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.
Odyssey
Odysseus' protectress, the goddess Athena, requests to Zeus, king of the gods, to finally allow Odysseus to return home when Odysseus' enemy, the god of the sea Poseidon, is absent from Mount Olympus to accept a sacrifice in Ethiopia. Then, disguised as a Taphian chieftain named Mentes, she visits Telemachus to urge him to search for news of his father. He offers her hospitality; they observe the suitors dining rowdily while the bard Phemius performs a narrative poem for them. Penelope objects to Phemius' theme, the "Return from Troy", because it reminds her of her missing husband, but Telemachus rebuts her objections, asserting his role as head of the household.
