Jehan de Grieviler
Jehan de Grieviler ("fl." mid- to late 13th century) was an Artesian cleric and trouvère. Jehan was probably born at Grévillers near Arras. A certain "Grieviler" is mentioned in the necrology ("registre") of the Confrérie des jongleurs et des bourgeois d'Arras under 1254. 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. More recent work on these institutions by Carol Symes has suggested they were in fact the same. 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. They were evidently involved in trade and commerce. Jehan participated in a total of thirty-four "jeux partis", initiating six of the exchanges himself. Twenty-eight of these were with Jehan Bretel. Three of these last have surviving melodies, probably composed by him. He also wrote six "chansons courtoises", and a seventh  attributed to Jehan de la Fontaine may be by him. He also composed one surviving "rotrouenge". All of his melodies are conventional, save "Uns pensers jolis", which is through-composed, and "Jolie amours qui m'a en sa baillie", which begins on B and ranges from high to low F.
