Endymion, the name of Selene Goddess Of The Moon Costume, translates to "Diver." Selene, the moon, can be seen as hugging her diver when she rises, similar to how the sun sets before diving into the sea. The convergence of the two lovers leads to their embrace via the union of nature. Endymion is a mortal, yet he never ages or dies, allowing Selene to have him.
