Excerpt from the book Don Quixote de la Mancha:
"What giants?" said Sancho Panza.
"Those you see there," answered his master, "with the long arms, and some have them nearly two leagues long."
"Look, your worship,'' said Sancho. "What we see there are not giants but windmills, and what seem to be their arms are the vanes that turned by the wind make the millstone go."
"It is easy to see," replied Don Quixote, "that you are not used to this business of adventures. Those are giants, and if you are afraid, away with you out of here and betake yourself to prayer, while I engage them in fierce and unequal combat."
