Flora was the goddess of flowers, of flowering plants, of vegetation in its springtime bloom. Her cult was ancient — she had a flamen (the Flamen Floralis, of the lower rank) and a temple on the Quirinal hill — but her great festival, the Floralia (April 28 to May 3), was instituted in 240 BCE on advice of the Sibylline books after a series of bad harvests, and quickly became one of the most popular Roman festivals because of its riotous and licentious character. The Floralia were celebrated with games (the Ludi Florales), with the wearing of bright colors (forbidden at most other festivals), with banquets, and with the appearance on the stage of mime-actresses who performed naked at popular demand — a feature of the festival that scandalized the more austere among the Romans (the elder Cato is said to have left the games in disapproval) but that delighted the populace.
Flora's mythology was sparse. Ovid in the Fasti has her give an account of her own origin — she had been the nymph Chloris, loved by Zephyr the west wind, and given by him eternal dominion over the spring's flowers, with the power to make any flower from any season bloom for the loved or honored. Her narrative beyond this aetiology was minimal.
