Are there any instances of defying a prophecy? In Greek mythology, there are many prophecies. Usually, in spite of someone's effort to prevent it, what is prophesized still happens. As far as I'm aware, the only one to successfully avoid a prophecy was Zeus. He swallowed Metis and their son was never born, therefore he couldn't overthrow Zeus. Are there any instances in Greek mythology of successfully defying a prophecy?

In the Odyssey, Alcinous, who according to Homer was king of the Phaeacians, receives a prophecy that if he were to sail home from Troy with Odysseus (which he did), his kingdom would come to fall by the wrath of Poseidon. Homer never mentioned the fall of the kingdom. In addition, that particular part of the Odyssey was later edited by Aristophanes of Byzantium to say that Zeus intervened to stop the prophecy.
