(M73) The foregoing evidence lends some support to the conjecture—for it is only a conjecture—that the great festival of Osiris at Sais, with its accompanying illumination of the houses, was a night of All Souls, when the ghosts of the dead swarmed in the streets and revisited their old homes, which were lit up to welcome them back again. Herodotus, who briefly describes the festival, omits to mention its date, but we can determine it with some probability from other sources. Thus Plutarch tells us that Osiris was murdered on the seventeenth of the month Athyr, and that the Egyptians accordingly observed mournful rites for four days from the seventeenth of Athyr.(174) Now in the Alexandrian calendar, which Plutarch used, these four days corresponded to the thirteenth, fourteenth, fifteenth, and sixteenth of November, and this date answers exactly to the other indications given by Plutarch, who says that at the time of the festival the Nile was sinking, the north winds dying away, the nights lengthening, and the leaves falling from the trees. During these four days a gilt cow swathed in a black pall was exhibited as an image of Isis. This, no doubt, was the image mentioned by Herodotus in his account of the festival.(175) On the nineteenth day of the month the people went down to the sea, the priests carrying a shrine which contained a golden casket. Into this casket they poured fresh water, and thereupon the spectators raised a shout that Osiris was found. After that they took some vegetable mould, moistened it with water, mixed it with precious spices and incense, and moulded the paste into a small moon-shaped image, which was then robed and ornamented.(176) Thus it appears that the purpose of the ceremonies described by Plutarch was to represent dramatically, first, the search for the dead body of Osiris, and, second, its joyful discovery, followed by the resurrection of the dead god who came to life again in the new image of vegetable mould and spices. Lactantius tells us how on these occasions the priests, with their shaven bodies, beat their breasts and lamented, imitating the sorrowful search of Isis for her lost son Osiris, and how afterwards their sorrow was turned to joy when the jackal-headed god Anubis, or rather a mummer in his stead, produced a small boy, the living representative of the god who was lost and was found.(177) Thus Lactantius regarded Osiris as the son instead of the husband of Isis, and he makes no mention of the image of vegetable mould. It is probable that the boy who figured in the sacred drama played the part, not of Osiris, but of his son Horus;(178) but as the death and resurrection of the god were celebrated in many cities of Egypt, it is also possible that in some places the part of the god come to life was played by a living actor instead of by an image. Another Christian writer describes how the Egyptians, with shorn heads, annually lamented over a buried idol of Osiris, smiting their
