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.
Agetor
Agetor (Ancient Greek: Ἀγήτωρ), alternatively spelled Hegetor (Greek: ) meaning "Leader" or "Ruler" was an epithet given to several gods of Greek mythology, primarily Zeus in the region of Lacedaemon. The name probably describes Zeus as the ruler of gods, humankind, and the universe in general. Agetor was also an epithet of Apollo. Finally, it was also an epithet applied to Hermes, who conducts the souls of men to the lower world. Under this name Hermes had a statue at Megalopolis.
