The Ides of March is the day on the Roman calendar marked as the Idus, roughly the midpoint of a month, of Martius, corresponding to 15 March on the Gregorian calendar. It was marked by several major religious observances. In 44 BC, it became notorious as the date of the assassination of Julius Caesar, which made the Ides of March a turning point in Roman history.
Jupiter, also known as Jove, is the god of the sky and thunder, and king of the gods in ancient Roman religion and mythology. Jupiter was the chief deity of Roman state religion throughout the Republican and Imperial eras, until Christianity became the dominant religion of the Empire. In Roman mythology, he negotiates with Numa Pompilius, the second king of Rome, to establish principles of Roman religion such as offering, or sacrifice.
A religious festival is a time of special importance marked by adherents to that religion. Religious festivals are commonly celebrated on recurring cycles in a calendar year or lunar calendar. The science of religious rites and festivals is known as heortology.
In the ancient Roman calendar, Quintilis or Quinctilis was the month following Junius (June) and preceding Sextilis (August). Quintilis is Latin for "fifth": it was the fifth month in the earliest calendar attributed to Romulus, which began with Martius and had 10 months. After the calendar reform that produced a 12-month year, Quintilis became the seventh month, but retained its name. In 45 BC, Julius Caesar instituted a new calendar that corrected astronomical discrepancies in the old. After his death in 44 BC, the month of Quintilis, his birth month, was renamed Julius in his honor, hence July.
Sextilis or mensis Sextilis was the Latin name for what was originally the sixth month in the Roman calendar, when March was the first of ten months in the year. After the calendar reform that produced a twelve-month year, Sextilis became the eighth month, but retained its name. It was renamed Augustus (August) in 8 BC in honor of the first Roman emperor, Augustus. Sextilis followed Quinctilis, which was renamed Julius (July) after Julius Caesar, and preceded September, which was originally the seventh month.
The Floralia was a festival of ancient Roman religion in honor of the goddess Flora, held on 27 April during the Republican era, or 28 April in the Julian calendar. The festival included Ludi Florae, the "Games of Flora", which lasted for six days under the empire.
In ancient Roman religion and mythology, Tellus Mater or Terra Mater is the personification of the Earth. Although Tellus and Terra are hardly distinguishable during the Imperial era, Tellus was the name of the original earth goddess in the religious practices of the Republic or earlier. The scholar Varro (1st century BC) lists Tellus as one of the di selecti, the twenty principal gods of Rome, and one of the twelve agricultural deities. She is regularly associated with Ceres in rituals pertaining to the earth and agricultural fertility.
Februarius, fully Mensis Februarius, was the shortest month of the Roman calendar from which the Julian and Gregorian month of February derived. It was eventually placed second in order, preceded by Ianuarius and followed by Martius. In the oldest Roman calendar, which the Romans believed to have been instituted by their legendary founder Romulus, March was the first month, and the calendar year had only ten months in all. Ianuarius and Februarius were supposed to have been added by Numa Pompilius, the second king of Rome, originally at the end of the year. It is unclear when the Romans reset the course of the year so that January and February came first.
The Equirria were two ancient Roman festivals of chariot racing, or perhaps horseback racing, held in honor of the god Mars, one 27 February and the other 14 March.
Ianuarius, Januarius, or January, fully Mensis Ianuarius and abbreviated Ian., was the first month of the ancient Roman calendar, from which the Julian and Gregorian month of January derived. It was followed by Februarius ("February"). In the calendars of the Roman Republic, Ianuarius had 29 days. Two days were added when the calendar was reformed under Julius Caesar in 45 BCE.
Maius or mensis Maius (May) was the fifth month of the ancient Roman calendar in the classical period, following Aprilis (April) and preceding Iunius (June). On the oldest Roman calendar that had begun with March, it was the third of ten months in the year. May had 31 days.
The Aventine Triad is a modern term for the joint cult of the Roman deities Ceres, Liber and Libera. The cult was established c. 493 BC within a sacred district (templum) on or near the Aventine Hill, traditionally associated with the Roman plebs. Later accounts describe the temple building and rites as "Greek" in style. Some modern historians describe the Aventine Triad as a plebeian parallel and self-conscious antithesis to the Archaic Triad of Jupiter, Mars and Quirinus and the later Capitoline Triad of Jupiter, Minerva and Juno. The Aventine Triad, temple and associated ludi served as a focus of plebeian identity, sometimes in opposition to Rome's original ruling elite, the patricians.
Martius or mensis Martius ("March") was the first month of the ancient Roman year until possibly as late as 153 BC. After that time, it was the third month, following Februarius (February) and preceding Aprilis (April). Martius was one of the few Roman months named for a deity, Mars, who was regarded as an ancestor of the Roman people through his sons Romulus and Remus.
Aprilis or mensis Aprilis (April) was the fourth month of the ancient Roman calendar in the classical period, following Martius (March) and preceding Maius (May). On the oldest Roman calendar that had begun with March, Aprilis had been the second of ten months in the year. April had 29 days on calendars of the Roman Republic, with a day added to the month during the reform in the mid-40s BC that produced the Julian calendar.
Mensis Iunius or Iunius, also Junius (June), was the sixth month of the Roman calendar of the classical period, following Maius (May). In the oldest calendar attributed by the Romans to Romulus, Iunius had been the fourth month in a ten-month year that began with March (Martius, "Mars' month"). The month following June was thus called Quinctilis or Quintilis, the "fifth" month. Iunius had 29 days until a day was added during the Julian reform of the calendar in the mid-40s BC. The month that followed Iunius was renamed Iulius (July) in honour of Julius Caesar.
September or mensis September was originally the seventh of ten months on the ancient Roman calendar that began with March. 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.
October or mensis October was the eighth of ten months on the oldest Roman calendar. It had 31 days. October followed September and preceded November. After the calendar reform that resulted in a 12-month year, October became the tenth month, but retained its numerical name, as did the other months from September to December.
November or mensis November was originally the ninth of ten months on the Roman calendar, following October and preceding December. It had 29 days. In the reform that resulted in a 12-month year, November became the eleventh month, but retained its name, as did the other months from September through December. A day was added to November during the Julian calendar reform in the mid-40s BC.
In the Roman Empire of the 4th century, the Ludi Triumphales were games (ludi) held annually September 18–22 to commemorate the victory of Constantine over Licinius at Chalcedon in 324. No description of these games has survived, but they are significant in the historical transformation of Roman religious and state institutions under the Christian emperors, an era inaugurated by the conversion of Constantine. Forty-eight circus races (ludi circenses) are recorded for September 18, which was also celebrated as the birthday (dies natalis) of the emperor Trajan.
December or mensis December was originally the tenth month of the Roman calendar, following November and preceding Ianuarius. It had 29 days. When the calendar was reformed to create a 12-month year starting in Ianuarius, December became the twelfth month, but retained its name, as did the other numbered months from Quintilis (July) to December. Its length was increased to 31 days under the Julian calendar reform.
