The cyclops loved himself a good meal of human meat. He ate many a people.
Once, a young man came to the island to kill the cyclops.
The cyclops had, to say the least, a lot of trouble killing the young fellow.
At one point the cyclops asked, in his rage: Who are you?
The man replied: I’m nobody.
And the cyclops believed him.
And from that point on, the cyclops had no trouble eating for the rest of his life.
For whenever weary travelers came to the foot of his cave, he could welcome them in happily, reassuring them that “He’s eaten nobody”.
