What part does Zeus play in the odyssey

In The Odyssey, Zeus does not frequently appear; yet, when he does, he certainly utilizes his significant influence. In a sense, Zeus even sets forth the entire plot of The Odyssey, for, after being begged by Athena to assist Odysseus, Zeus offers his permission to intervene in Odysseus's journey. Furthermore, Zeus even makes the promise to help Odysseus return safely.
Zeus also sends a message in the form of an omen to Penelope's suitors. Telemachus pleads with these inconsiderate suitors to leave his home in the name of Zeus; of course, when they refuse, Zeus sends forth a pair of eagles that fight and tear at each other violently. The suitors struggle to understand what this vague message means, while the prophet Halitherses properly interprets the omen as a sign of Odysseus's inevitable return.
