The character Don Quijote de la Mancha, also known as the gentleman of the sad figure, is central to Miguel de Cervantes Saavedra's narrative in "The Ingenious Knight Don Quixote of la Mancha." He embodies the ideals of chivalry while facing the harsh realities of a world that has largely moved on from those romantic notions. His aspirations and delusions lead him on a series of comical adventures that challenge both his identity and the perception of heroism.
