Resumen de Julian of Toledo and Don Yllán de Toledo:

E. Michael Gerli

• Exemplum XI of Don Juan Manuel’s Libro del Conde Lucanor (“De lo que contesçió a un deán de Sanctiago con don Yllán, el grand maestro de Toledo”, ca. 1331‒1335) relates the encounter of Don Yllán de Toledo, a learnèd necromancer, and the ambitious Dean of the Cathedral of Santiago de Compostela. Exemplum XI is one of the best known and most celebrated stories in the book for its seemingly preternatural turn in the plot’s action and the characters’ visit to the Other World. The article seeks to identify Don Yllán with Archbishop Julian of Toledo (642‒690), author of the Prognosticon futuri saeculi (687), an important theological tract that circulated widely during the Middle Ages and that served as the basis for the doctrine of Purgatory. The Prognosticon contains illustrative anecdotes of dialogs with the dead and journeys to and from the Other World. As such, it endowed Julian with the legendary reputation of necromancer and probably served as inspiration for Don Juan Manuel’s Exemplum XI of El Conde Lucanor.
