Ancient Greeks accepted the Thracian sky god Zeus (Days/light) into their pantheon as the chief god, from whose head supposedly sprang the goddess Athena, yet the Greeks knew that Athena had come from (ice age) Lake Tritonis (southern Tunisia/northeastern Algeria) , named for Triton who was Posidon or his son of that name, the father of Athena, the “goddess” who killed her sister Pallas in mock battle.
