Library Plutarch Of Isis and Osiris
Chapter 34
§34: They believe also that the sun and moon do not go in chariots, but sail about the world
34. They believe also that the sun and moon do not go in chariots, but sail about the world perpetually in certain boats; hinting hereby at their feeding upon and springing first out of moisture. They are likewise of the opinion that Homer (as well as Thales) had been instructed by the Egyptians, which made him affirm water to be the spring and first original of all things; for that Oceanus is the same with Osiris, and Tethys with Isis, so named from τίτθη, _a nurse_, because she is the mother and nurse of all things. For the Grecians call the emission of the genital humor ἀπουσία, and carnal knowledge συνουσία: they also call a son υἱός, from ὕδωρ, _water_, and ὗσαι, _to wet_; and likewise Bacchus ὕης, _the wetter_, they looking upon him as the lord of the humid nature, he being no other than Osiris. For Hellanicus hath set him down Hysiris, affirming that he heard him so pronounced by the priests; for so he hath written the name of this God all along in his history, and that, in my opinion, not without good reason, derived as well from his nature as his invention.
