In the subsequent war, several miracles occur, including flowers sprouting from the lances of the knights.
Another war has Agolant invading south-western France and besieging the city of Agen, but he is forced to retreat to Pampeluna (Pamplona).
Agolant is a central character in the late 12th century Old French chanson de geste Aspremont (before 1190[2]).
Versions of this chanson were extremely popular in England, Italy (see the adaptation by Andrea da Barberino) and even Scandinavia.
[3] Agolant appears in Jean Bagnyon's 15th century La Conqueste du grand roy Charlemagne des Espagnes et les vaillances des douze pairs de France, et aussi celles de Fierabras (book 3, part 1, chapters 4–5), a work largely based on the Historia Caroli Magni, probably known to Bagnyon via the Speculum Historiale of Vincent de Beauvais.
