First published in Valencia in 1490, some consider it the first modern novel in Europe.

Miguel de Cervantes in the book burning scene of Don Quixote considers it the best chivalry novel. Martorell was a chivalrous man and suffered an early death due to court intrigue, leading to a colleague, Martí Joan de Galba, finishing the novel.
