with the 28-day February shown in the Fasti Caeretani, which is dated before 12 BC.

Year numbering

The dominant method that the Romans used to identify a year for dating purposes was to name it after the two consuls who took office in it. Since 153 BC, they had taken office on 1 January, and Julius Caesar did not change the beginning of the year. Thus this consular year was an eponymous or named year. Roman years were named this way until the last consul was appointed in 541. Only rarely did the Romans number the year from the founding of the city (of Rome), ab urbe condita (AUC). This method was used by Roman historians to determine the number of years from one event to another, not to date a year. Different historians had several different dates for the founding. The Fasti Capitolini, an inscription containing an official list of the consuls which was published by Augustus, used an epoch of 752 BC. The epoch used by Varro, 753 BC, has been adopted by modern historians. Indeed, Renaissance editors often added it to the manuscripts that they published, giving the false impression that the Romans numbered their years. Most modern historians tacitly assume that it began on the day the consuls took office, and ancient documents such as the Fasti Capitolini which use other AUC systems do so in the same way. However, the Varronian AUC year did not formally begin on 1 January, but on Founder's Day, 21 April. This prevented the early Roman church from celebrating Easter after 21 April because the festivities associated with Founder's Day conflicted with the solemnity of Lent, which was observed until the Saturday before Easter Sunday. In addition to consular years, the Romans sometimes used the regnal year of the emperor. Anno Diocletiani, named after Diocletian, was often used by the Alexandrian Christians to number their Easters during the fourth and fifth centuries. In AD 537, Justinian required that henceforth the date must include the name of the emperor, in addition to the indiction and the consul (the latter ending only four years later). The indiction caused the Byzantine year to begin on 1 September, which is still used in the Eastern Orthodox Church for the beginning of the liturgical year. In AD 525 Dionysius Exiguus proposed the system of anno Domini, which gradually spread through the western Christian world, once the system was adopted by Bede. Years were numbered from the supposed date of the incarnation or annunciation of Jesus on 25 March, although this soon changed to Christmas, then back to Annunciation Day in Britain, and the numbered year even began on Easter in France.

From Julian to Gregorian

The Julian calendar was in general use in Europe from the times of the Roman Empire until 1582, when Pope Gregory XIII promulgated the Gregorian Calendar, which was soon adopted by most Catholic countries. The Protestant countries followed later, and the countries of Eastern Europe even later. Great Britain had Thursday 14 September 1752 follow Wednesday 2 September 1752. Sweden adopted the new style calendar in 1753, but also for a twelve-year period starting in 1700 used a modified Julian Calendar. Russia remained on the Julian calendar until after the Russian Revolution (which is thus called the 'October Revolution' but occurred in November according to the Gregorian calendar), in 1917, while Greece continued to use it until 1923. Although all Eastern European countries had adopted the Gregorian calendar on or before 1923, their national Eastern Orthodox churches had not. A revised Julian calendar was proposed during a synod in Constantinople in May of 1923, consisting of a solar part which was and will be identical to the Gregorian calendar until the year 2800, and a lunar part which calculated Easter astronomically at Jerusalem. All Orthodox churches refused to accept the lunar part, so almost all Orthodox churches continue to celebrate Easter according to the Julian calendar (the Finnish Orthodox Church uses the Gregorian Easter). The solar part was only accepted by some Orthodox churches, those of Constantinople, Alexandria, Antioch, Greece, Cyprus, Romania, Poland, Bulgaria (in 1963), and the Orthodox Church in America (although some OCA parishes are permitted to use the Julian calendar). Thus, these churches celebrate the Nativity on the same day that Western Christians do, 25 December Gregorian until 2800. The Orthodox churches of Jerusalem, Russia, Serbia, Georgia, Ukraine, and the Greek Old Calendarists continue to use the Julian calendar for their fixed dates, thus they celebrate the Nativity on 25 December Julian (7 January Gregorian until 2100).
