A strange blending of primitive beliefs occurred when the deities were given astral forms. As has been shown (Chapter III) gods were supposed to die annually. The Egyptian priests pointed out to Herodotus the grave of Osiris and also his star. There are "giants' graves" also in those countries in which the gods were simply ferocious giants. A god might assume various forms; he might take the form of an insect, like Indra, and hide in a plant, or become a mouse, or a serpent, like the gods of Erech in the Gilgamesh epic. The further theory that a god could exist in various forms at one and the same time suggests that it had its origin among a people who accepted the idea of a personal god while yet in the stage of Naturalism. In Egypt Osiris, for instance, was the moon, which came as a beautiful child each month and was devoured as the wasting "old moon" by the demon Set; he was the young god who was slain in his prime each year; he was at once the father, husband, and son of Isis; he was the Patriarch who reigned over men and became the Judge of the Dead; he was the earth spirit, he was the bisexual Nile spirit, he was the spring sun; he was the Apis bull of Memphis, and the ram of Mendes; he was the reigning Pharaoh. In his fusion with Ra, who was threefold--Khepera, Ra, and Tum--he died each day as an old man; he appeared in heaven at night as the constellation Orion, which was his ghost, or was, perhaps, rather the Sumerian Zi, the spiritual essence of life. Osiris, who resembled Tammuz, a god of many forms also, was addressed as follows in one of the Isis chants: There proceedeth from thee the strong Orion in heaven at evening, at the resting of every day! Lo it is I (Isis), at the approach of the Sothis (Sirius) period, who doth watch for him (the child Osiris), Nor will I leave off watching for him; for that which proceedeth from thee (the living Osiris) is revered. An emanation from thee causeth life to gods and men, reptiles and animals, and they live by means thereof. Come thou to us from thy chamber, in the day when thy soul begetteth emanations,-- The day when offerings upon offerings are made to thy spirit, which causeth the gods and men likewise to live.[309]
