Roman festival noted

This is late, given that Valentines Day was last week, but it sounds so odd it's worth noting anyway:

For centuries before Christianity came on the scene, the Romans celebrated a mid-February fertility festival called Lupercalia. (It continued to be honored until the 4th century A.D.) This odd ritual involved a cadre of nearly naked male runners, who roamed the city, lightly whipping every nubile female in sight with bloody strips of goathide. Sounds suspiciously like S&M, but it was a purification ritual. The floggings cleansed the city and chased off evil spirits, making Rome’s women receptive in the most basic sense for procreative sex.
