While some believe that Valentine’s Day is celebrated in the middle of February to commemorate the anniversary of Saint Valentine’s death or burial–which probably occurred around A.D. 270–others claim that the Christian church decided to place St. Valentine’s day in the middle of February in an effort to “Christianize” the pagan celebration of Lupercalia.

Celebrated on February 15, Lupercalia 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 a sacred cave.

The priests would sacrifice a goat, for fertility, and a dog, for purification. They would then strip the goat’s hide into strips, dip them into the sacrificial blood (which explains the touch of red una dey use up and down)

They then ran naked or nearly-naked around Palantine whipping any woman within striking distance with the thongs. Many women welcomed the lashes and even bared their skin to receive the fertility rite; it’s open to speculation what the lashes represented.

During Lupercalia, the men randomly chose a woman’s name from a jar to be coupled with them for the duration of the festival. Often, the couple stayed together until the following year’s festival. Many fell in love and married.
