Valentine's Day is really an ancient holiday - On February 15, Romans celebrated Luperaclia,
honoring Faunus, god of fertility. Men would go to a grotto dedicated to Lupercal, the wolf god, located at the foot of Palatine Hill and where Romans believed that the founders of
Rome,
Romulus and Remus, were suckled by a she-wolf. The men would sacrifice a goat, don its skin, and run around, hitting women with small whips, an act which was supposed to ensure fertility. In ancient Roman religion and myth, Faunus was the horned god of the forest, plains and fields; when he made cattle fertile he was called Inuus. He came to be equated in literature with the Greek god Pan.
According to one story, Roman emperor Claudius II imposed a ban on marriages because too many young men were dodging the draft by getting married (only single men had to enter the army). A Christian priest named Valentinus was caught performing secret marriages and sentenced to death. While awaiting execution, young lovers visited him with notes about how much better love is than war — the first “valentines.” The execution occurred in 269 CE on February 14th.
