Crocodile. “The great reptile of Typhon.” The seat of its “worship” was Crocodilopolis and it was sacred to Set and Sebak—its alleged creators. The primitive Rishis in India, the Manus, and Sons of Brahmâ, are each the progenitors of some animal species, of which he is the alleged “father”; in Egypt, each god was credited with the formation or creation of certain animals which were sacred to him. Crocodiles must have been numerous in Egypt during the early dynasties, if one has to judge by the almost incalculable number of their mummies. Thousands upon thousands have been excavated from the grottoes of Moabdeh, and many a vast necropolis of that Typhonic animal is still left untouched. But the Crocodile was only worshipped where his god and “father” received honours. Typhon (q.v.) had once received such honours and, as Bunsen shows, had been considered a great god. His words are, “ Down to the time of Ramses B.C. 1300, Typhon was one of the most venerated and powerful gods, a god who pours blessings and life on the rulers of Egypt.” As explained elsewhere, Typhon is the material aspect of Osiris. When Typhon, the Quaternary, kills Osiris, the triad or divine Light, and cuts it metaphorically into 14 pieces, and separates himself from the “god”, he incurs the execration of the masses; he becomes the evil god, the storm and hurricane god, the burning sand of the Desert, the constant enemy of the Nile, and the “slayer of the evening beneficent dew”, because Osiris is the ideal Universe, Siva the great Regenerative Force, and Typhon the material portion of it, the evil side of the god, or the Destroying Siva. This is why the crocodile is also partly venerated and partly execrated. The appearance of the crocodile in the Desert, far from the water, prognosticated the happy event of the coming inundation—hence its adoration at Thebes and Ombos. But he destroyed thousands of human and animal beings yearly—hence also the hatred and persecution of the Crocodile at Elephantine and Tentyra.
