And there are those who fashion ears and eyes of costly material, and consecrate them, dedicating them in the temples to the gods—by this plainly indicating that God sees and hears all things. Besides, the lion is with them the symbol of strength and prowess, as the ox clearly is of the earth itself, and husbandry and food, and the horse of fortitude and confidence; while, on the other hand, the sphinx, of strength combined with intelligence—as it had a body entirely that of a lion, and the face of a man. Similarly to these, to indicate intelligence, and memory, and power, and art, a man is sculptured in the temples. And in what is called among them the Komasiæ of the gods, they carry about golden images—two dogs, one hawk, and one ibis; and the four figures of the images they call four letters. For the dogs are symbols of the two hemispheres, which, as it were, go round and keep watch; the hawk, of the sun, for it is fiery and destructive (so they attribute pestilential diseases to the sun); the ibis, of the moon, likening the shady parts to that which is dark in plumage, and the luminous to the light. And some will have it that by the dogs are meant the tropics, which guard and watch the sun’s passage to the south and north. The hawk signifies the equinoctial line, which is high and parched with heat, as the ibis the ecliptic. For the ibis seems, above other animals, to have furnished to the Egyptians the first rudiments of the invention of number and measure, as the oblique line did of circles.
