Painting on a wine cup (kylix), dating to 550 B.C., now in the British
Museum, London. The scene shows the birth of Athena from Zeus’s
head. After having defeated the Titans, Zeus had as his first wife the
goddess Metis, daughter of Oceanus, who personified wisdom and cunning
intelligence, and was the one who “of the gods and mortal human
beings knows the most” (Hesiod, Theogony, 887). But, according
to a prophecy, Zeus knew that the child generated with Metis should
become wiser and more powerful than his father: so he decided to swallow
his spouse. In this way, the supreme god of Olympus acquired for himself
the qualities of Metis: wisdom and ruse. From Metis, who was pregnant
when she was swallowed, Athena was born. She came out, fully armed,
from the head of Zeus, opened with a stroke of Hephaestus’s ax.
Athena was a very ancient divinity, perhaps worshiped since the Bronze
Age, as a goddess of war and of the arts. In particular, she was regarded
as the protectress of the city of Athens, where, on the Acropolis, was
the great temple dedicated to her as the Virgin Goddess, the Parthenon.
The goddess’s attribute of Parthenos, “Virgin”,
was not a reference to the physical integrity of the woman but to the
social condition of young woman in marriageable age (as opposed to gyne,
the married woman) (Dowden 1989, p. 2).
