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.
Euhemerus
Euhemerus refers to a rational island utopia. The ancient Hellenic tradition of a distant Golden Age, of Hesiod's depiction of human happiness before the gift of Pandora, of the mythic convention of idealized Hyperboreans, made concrete in the legendary figure of the Scythian philosopher-hero Anacharsis, or the idealized "Meropes" of Theopompus had been recently enriched by contacts with India. Euhemerus apparently systematized a method of interpreting the popular myths, which was consistent with the attempts of Hellenistic culture to explain traditional religious beliefs in terms of a naturalism. Euhemerus asserted that the Greek gods originally had been kings, heroes, and conquerors, or benefactors to the people, who had thus earned a claim to the veneration of their subjects. According to him, for example, Zeus was a king of Crete, who had been a great conqueror; the tomb of Zeus was shown to visitors near Knossos, perhaps engendering or enhancing among the traditionalists the reputation of Cretans as liars.
