Who is Zeus from Theogony and Works and Days and what is their importance?

Zeus is the youngest son of Cronos and Rhea. Earth tricks Cronos into believing a stone wrapped in swaddling clothes is Zeus and Cronos swallows the stone. When Zeus grows older, he rescues his brothers and sisters from Cronos' belly. Zeus sends Pandora to earth to release plagues and evils upon mankind as punishment for accepting the fire. He binds Prometheus to a rock and has an eagle eat his liver every day because Prometheus gives fire to mankind against Zeus' will. This torment ceases only when Heracles rescues Prometheus which Zeus permits to bring honor to his son. Zeus sends Menoetius to Erebus because of his extreme pride. He also releases Obriareus, Cottus and Gyes to help fight against the Titans, who the Olympian gods defeat in battle, and Zeus sends the Titans to a prison at the ends of the earth. Zeus defeats Typhoeus, the son of Earth and Tartarus, and the other gods ask him to rule them and be their king. Zeus is the all-powerful king of the gods who controls lightning and thunder.
