Mensis Aprilis

''Aprilis'' or ''mensis Aprilis'' (April) was the second month of the ancient Roman calendar, following ''Martius'' ( March) and preceding ''Maius'' (May). On the oldest Roman calendar that had begun with March, ''Aprilis'' was 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.

April was marked by a series of festivals devoted to aspects of rural life, since it was a busy month for farmers. As Rome became more urbanized, the significance of some ceremonies expanded, notably the Parilia, an archaic pastoral festival celebrated as the "birthday" ''( dies natalis)'' or founding day of Rome. The month was generally preoccupied with deities who were female or ambiguous in gender, opening with the Feast of Venus on the Kalends.

Name of the month

The Romans thought that the name ''Aprilis'' derived from ''aperio, aperire, apertus'', a verb meaning "to open". The ''Fasti Praenestini'' offered the expanded explanation that "fruits and flowers and animals and seas and lands do open".

Some antiquarians, as well as Ovid in his poem on the Roman calendar, provide an alternate derivation from ''Aphrodite'', the Greek counterpart of Venus whose festival began the month. ''Apru'' might be derived from the conjectured Etruscan form of the name, which would be ''Aprodita'', but among the Etruscans, the month was called ''Cabreas''. Some modern linguists derive ''Aprilis'' from Etruscan ''Ampile'' or ''Amphile'', based on a medieval gloss, conjecturing an origin in the Thessalian month name ''Aphrios''. An Indo-European origin has also been proposed, related to Sanskrit ''áparah'' and Latin ''alter'', "the other of two", referring to its original position as the second month of the year. Varro and Cincius both reject the connection of the name to ''Aphrodite'', and the common Roman derivation from ''aperio'' may be the correct one.

In the latter years of Nero's reign, the Senate briefly renamed April ''Neronius'' in his honor.

In the agricultural year

The farmers' almanacs ''( menologia rustica)'' concur that Venus—in Roman religion a goddess of gardens—was the tutelary deity of April, and that sheep were to be purified ''(oves lustrantur)''. In his agricultural treatise, Varro enumerates duties such as weeding crops, breaking ground, cutting willows, fencing meadows, and planting and pruning olives.

The second half of April brought a series of festivals pertaining to farm life:
* April 15: Fordicidia, a festival of agricultural fertility and animal husbandry;
* 21: Parilia, a feast of shepherds;
* 23: Vinalia, one of two wine festivals (the other was held August 19) in the religious year;
* 25: Robigalia to protect crops from blight.

Of these, the Fordicidia and Robigalia are likely to have been of greatest antiquity. William Warde Fowler, whose early 20th-century work on Roman festivals remains a standard reference, asserted that the Fordicidia was "beyond doubt one of the oldest sacrificial rites in Roman religion." The latter part of April was consumed by games ''( ludi)'' in honor of Ceres, the grain goddess thought to have power over growth and the life cycle. The end of the month brought the beginning of the games of Flora, goddess of blooming plants and listed by Varro as one of the twelve principal agricultural deities.

Dates

The Romans did not number days of a month sequentially from the 1st through the last day. Instead, they counted back from the three fixed points of the month: the Nones (5th or 7th), the Ides (13th or 15th), and the Kalends (1st) of the following month. The Nones of April was the 5th, and the Ides the 13th. The last day of April was the ''pridie Kalendas Maias,'' "day before the Kalends of May". Roman counting was inclusive; April 9 was ''ante diem V Idūs Aprilis'', "the 5th day before the Ides of April," usually abbreviated ''a.d. V Id. Apr.'' (or with the ''a.d.'' omitted altogether); April 23 was ''IX Kal. Mai.'', "the 9th day before the Kalends of May," on the Julian calendar ''(VIII Kal. Mai.'' on the pre-Julian calendar).

On the calendar of the Roman Republic and early Principate, each day was marked with a letter to denote its religiously lawful status. In April, these were:
* 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).

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. On the calendar of military religious observances known as the ''Feriale Duranum'', sacrifices pertaining to Imperial cult outnumber the older festivals. After the mid-1st century AD, a number of dates are added to calendars for spectacles and games ''( ludi)'' held in honor of various deities in the venue called a " circus" ''(ludi circenses)''. Festivals marked in large letters on extant ''fasti'', represented by festival names in all capital letters on the table, are thought to have been the most ancient holidays, becoming part of the calendar before 509 BC.Scullard, ''Festivals and Ceremonies of the Roman Republic'', p. 41.

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 for the Julian calendar are given; the pre-Julian date for festivals, when April had one less day, are noted parenthetically.
