The winter solstice ritual was called Lenaea, the Festival of the Wild Women. In very ancient times, a man representing the harvest god Dionysos was torn to pieces and eaten by a gang of women on this day. Later in the ritual, Dionysos would be reborn as a baby. By classical times, the human sacrifice had been replaced by the killing of a goat. The women’s role had changed to that of funeral mourners and observers of the birth.

Winter solstice celebrations of Christianity, Judaism, Neopaganism, etc

Now that’s my kind of festival, except the human sacrifice part.
