In ancient Rome, February was the official beginning of spring and was considered a time for purification. Houses were ritually cleansed by sweeping them out and then sprinkling salt and a type of wheat called spelt throughout their interiors. Lupercalia, which began at the ides of February, February 15, was a fertility festival dedicated to Faunus, the Roman god of agriculture, as well as to the Roman founders Romulus and Remus.
To begin the festival, members of the Luperci, an order of Roman priests, would gather at the sacred cave where the infants Romulus and Remus, the founders of Rome, were believed to have been cared for by a she-wolf or lupa. The priests would then sacrifice a goat, for fertility, and a dog, for purification.
The boys then sliced the goat’s hide into strips, dipped them in the sacrificial blood and took to the streets, gently slapping both women and fields of crops with the goathide strips. Far from being fearful, Roman women welcomed being touched with the hides because it was believed the strips would make them more fertile in the coming year. Later in the day, according to legend, all the young women in the city would place their names in a big urn. The city’s bachelors would then each choose a name out of the urn and become paired for the year with his chosen woman. These matches often ended in marriage. Pope Gelasius declared February 14 St. Valentine’s Day around 498 A.D. The Roman “lottery” system for romantic pairing was deemed un-Christian and outlawed.
