What did Odysseus sacrifice to Poseidon?

Odysseus did not explicitly sacrifice anything to Poseidon; rather, he incurred the god's wrath by blinding his son, the Cyclops Polyphemus. In response, Poseidon made Odysseus's journey home to Ithaca perilous and prolonged. To appease Poseidon, Odysseus ultimately vowed to make sacrifices upon his return, including a grand offering of a ram, a bull, and a great black ship.
