what does odysseus give the cyclops as a gift

In Book IX of The Odyssey, Odysseus gives
the Cyclops (Polyphemus) an ivory bowl full of wine. He tells
Polyphemus that he intended the wine as a gift if Polyphemus would help them off of his island,
but that he now knows that Polyphemus would never help him. Odysseus, always thinking on his
feet, offers two more bowls full of wine (and also nectar and ambrosia) to the
Cyclops who soon passes out drunk. It’s this clever play by Odysseus
that leads to the blinding of the Cyclops and escape from the
island. Keep in mind that it also leads to 10 years of wandering since it is
Polyphemus who appeals to his father Poseidon to plague Odysseus and his
men.
