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.
Henotheism
While Greek and Roman religion began as polytheism, during the Classical period, under the influence of philosophy, differing conceptions emerged. Often Zeus (or Jupiter) was considered the supreme, all-powerful and all-knowing, king and father of the Olympian gods. According to Maijastina Kahlos "monotheism was pervasive in the educated circles in Late Antiquity" and "all divinities were interpreted as aspects, particles or epithets of one supreme God". Maximus Tyrius (2nd century A.D.) stated: "In such a mighty contest, sedition and discord, you will see one according law and assertion in all the earth, that there is one god, the king and father of all things, and many gods, sons of god, ruling together with him."
