"Don Quixote" is the sword in the stone of high school Spanish classes worldwide. In this novel, a noble named (guess who) Don Quixote decides that being an old-timey knight would be awesome. Everyone thinks he's crazy since he's a few hundred years too late for the feudal system.
He ends up going on various absurd quests and finally confuses a windmill with a giant and fights it to death (his death, not the windmill's).
Plus, a character says, "Thou hast seen nothing yet." The book was written in Spanish, meaning a translator amazingly put that sentence together.
The book explores a lot of philosophical themes that probably interested the Olympia Academy's young men.
