Zeus
Zeus played a dominant role, presiding over the Greek Olympian pantheon. He fathered many of the heroes and was featured in many of their local cults. Though the Homeric "cloud collector" was the god of the sky and thunder like his Near-Eastern counterparts, he was also the supreme cultural artifact; in some senses, he was the embodiment of Greek religious beliefs and the archetypal Greek deity.
Anu
According to Walter Burkert, an expert on ancient Greek religion, direct parallels also exist between Anu and the Greek god Zeus. In particular, the scene from Tablet VI of the "Epic of Gilgamesh" in which Ishtar comes before Anu after being rejected by Gilgamesh and complains to her mother Antu, but is mildly rebuked by Anu, is directly paralleled by a scene from Book V of the "Iliad". In this scene, Aphrodite, the later Greek development of Ishtar, is wounded by the Greek hero Diomedes while trying to save her son Aeneas. She flees to Mount Olympus, where she cries to her mother Dione, is mocked by her sister Athena, and is mildly rebuked by her father Zeus. Not only is the narrative parallel significant, but so is the fact that Dione's name is a feminization of Zeus's own, just as "Antu" is a feminine form of "Anu". Dione does not appear throughout the rest of the "Iliad", in which Zeus's consort is instead the goddess Hera. Burkert therefore concludes that "Dione" is clearly a calque of Antu.
