Porphyry
The second appearance of the moon is held sacred in the city of Apollo: and its symbol is a man with a hawk-like face, subduing with a hunting-spear Typhon in the likeness of a hippopotamus. The image is white in colour, the whiteness representing the illumination of the moon, and the hawk-like face the fact that it derives light and breath from the sun. For the hawk they consecrate to the sun, and make it their symbol of light and breath, because of its swift motion, and its soaring up on high, where the light is. And the hippopotamus represents the Western sky, because of its swallowing up into itself the stars which traverse it.
