It's Saint Valentine's Day, the day dedicated to all lovers, and the traditional time for Witches around the world to practice all forms of love magic and love divination.
This day is sacred to Juno-Lupa, the she-wolf goddess of the ancient Roman religion. In early times she was honored annually on this day by a women's fertility festival and the sacrifice of a female wolf.
And Regarding the Saint Valentine himself, well, could anything be more pagan than Cupid?
However, there were three lads the church has tried to paste on the Cupid celebration, none took, and so another pagan celebration survives.
