Nor is Clavileño what it seems at first sight. A simple wooden horse involves Don Quixote and Sancho in an unexpected adventure. Clavileño the Swift is a flying wooden horse, and its flight is controlled by a peg in its forehead. It appears one night in the duke and duchess’s garden, carried by four savages dressed in ivy green. When they leave it on the ground, one of them says: “Let the knight who has heart for it mount this machine!” It is mounted by Don Quixote and Sancho, the latter reluctantly as he is terrified.
