This is Ovid's poetical calendar of the Roman year, with its various observances and festivals, written in elegiacs. Ovid's design was to study the calendar in the light of old annals, and to show what events are commemorated on each day and the origins of the various events.

Written after he had been banished to the Black Sea city of Tomis by Emperor Augustus, the Fasti is Ovid's last major poetic work. Both a calendar of daily rituals and a witty sequence of stories recounted in a variety of styles, it weaves together tales of gods and citizens together to explore Rome's history, religious beliefs and traditions. It may also be read as a subtle but powerful political manifesto which derides Augustus' attempts to control his subjects by imposing his own mythology upon them: after celebrating the emperor as a Jupiter-on-earth, for example, Ovid deliberately juxtaposes a story showing the king of the gods as a savage rapist. Endlessly playful, this is also a work of integrity and courage, and a superb climax to the life of one of Rome's greatest writers.
