Month
Rome in May
Fields & crops
Hay was cut, barley harvested in warm places, beans threshed, and vines and young crops weeded and hoed per Columella 11.2. Sheep were washed and sheared.
Courts & law
A busy legal season. Romans avoided marrying in May, which was considered unlucky, especially before the Ides per Ovid, Fasti 5.490.
Senate & politics
Senate and assemblies met normally. The temple of Mercury, dedicated on the Ides of May, was the seat of an early guild of merchants per Livy 2.27; on that day traders sprinkled their goods with water from his spring to wash away the month's lies per Ovid, Fasti 5.663–92.
Military
Full campaigning season: armies marched and supply convoys used good roads and calm seas.
Festivals & religion
Floralia ended on 3 May; the Lemuria (9, 11, 13 May) drove ghosts from the house at midnight with black beans; the Argei, rush puppets, were thrown into the Tiber on 14 or 15 May per Ovid, Fasti 5.
Daily life
Late spring was a time of hard field labour and fresh food: beans, greens and the first barley. Enslaved farm workers, often chained in the ergastulum on large estates, did the heaviest work per Columella 1.6–8, who advises on their supervision. In the city, the Floralia's games included mimes and, by tradition, performers who undressed at the crowd's demand per Valerius Maximus and Lactantius; hostile or late sources. Childbirth was a major risk for women at any season; inscriptions record many deaths of young mothers per surviving epitaphs.
