Poseidon was protector of seafarers, and of many Hellenic cities and colonies. In Homer’s Iliad, Poseidon supports the Greeks against the Trojans during the Trojan War. In the Odyssey, during the sea-voyage from Troy back home to Ithaca, the Greek hero Odysseus provokes Poseidon’s fury by blinding his son the Cyclops Polyphemus.
