The moon belonged to Diana, and was her car; the sun, in like manner, to Apollo, though he did not drive the car himself, but Helios, the sun-god, did.  The world was thought to be a flat plate, with Delphi in the middle, and the ocean all round.  In the far east the lady dawn, Aurora, or Eôs, opened the gates with her rosy fingers, and out came the golden car of the sun, with glorious white horses driven by Helios, attended by the Hours strewing dew and flowers.  It passed over the arch of the heavens to the ocean again on the west, and there Aurora met it again in fair colours, took out the horses, and let them feed.  Aurora had married a man named Tithonus.  She gave him ambrosia, which made him immortal, but she could not keep him from growing old, so he became smaller and smaller, till he dwindled into a grasshopper, and at last only his voice was to be heard chirping at sunrise and sunset.
