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.
Apesantius
Apesantius () was an epithet of the god Zeus from Greek mythology, under which he had a temple on Mount Apesas (modern Mount Phoukas) near Nemea, where Perseus was said to have first offered sacrifices to him.
