Los Quatro Libros Del Invencible Cavallero Amadis De Gaula
Resumen del Libro

Prose romance of chivalry, possibly Portuguese in origin. The first known version of this work, dating from 1508, was written in Spanish by Garci Ordóñez (or Rodríguez) de Montalvo, who claimed to have corrected and emended corrupt originals. Internal evidence suggests that the Amadís had been in circulation since the early 14th century or even the late 13th. Cf. Encyclopaedia Britannica.
