So while we don’t really celebrate the religious aspects of the holiday we do cook a ham, make some southern style potato salad and feast a bit.
But Ishtar (Pronounce it like E-star) was the goddess of fertility, love, sex and war in ancient Assyrian and Babylonian cultures.
Plus there are the pagan symbols inherent in the celebration, the rabbit, the chicks, eggs, etc. All fertility symbols.
So the Catholic church, never one to pass up an opportunity to co-opt ritual, stole it.
