The tale was probably of Oriental origin, and introduced to the West by way of Byzantium. It found its way into French literature through the medium of Latin, as the names Amicus and Amelius indicate, and was eventually attached to the Carolingian cycle in the 12th-century chanson de geste of Amis et Amiles. This poem is written in decasyllabic assonanced verse, each stanza being terminated by a short line. It belongs to the heroic period of French epic, containing some passages of great beauty, notably the episode of the slaying of the children, and maintains a high level of poetry throughout.
Amis has married Lubias and become count of Blaives (Blaye), while Amiles has become seneschal at the court of Charlemagne, and is seduced by the emperor's daughter, Bellisant. The lovers are betrayed, and Amiles is unable to find the necessary supporters to enable him to clear himself by the ordeal of single combat, and fears, moreover, to fight in a false cause. He is granted a reprieve, and goes in search of Amis, who engages to personate him in the combat. He thus saves his friend, but in so doing perjures himself. Then follows the leprosy of Amis, and, after a lapse of years, his discovery of Amiles and cure. There are obvious reminiscences in this story of Damon and Pythias, and of the classical instances of sacrifice at the divine command. The legend of Amis and Amiles occurs in many forms with slight variations, the names and positions of the friends being sometimes reversed. The crown of martyrdom was not lacking, for Amis and Amiles were slain by Ogier the Dane at Novara on their way home from a pilgrimage to the Holy Land.
The versions of Amis and Amiles include:
e) Walter Pater's retelling of the story in the first chapter of his Studies in the History of the Renaissance (1873), 'Two Early French Stories.'
