In the ancient “pagan” world, this 3-day event also began on October 31st. The holiday was called the Isia and the Finding of Osiris. On the 3rd day of the Isia came the most pivotal event in Isis-Osiris theology: Osiris was resurrected from the dead by Isis, making this a very significant day to our ancestors, and a sort of Egyptian Easter! “Arise my love,” she said to him, just as the Judeo-Christian God (or perhaps Mary Magdalene!) said to Jesus in his tomb on the 3rd day.
