"Do you see over yonder, friend Sancho, [those] hulking giants? I intend to do battle with them and slay them . . .for this is a righteous war, and the removal of so foul a brood from off the face of the earth is a service God will bless."
"Take care, sir," cried Sancho. "Those over there are not giants, but windmills."
—Miguel de Cervantes, Don Quixote, 160
