September (Roman month)
September (from Latin septem, "seven") or mensis September was originally the seventh of ten months on the ancient Roman calendar that began with March (mensis Martius, "Mars' month"). It had 29 days. After the reforms that resulted in a 12-month year, September became the ninth month, but retained its name. September followed what was originally Sextilis, the "sixth" month, renamed Augustus in honor of the first Roman emperor, and preceded October, the "eighth" month that like September retained its numerical name contrary to its position on the calendar. A day was added to September in the mid-40s BC as part of the Julian calendar reform.
September has none of the archaic festivals that are marked in large letters for other months on extant Roman fasti. Instead, about half the month is devoted to the Ludi Romani, "Roman Games", which developed as votive games for Jupiter Optimus Maximus ("Jupiter Best and Greatest"). The Ludi Romani are the oldest games instituted by the Romans, dating from 509 BC. On the Ides of September (the 13th), Jupiter was honored with a public banquet, the Epulum Jovis. A nail-driving ritual in the temple marked the passing of the political year during the Republican era, and in the earliest period, the consuls took office on the Ides of September. The month was often represented in art by the grape harvest.
September was the birth month of no fewer than four major Roman emperors, including Augustus. The emperor Commodus renamed the month after either himself or Hercules—an innovation that was repealed after his murder in 192. In the Eastern provinces of the Roman Empire, the year began with September on some calendars, and was the beginning of the imperial tax year.
In the agricultural yearEdit
For the month of September, ancient farmers' almanacs (menologia rustica) take note of the autumnal equinox on September 24, and the equal number of daylight and nocturnal hours. They note that the month began with the sun in the astrological sign of Virgo, and was under the guardianship (tutela) of Volcanus (the god Vulcan). On an unspecified date an Epulum Minervae (Banquet of Minerva) is to be held, probably as part of the general epulum on the Ides.
The farmer is instructed to coat wine vessels with pitch, pick apples, and loosen the compacted soil around trees. In his agricultural treatise, Varro assigns farmers additional tasks in the period from the rising of Sirius to the equinox. Straw must be cut, haystacks pitched, arable land ploughed, fodder gathered, and well-watered meadows mown a second time. Columella specifies that sloping ground should be ploughed between the Kalends (1st) and the Ides (13th).
Equinox and medical theoryEdit
The Aëtius parapegma is an almanac that appears as a chapter in the 6th-century Tetrabiblos of Aëtius of Amida. It treats the rising and setting of constellations, weather forecasting, and medical advice as closely intertwined, and notes of the equinox (placed on September 25) that
There is the greatest disturbance in the air for three days previous. Thus it is necessary to be careful neither to phlebotomize, nor purge, nor otherwise to change the body violently from the 15th of September through the 24th.
The passage is presented as advice for physicians, based on the principle that "the bodies of healthy people, and especially those of sick people, change with the condition of the air".
Iconography of the monthEdit
The vintage, with bunches or baskets of grapes, predominates in both verbal and visual allegories of September, particularly in mosaics depicting the months. In the manuscripts that preserve the Calendar of Filocalus (354 AD), September is represented by a nude male wearing only a long light scarf over one shoulder. The conventional bunch of grapes appears under his left hand, outstretched to hold a basket, on the top of which are arrayed five puzzling picks or skewers. Over his right shoulder is placed a basket holding two pyramids of six figs or small flasks. A vessel, presumably to receive the new wine, is sunk into the ground on either side of him. Over the one to his right, he dangles a lizard on a string, a motif that recurs in imagery associated with Dionysus, the god of wine. The exact significance of the lizard is uncertain. It may represent a magico-medical charm to ensure healthy wine, with the lizard either a potent lustration or the potential damage to be warded off. The lizard is also an attribute of Apollo Sauroctonos.
In calendar mosaics from Hellín in Roman Spain and Trier in Gallia Belgica, September is represented by the god Vulcan, the tutelary deity of the month in the menologia rustica, depicted as an old man holding tongs. The mosaic from Hellín (2nd–3rd century) depicts each of the months as a personification with or representing a zodiac sign. September is shown holding balance scales and assisted by Vulcan. The scales represent Libra, the astrological sign entered late in the month. In the Laus omnium mensium ("Praise of All the Months"), a poem dating to the early 6th century, September "divides the hours equally for Libra".
In an ancient Christian mosaic from Gerasa in the province of Arabia (present-day Jordan), September has the typical attributes of a vintager in Roman art—a young man wearing a tunic and chlamys carries a bunch of grapes in his right hand and has a basket on his shoulder—but is labeled as Gorpiaios, the first month of the year in the local calendar, equivalent to the period August 19 to September 17.
The Romans did not number days of a month sequentially from the first day through the last. Instead, they counted back from the three fixed points of the month: the Nones (5th or 7th, depending on the month), the Ides (13th or 15th), and the Kalends (1st) of the following month. The Nones of September was the 5th, and the Ides the 13th. The last day of September was the pridie Kalendas Octobrīs, "day before the Kalends of October". Roman counting was inclusive; September 9 was ante diem V Idūs Septembrīs, "the 5th day before the Ides of September," usually abbreviated a.d. V Id. Sept. (or with the a.d. omitted altogether); September 23 was IX Kal. Oct., "the 9th day before the Kalends of October," on the Julian calendar (VIII Kal. Oct. on the pre-Julian calendar, when September had only 29 days).
- F for dies fasti, days when it was legal to initiate action in the courts of civil law;
- C for dies comitalis, a day on which the Roman people could hold assemblies (comitia), elections, and certain kinds of judicial proceedings;
- N for dies nefasti, when these political activities and the administration of justice were prohibited;
- NP, the meaning of which remains elusive, but which marked feriae, public holidays.
