Odysseus believes one of the suitors, Amphinomus, is blameless. Unfortunately, the Cyclops is the sea god Poseidon's son; Odysseus has engaged a formidable enemy.
When the epic opens, Telemachus is at a loss as to how to deal with the suitors who have taken over his home and seek the hand of his mother in marriage for primarily political reasons.
