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
In addition to the Panhellenic titles and conceptions listed above, local cults maintained their own idiosyncratic ideas about the king of gods and men. With the epithet Zeus Aetnaeus he was worshiped on Mount Aetna, where there was a statue of him, and a local festival called the Aetnaea in his honor. Other examples are listed below. As Zeus Aeneius or Zeus Aenesius, he was worshiped in the island of Cephalonia, where he had a temple on Mount Aenos.
