When, considering the sacred bull of antiquity, the symbol of the fecundating force in nature, Osiris, the national sun-god of the Egyptians, was referred to as distinguished from the Semitic Seth (Set), who was identified with the detested shepherd race. The association of Osiris with Khem shows his Phallic character,[151] and, in fact, Plutarch asserts that he was everywhere represented with the phallus exposed.[152] The Phallic idea enters, moreover, into the character of all the chief Egyptian deities. Bunsen says: “The mythological system obviously proceeded from ‘the concealed god’ Ammon to the creating god. The latter appears first of all as the generative power of nature in the Phallic god Khem, who is afterwards merged in Ammon-ra. Then sprung up the idea of the creative power in Kneph. He forms the divine limbs of Osiris (the primeval soul) in contradiction to Ptah, who as the strictly demiurgic principle, forms the visible world. Neith is the creative principle, as nature represented under a feminine form. Finally, her son Ra, Helios, appears as the last of the series, in the character of father and nourisher of terrestrial beings. It is he, whom an ancient monument represents as the demiurgic principle, creating the mundane egg.”[153] The name of Ammon has led to the notion that he was an embodiment of the idea of wisdom. He certainly was distinguished by having the human form, but his hieroglyphical symbol of the _obelisk_, and his connection with Khem, show his true nature. He undoubtedly represented the primitive idea of a generative god, probably at a time when this notion of fecundity had not yet been extended to nature as distinguished from man, and thus he would form a point of contact between the later Egyptian sun-gods and the pillar gods of the Semites and Phœnicians.[154] To the Egyptians, as to these other peoples, the sun became the great source of deity. His fecundating warmth or his fiery destroying heat were, however, not the only attributes deified. These were the most important, but the Egyptians, especially, made gods out of many of the solar characters,[155] although the association of the idea of “intellect” with Amun-re must have been of late date, if the original nature of Amun was what has been above suggested.
