Origin: From Cervantes's Don Quixote (1605), in which the self-made knight charges a row of windmills, convinced they are giants, and is thrown from his horse by a turning sail. Madame de Sévigné was already using the windmill image in 1680, and the Académie française listed the phrase in 1835 for fighting imaginary enemies or obstacles. English "tilting at windmills" comes from the same chapter.
