He is the addressee of the poem Robert du Chastel, biaus sire, a jeu parti by another trouvère of Arras, Jehan Bretel (died 1272), which was judged by another Artesian, Gaidifer d'Avion.
En loial amour ai mis is designated coronée (crowned) in one source, indicating that it won a poetic contest, probably to be associated with the Puy d'Arras.
[2] The later anonymous religious piece La volontés dont mes cuers est ravis was a contrafactum of its melody.
Besides these two songs Robert wrote Amours me mont me guerroie, Bien ait l'amours qui m'a doné l'usage, Nus fins amans ne se doit esmaier, and Pour (çou) ce se j'ain et je ne sui amés.
This last was quoted—both lyrically and to a lesser degree musically—by Guillaume de Machaut in his four-part Middle French motet.
