"These one-eyed giants, although good cheesemakers, are insular; they
have no laws and no sense of community, they are, therefore, vastly
inferior to the civilised world to which Odysseus belongs."
...
"The men come across a cave full of supplies and wait inside for the
owner to return, but when he does, the giant Cyclops closes the cave
entrance with a huge boulder. The monster makes a snack of two men for
dinner and two more again for breakfast. Resourceful Odysseus then
gets the Cyclops drunk on wine and blinds him with a giant pole he has
sharpened. The men are able to escape the grasps of the wounded
monster by tying themselves beneath the bellies of Polyphemus' sheep.
Hurling a rock at Odysseus' ship as it sails away, the Cyclops calls
on his father Poseidon to make sure the heroes never return home
alive."
