From The Odyssey by Homer
The Cyclops scene, as described in Wikipedia:
After the giant returns in the evening and eats two more of the men, Odysseus offers Polyphemus some strong and undiluted wine given to him earlier on his journey. Drunk and unwary, the giant asks Odysseus his name, promising him a guest-gift if he answers. Odysseus tells him “Οὖτις”, which means “nobody” and Polyphemus promises to eat this “Nobody” last of all. With that, he falls into a drunken sleep. Odysseus had meanwhile hardened a wooden stake in the fire and drives it into Polyphemus’ eye. When Polyphemus shouts for help from his fellow giants, saying that “Nobody” has hurt him, they think Polyphemus is being afflicted by divine power and recommend prayer as the answer.
From a poem by Emily Dickinson:
I’m Nobody! Who are you?
Are you – Nobody – too?
Then there’s a pair of us!
Don’t tell! they’d advertise – you know!
From Through the Looking Glass by Lewis Carroll:
“Just look along the road and tell me if you can see either of them.”
“I see nobody on the road,” said Alice.
“I only wish I had such eyes,” the King remarked in a fretful tone. “To be able to see Nobody! And at that distance, too!”
