The Pagan Book of Days for Friday, January 6th
Twelfth Night/Epiphany of Kore-Persephone/Christian Epiphany
Twelfth Night, when the debris of the Yule feast must be cleared away. In the Julian (Old Style) calendar it is Old Christmas Day. The nocturnal rite in honor of Kore was held overnight 5 to 6 of January in the Korelon at Alexandria. It was a mystic drama preparing the way for Kore/Persephone’s rise into the world.
