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 (Marvel Comics)
The comic version of Zeus is based on the god of the same name from Greek mythology. Zeus first appears in "Venus" #5 (June 1949), and was adapted by Stan Lee and Jack Kirby.
