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.
Meilichios
Zeus tended to obscure the earlier figure he had supplanted. However, while bearing the name 'Zeus', Zeus Olympios, the great king of the gods, noticeably differs from the Zeus Meilichios, a decidedly Chthonian character, often portrayed as a snake, and as seen beforehand, they cannot be different manifestations of the same god, in fact whenever 'another Zeus' is mentioned, this always refers to Hades. Zeus Meilichios and Zeus Eubouleus are often referred to being alternate names for Hades.
