Plutarch, De Iside et Osiride
Goodwin, Ed.

But those who join with these physiological accounts certain mathematical matters relating to astronomy suppose Typhon to mean the world of the sun, and Osiris that of the moon; for that the moon, being endued with a prolific and moistening light, is very favorable both to the [p. 102] breeding of animals and the springing up of plants; but the sun, having in it an immoderate and excessive fire, burns and dries up such things as grow up and look green, and by its scorching heat renders a great part of the world wholly uninhabitable, and very often gets the better of the moon. For which reason the Egyptians always call Typhon Seth, which in their language signifies a domineering and compelling power. And they tell us in their mythology, that Hercules is placed in the sun and rides about the world in it, and that Hermes doth the like in the moon. For the operations of the moon seem to resemble reason and to proceed from wisdom, but those of the sun to be like unto strokes effected by violence and mere strength. But the Stoics affirm the sun to be kindled and fed by the sea, and the moon by the waters of springs and pools, which send up a sweet and soft exhalation to it.
