He was a favorite of Henry III, Duke of Brabant, and he remained at court for some time after the death of his patron in 1261.
[1] In 1269 he entered the service of Guy de Dampierre, afterwards count of Flanders, probably as roi des ménestrels, and followed him in the next year on the abortive crusade in Tunis in which Louis IX lost his life.
The expedition returned by way of Sicily and Italy, and Adenet has left in his poems some very exact descriptions of the places through which he passed.
He seems, however, to have remained in the service of Count Guy, although he made frequent visits to Paris to consult the annals preserved in the Abbey of St.
[2]A document attests a gift to him in 1297 of a golden buckle from King Edward I, and that is the last information available about Adenet.
