Richart de Semilli (floruit late 12th or early 13th century) was a trouvère, probably from Paris, which he mentions three times in his extant works.
These number ten in one chansonnier (with a few also copied into related manuscripts), and one anonymous song, "L’une est la chastelaine, devers Mont le Heri", which has sometimes been attributed to him by modern scholars, but of which most of the first strophe and music are missing.
Unusually for a trouvère, Richart used the same poetic structure and melody for his "Chancon ferai plein d’ire et de pensee" and "Je chevauchai l’autrier la matinee", and also for "De chanter m’est pris courage" and "Quant la sesons renouvele".
This last piece, along with "Molt ai chanté, riens ne m’i puet valoir" and "Nous venions l’autrier de joer", each use variations of the last melodic lines three times.
"Chancon ferai" and "L’autrier tous seus chevauchoie mon chemin" are rotrouenges.
