 Cicero seems to make Selene responsible for Endymion's sleep, so that "she might kiss him while sleeping".From Pausanias we hear that Selene was supposed to have had by Endymion fifty daughters, who possibly represented the fifty lunar months of the Olympiad.Nonnus has Selene and Endymion as the parents of the beautiful Narcissus, but in other accounts, including Ovid's "Metamorphoses", Narcissus was the son of Cephissus and Liriope.
