"The Lupercalia ritual in Rome was held in the cave itself. Similar rituals held in other parts of the Empire had to use venues symbolic of the cave on Mount Aventine. Two high-born young men stripped naked and sacrificed a dog and a goat. They smeared blood on their foreheads, then wiped it off with wool dipped in milk. The men made a show of laughing (it being important to be jovial, in both senses) and wrapped strips of the goat's hide about themselves. A great feast was then held ~ perhaps involving the remains of the goat.

Finally each man lead a group of near-naked men around the hills and bounds of Rome. These two colleges of priests were called the Luperci Quinctiales and the Luperci Fabiani ~ Mark Anthony being one of the more famous members. Women would line up to be thwacked by the priests with strips of goat skin (presumably the untanned hide would not have been hard enough to hurt!) The belief was that this would improve their chances of pregnancy."

Well at least it's "traditional" and sounds a lot more fun than a
card from Clintons !
