Spanish novels adapted into plays

Don Quixote, the full title being The Ingenious Gentleman Don Quixote of La Mancha, is a Spanish novel by Miguel de Cervantes. It was originally published in two parts, in 1605 and 1615. Considered a founding work of Western literature, it is often said to be the first modern novel. The novel has been labelled by many well-known authors as the "best book of all time" and the "best and most central work in world literature". Don Quixote is also one of the most-translated books in the world and one of the best-selling novels of all time.
