Assisted by Vestal Virgins, the Luperci (male priests) conducted purification rites by sacrificing goats and a dog in the Lupercal cave on Palatine Hill, where the Romans believed the twins Romulus and Remus had been sheltered and nursed by a she-wolf before they eventually founded Rome. Clothed in loincloths made from sacrificed goats and smeared in their blood, the Luperci would run about Rome, striking women with februa, thongs made from skins of the sacrificed goats. The Luperci believed that the floggings purified women and guaranteed their fertility and ease of childbirth. February derives from februa or “means of purification.”
