Part 8/10:
The eventual decline of Lupercalia's popularity can be attributed in part to religious reforms enacted by Pope Gelasius in 495 AD, who deemed the festival immoral. In an effort to retain some form of celebration near the date of Lupercalia, the Church established February 14 as St. Valentine's Day. However, this did not signify a direct replacement for Lupercalia; the two observances simply happened to overlap in their timing.
