Odysseus had received numerous gifts from Maron (or Maro), grandson of Dionysus and Ariadne and priest of Apollo, at Ismarus.
"Then I ordered the rest of my loyal friends to stay there and guard the ship, while I selected the twelve best men and went forward. I took with me a goatskin filled with dark sweet wine that Maron, son of Euanthes, priest of Apollo guardian god of Ismarus, had given me, because out of respect we protected him, his wife and child. He offered me splendid gifts, seven talents of well-wrought gold, and a silver mixing-bowl: and wine, twelve jars in all, sweet unmixed wine, a divine draught."
Odysseus went on to describe the sweet, unmixed wine as incredibly strong. Maron would mix 1 part wine with 20 parts water when he served it. Odysseus filled a large goatskin with the wine, sensing that the Cyclops would have a great thirst. Since the wine was so strong undiluted, the Cyclops became incredibly intoxicated when he consumed it; this helped Odysseus and his men gain the upper hand when the Cyclops (Polyphemus) was passed out in a drunken stupor. Odysseus stabbed Polyphemus in the eye and escaped to his ship with his remaining men on the underbellies of sheep.
Thanks to Maron's gift of wine, Odysseus and (most of) his men were able to escape the island of the cyclopes.
