The Ingenious Gentleman Don Quixote of La Mancha is a Spanish novel by Miguel de Cervantes. Published in two parts, in 1605 and 1615, Don Quixote is the most influential work of literature from the Spanish Golden Age and the entire Spanish literary canon. A founding work of Western literature, it is often labeled "the first modern novel" and is sometimes considered the best literary work ever written.
Alonso Quixano, the protagonist of the novel (though he is not given this name until much later in the book), is a Hidalgo (member of the lesser Spanish nobility), nearing 50 years of age, living in an unnamed section of La Mancha with his niece and housekeeper, as well as a boy who is never heard of again after the first chapter. Although Quixano is usually a rational man, in keeping with the humoral physiology theory of the time, not sleeping adequately - because he was reading - has caused his brain to dry; Quixano's temperament is thus choleric, the hot and dry humor. As a result, he is easily given to anger and believes every word of these fictional books of chivalry to be true.
