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.
Pandia
In Greek mythology, the goddess Pandia or Pandeia (, meaning "all brightness") was a daughter of Zeus and the goddess Selene, the Greek personification of the moon. From the "Homeric Hymn to Selene", we have: "Once the Son of Cronos [Zeus] was joined with her [Selene] in love; and she conceived and bare a daughter Pandia, exceeding lovely amongst the deathless gods." An Athenian tradition perhaps made Pandia the wife of Antiochus, the eponymous hero of Antiochis, one of the ten Athenian tribes ("phylai").
