there is no evidence that he had the slightest knowledge of the details of the original African Legend of these gods as it was known to the Egyptians, say, under the VIth Dynasty. Moreover, he never realized that the characteristics and attributes of both Isis and Osiris changed several times during the long history of Egypt, and that a thousand years before he lived the Egyptians themselves had forgotten what the original form of the legend was. They preserved a number of ceremonies, and performed very carefully all the details of an ancient ritual at the annual commemoration festival of Osiris which was held in November and December, but the evidence of the texts makes it quite clear that the meaning and symbolism of nearly all the details were unknown alike to priests and people. An important modification of the cult of Isis and Osiris took place in the third century before Christ, when the Ptolemies began to consolidate their rule in Egypt. A form of religion which would be acceptable both to Egyptians and Greeks had to be provided, and this was produced by modifying the characteristics of Osiris and calling him Sarapis, and identifying him with the Greek Pluto. To Isis were added many of the attributes of the great Greek goddesses, and into her worship were introduced "mysteries" derived from non-Egyptian cults, which made it acceptable to the people everywhere. Had a high priest of Osiris who lived at Abydos under the XVIIIth Dynasty witnessed the celebration of the great festival of Isis and Osiris in any large town in the first century before Christ, it is tolerably certain that he would have regarded it as a lengthy act of worship of strange gods, in which there appeared, here and there, ceremonies and phrases which reminded him of the ancient Abydos ritual. When the form of the cult of Isis and Osiris introduced by the Ptolemies into Egypt extended to the great cities of Greece and Italy, still further modifications took place in it, and the characters of Isis and Osiris were still further changed. By degrees Osiris came to be regarded as the god of death pure and simple, or as the personification of Death, and he ceased to be regarded as the great protecting ancestral spirit, and the all- powerful protecting Father of his people. As the importance of Osiris declined that of Isis grew, and men came to regard her as the great Mother-goddess of the world. The priests described from tradition the great facts of her life according to the Egyptian legends, how she had been a loving and devoted wife, how she had gone forth after her husband's murder by Set to seek for his body, how she had found it and brought it home, how she revivified it by her spells and had union with Osiris and conceived by him, and how in due course she brought forth her son, in pain and sorrow and loneliness in the Swamps of the Delta, and how she reared him and watched over him until he was old enough to
