According to one Greek myth, Pisces represents the fish, sometimes represented by koi fish, into which Aphrodite (also considered Venus) and her son Eros (also considered Cupid) transformed in order to escape the monster Typhon. Typhon, the "father of all monsters," had been sent by Gaia to attack the gods, which led Pan to warn the others before himself changing into a goat-fish and jumping into the Euphrates. A similar myth, one in which the fish "Pisces" carry Aphrodite and her son out of danger, is resounded in Manilius' five volume poetic work "Astronomica": "Venus ow'd her safety to their Shape." Another myth is that an egg fell into the Euphrates river. It was then rolled to the shore by fish. Doves sat on the egg until it hatched, out from which came Aphrodite. As a sign of gratitude towards the fish, Aphrodite put the fish into the night sky. Because of these myths, the Pisces constellation was also known as "Venus et Cupido," "Venus Syria cum Cupidine," "Venus cum Adone," "Dione" and "Veneris Mater," the latter being the formal Latin term for mother.
