This is off-topic, but I was curious how Zeus and Endymion were related and did a quick search.

Zeus had taken Enydmion to Olympus, to live with the gods. Endymion saw and fell in love with Hera, Zeus' wife and consort. Endymion was determined to seduce or the goddess. Zeus discovered the impetuous mortal's plan. Endymion thought he was making love to Hera, when he was actually having sex with a phantom, made out of cloud. Catching Endymion in the act, Zeus then cast Endymion out of Olympus, and into Hades.
