Garci Rodríguez de Montalvo

Montalvo incorporated a fourth book in the original series, and followed it with a sequel, Las sergas de Esplandián.

At one time Montalvo had the title Alderman of Medina del Campo and was clerk of the land of the surrounding town.

[3] In 1482 he was part of a contingent sent from Medina del Campo to guard Alhama in the Province of Granada, which had recently been captured from the Moors.

[4] Montalvo spent many years translating and recasting the Amadis of Gaul novels and appending a fourth book of his own.

[6][7] The novel was highly influential in motivating Hernán Cortés and other explorers in the discovery of the "island", which they believed lay along the west coast of North America.