By the late 2nd century AD, extant calendars no longer show days marked with these letters, probably in part as a result of calendar reforms undertaken by Marcus Aurelius. Days were also marked with nundinal letters in cycles of A B C D E F G H, to mark the "market week" (these are omitted in the table below).
On a dies religiosus, one of which occurred on September 14, individuals were not to undertake any new activity, nor do anything other than tend to the most basic necessities. A dies natalis was an anniversary such as a temple founding or rededication, sometimes thought of as the "birthday" of a deity. During the Imperial period, some of the traditional festivals localized at Rome became less important, and the birthdays and anniversaries of the emperor and his family gained prominence as Roman holidays. A dies imperii marked the date of an emperor's accession. Only sacrifices and observances pertaining to Imperial cult are preserved for September on the calendar of military religious observances known as the Feriale Duranum, in part because of its fragmentary condition. After the mid-1st century AD, a number of dates are added to calendars for spectacles and games (ludi) in the venue called a "circus". These ludi circenses were held in honor of various deities, but during September mainly for imperial holidays.
Unless otherwise noted, the dating and observances on the following table are from H.H. Scullard, Festivals and Ceremonies of the Roman Republic (Cornell University Press, 1981), pp. 96–115. After the Ides, dates are given for the 30-day month of the Julian calendar; pre-Julian dates of festivals are noted parenthetically.

Under the emperorsEdit
September has a concentration of imperial birthdays (dies natales): Aurelian on the 9th, Trajan on the 18th, Antoninus Pius on the 19th, and Augustus on the 23rd. Inscriptions throughout the Empire record religious dedications made on these days, often by military personnel. The Genius of Legio II Italica Pia, an Italian legion stationed in Noricum, received a dedication on September 18, 119 AD, the anniversary of Trajan's birth and Nerva's accession. This date may also have been the "birthday" of the unit (natalis aquilae). At least two inscriptions record religious dedications on September 19, the birthday of Antoninus Pius. In the province of Germania Inferior, on this date in 190 AD, a camp prefect (praefectus castrorum) and his three sons dedicated an altar to Jupiter Optimus Maximus (IOM), Hercules, Silvanus, and the Genius of the "divine house" (domus divina, the imperial household). In the same province, a prefect of Legio I Minerviae marked the renovation of a temple to Mars Militaris on September 19, 295, with a dedication to the wellbeing (salus) of the emperor. Several inscriptions record dedications on the birthday of Augustus, including one in honor of the Eagle made in Roman Britain dually to the numen of Augustus and the Genius of Legio II Augusta (144 AD), and an inscribed bronze Genius from Germania Superior donated to an association of standard bearers (246 AD).
There were occasional attempts to rename September, emulating the successful renaming of the Roman months originally called Quinctilis (July, after Julius Caesar) and Sextilis (August, after Augustus). According to Suetonius, Tiberius declined the honor of having September named after himself, and October after his mother Livia. Caligula insisted futilely that September be called Germanicus after his father. Domitian (reigned 81–96 AD) also briefly renamed September, the month of his accession as emperor, mensis Germanicus after the triumph he celebrated over the Germanic Chatti.
More sweepingly, in 184 AD Commodus renamed all the months of the year after names and aspects of himself. Cassius Dio lists Amazonius (January), Invictus, Felix, Pius, Lucius, Aelius, Aurelius, Commodus, Augustus, Herculeus, Romanus, and Exsuperatorius. In this sequence, August as his birth month was renamed Commodus, and September was called by his title Augustus, with each of the months from May to September (Lucius to Augustus) represented by elements of his official nomenclature in their usual order. The Historia Augusta also indicates that August was the month named Commodus, but is internally inconsistent: at one point, Hercules, the patron deity chosen by Commodus, is said to have been the namesake for September, while elsewhere October is the mensis Herculeus, as it is on Dio's list. Several sources from late antiquity—among them Aurelius Victor, Eutropius, and Jerome—state that September was the mensis Commodus. Dates recorded in the month of Commodus are exceedingly rare, with a graffito from Ostia Antica reading VII Kal. Commodas (July 26 or August 26, depending on whether Commodus was August or September); a date of III Nonas Commodias (August 3) in the Historia Augusta; and a fragmentary reference to the Idus Commodas ("Ides of Commodus") on a marble base at Lanuvium. The innovation was repealed after his murder in 192.
The new year in SeptemberEdit
The Byzantine antiquarian Johannes Lydus, in his work on the months (De mensibus), says that the Romans had three new years: priestly, in January; national, in March; and a cyclical or political new year in September. In Republican Rome, the senior magistrate on the Ides of September drove a nail called the clavus annalis ("year-nail") into the wall of the Temple of Jupiter Optimus Maximus. The ceremony occurred on the dies natalis of the temple, when the banquet for Jove was also held. The nail-driving ceremony, however, took place in a sacred space (templum) devoted to Minerva, on the right side of the shrine (aedes) of Jupiter. This ritual predated the common use of written letters, according to the Augustan historian Livy, and was within Minerva's sphere of influence because the concept of "number" was invented by her.
In the Roman East, the birthday of Augustus on September 23 was the first day of the new year on some calendars, including possibly the calendar of Heliopolis (Baalbek in present-day Lebanon). The tax year began in September, when the Praetorian Prefects published their budgets. The unfamiliarity of the Roman year in the Eastern provinces, and the difficulties of coordinating disparate calendars, made it convenient in some instances to date by means of the tax year. In Roman Syria, for instance, the Seleucid year began October 1, but was adjusted to September 1 in the 5th century to coincide with the tax year.
