By this time Horus had reached manhood, and Osiris, returning from the Duat, where he reigned as king of the dead, encouraged him to avenge the wrongs of his parents. Horus thereupon did battle with Set, the victory falling now to one, now to the other. At one time Set was taken captive by his enemy and given into the custody of Isis, but the latter, to her son's amazement and indignation, set him at liberty. So angry was Horus that he tore the crown from his mother's head. Thoth, however, gave her a helmet in the shape of a cow's head. Another version states that Horus cut off his mother's head, which Thoth, the maker of magic, stuck on again in the form of a cow's. Horus and Set, it is said, still do battle with one another, yet victory has fallen to neither. When Horus shall have vanquished his enemy, Osiris will return to earth and reign once more as king in Egypt. Sir J.G. Frazer on Osiris From the particulars of this myth Sir J. G. Frazer has argued[5] that Osiris was "one of those personifications of vegetation whose annual death and resurrection have been celebrated in so many lands"--that he was a god of vegetation analogous to Adonis and Attis. "The general similarity of the myth and ritual of Osiris to those of Adonis and Attis," says Sir J.G. Frazer, "is obvious. In all three cases we see a god whose untimely and violent death is mourned by a loving goddess and annually celebrated by his worshippers. The character of Osiris as a deity of vegetation is brought out by the legend that he was the first to teach men the use of corn, and by the custom of beginning his annual festival with the tillage of the ground. He is said also to have introduced the cultivation of the vine. In one of the chambers dedicated to Osiris in the great temple of Isis at Philæ the dead body of Osiris is represented with stalks of corn springing from it, and a priest is depicted watering the stalks from a pitcher which he holds in his hand. The accompanying legend sets forth that 'this is the form of him whom one may not name, Osiris of the mysteries, who springs from the returning waters.' It would seem impossible to devise a more graphic way of depicting Osiris as a personification of the corn; while the inscription attached to the picture proves that this personification was the kernel of the mysteries of the god, the innermost secret that was only revealed to the initiated. In estimating the mythical character of Osiris, very great weight must be given to this monument. The story that his mangled remains were scattered up and down the land may be a mythical way of expressing either the sowing or the winnowing of the grain. The latter interpretation is supported by the tale that Isis placed the severed limbs of Osiris on a corn-sieve. Or the legend may be a reminiscence of the custom of slaying a human victim as a representative of the corn-spirit, and distributing his flesh or scattering his ashes over the fields to fertilize them."
