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.

In Montalvo's version, Amadís was the most handsome, upright, and valiant of knights. The story of his incredible feats of arms, in which he is never defeated, was interwoven with that of his love for Oriana, daughter of Lisuarte, king of England; she was his constant inspiration, and eventually he won her in marriage.

Many characters in the Amadís were based on figures from Celtic romance, and the work was, indeed, Arthurian (Arthurian legend) in spirit. It differed, however, from the Arthurian cycle in numerous important respects. There was no particular sense of place or time, only a vague unspecified field for the interplay of idealized human relationships. Whereas earlier romance had reflected a feudal society, the Amadís invested the monarchy with an authority that heralds the advent of absolutism. Amadís himself was more idealized and therefore less human than such earlier heroes as Lancelot and Tristan. He was also far more chaste: French romance had already put a courtly veneer over the disruptive eroticism of the Celtic tales, but, with the Amadís, medieval chivalry achieved complete respectability.

The work and its exaltation of new standards of knightly conduct caught the imagination of polite society all over Europe. In France, especially, it became the textbook of chivalresque deportment and epistolary style. Throughout the 16th century, numerous sequels and feeble imitations appeared, the fashion being given its deathblow by parody early in the 17th century in Miguel de Cervantes' novel Don Quixote (though Cervantes held the original in high esteem). The first English adaptation of the Amadís appeared in 1567; the best English translation is an abridged version by the poet Robert Southey, first published in 1803.
