The White Bull
The story is based on the Greek mythological tale of Europa and the bull, where the white bull is the king of the Greek gods, Zeus, in disguise. Zeus, the sky and thunder god of the Olympic pantheon, often wore a disguise when romantically pursuing mortal women, so as to avoid the eye of his wife and sister, Hera.
Zeus (DC Comics)
Zeus' origins and early history mostly conform to the way they are presented in classical mythology. He is a child of the Titans Cronus and Rhea and leader of the twelve Olympian Gods. During a war between the Titans and Olympians, Zeus slays his father and assumes his place as King of the Gods, ruling from Mount Olympus with his sister-wife Hera. He is the father of numerous gods and heroes, the most famous being Hercules.
