Lawrence Durdin-Robertson reported in his Perpetual Calendar of the Fellowship of Isis an excerpt from Martin A. Larson’s scholarly work, Religion of the Occident, (Philosophical Library, 1959). Larson writes: “… it usually began on October 31st … On the two days following, the portions of Osiris were found, reconstituted, and resurrected. This was the central element in the myth, for if Osiris could regain life and become immortal through the power of Isis, then all her devotees could do the same.”
