Jehan de Grieviler

Elizabeth Aubrey argues that since Jehan was a known member of the Puy d'Arras, he cannot be identified with the "Grieviler" of the necrology.

[1] Nonetheless, a further piece of evidence for establishing his chronology are the songs he is known to have composed with Adam de la Halle, who was very young in the 1250s.

Probably Jehan was one of the sixteen unordained married clerics in minor orders who petitioned the Bishop of Arras on 28 January 1254 to exempt them from secular taxation.

Jehan participated in a total of thirty-four jeux partis, initiating six of the exchanges himself.

He also wrote six chansons courtoises, and a seventh attributed to Jehan de la Fontaine may be by him.
