What objects does Don Quixote famously mistake for giants?

Don Quixote famously mistakes windmills for giants. The episode occurs during his second outing, when he sees a group of windmills across the plain and charges them as monstrous enemies.

Sancho Panza immediately points out that the supposed giants are windmills, with sails turning in the wind. Don Quixote refuses to accept the explanation, claiming that an enchanter has changed the giants into machines to rob him of glory. He attacks one, and its sail catches his lance and throws both horse and rider to the ground.

The scene captures the novel’s central tension between imagination and reality. Don Quixote interprets ordinary objects through the conventions of the chivalric books he has read, while Sancho usually sees the practical world more clearly. The windmill episode later inspired the expression “tilting at windmills,” meaning fighting imaginary or impossible enemies.

The event is often associated with the windmills of Campo de Criptana in La Mancha, though other Spanish locations, including Consuegra, also claim connections with the literary scene. The important point in the novel is that the objects are windmills, not wine skins, lions, or sheep.
