In Homer’s Odyssey, Odysseus lands on the Island of the Cyclopes during his journey home from the Trojan War.  The Cyclopes were giants who lived in caves and kept sheep and goats for their milk and cheese.

Odysseus and his men enter the cave of the cyclopes Polyphemus. When the latter returns from the fields and finds the men in his cave, he traps them there, and over the next few days eats six of them.  Odysseus and his remaining men manage to escape Polyphemus, by driving a burning stake into his eye and blinding him. 

Unfortunately for Odysseus, Polyphemus asks his father Poseidon for help exacting revenge.  The latter sends storms and contrary winds down on Odysseus as he sails for home, making his journey considerably more treacherous.
