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.
Odyssey
Odysseus' protectress, the goddess Athena, requests to Zeus, king of the gods, to finally allow Odysseus to return home when Odysseus' enemy, the god of the sea Poseidon, is absent from Mount Olympus to accept a sacrifice in Ethiopia. Then, disguised as a Taphian chieftain named Mentes, she visits Telemachus to urge him to search for news of his father. He offers her hospitality; they observe the suitors dining rowdily while the bard Phemius performs a narrative poem for them. Penelope objects to Phemius' theme, the "Return from Troy", because it reminds her of her missing husband, but Telemachus rebuts her objections, asserting his role as head of the household.
