Don Quixote is a classic Spanish novel that follows the adventures of Alonso Quixano, a man so obsessed with chivalric tales that he loses touch with reality and sets out to become a knight-errant named Don Quixote. With his loyal but practical squire, Sancho Panza, he roams the countryside seeking to revive knightly ideals and right imagined wrongs—most famously mistaking windmills for giants.
