Athena/Pallas

One concept that I have thought about is Athena emerging from the head of Zeus being his literal idea or creation. Also, the another name for Athena is Pallas. This immediately reminds me of Castor and Pollux.

Castor and Pollux were said to be a set of twins that shared a mother but different fathers. There were also two more twins in the egg from which they were born. One was Helen of Troy. Her twin is Clytemnestra.
