in Roman religion, wicked and fearsome spectres of the dead. Appearing in grotesque and terrifying forms, they were said to haunt their living relatives and cause them injury. To propitiate these ghosts and keep them from the household, ritual observances called Lemuria were held yearly on May 9, 11, and 13. These Lemuria, reputedly instituted by Romulus in expiation of his brother's murder, required the father of every family to rise at midnight, purify his hands, toss black beans for the spirits to gather, and recite entreaties for the spirits' departure.
