Goddess and embodiment of the Moon 

 

Roman Name: Luna

 

Lover of Endymion, a mortal.  Having learned that loving a mortal can only result in heartbreak when he grows old and dies, she begs Zeus to grant him eternal youth . . . and eternal slumber.  (see relief below)

 

Note: While Artemis has dominion over the Moon, Selene is the Moon incarnate. The Greek goddess Selene is pronounced "Seh-lee-nee" while Selene DiSilva, protagonist of The Immortals,  pronounces her name "Celine."
