The Sea Peoples were, in my humble opinion, the people that Odysseus met in Scheria who helped him return to Ithaca. It is said that some Greek
goddess, after the Phaeacians of Scheria gave Odysseus a passage home to Ithaca, turned their ship into stone and it sank. I interpret this as a
metaphor for the ship having failed to return to Scheria. I make a tentative guess that the Phaeacians saw the cause of the disappearance of their
ship as an attack by either the people of Ithaca or a neighboring civilization.
