Thibaut de Blaison  Thibaut de Blaison, Blason, or Blazon (died after March 1229) was a Poitevin nobleman, Crusader, and trouvère from a noble family with lands in Blason and Mirabeau. Eleven poems—one contested and one definitely spurious—have been ascribed to Thibaut in the chansonniers. Three further anonymous songs have also been attributed to him by Terence H. Newcombe, his modern editor. Thibaut was the seneschal of Poitou and his uncle was Maurice, Bishop of Poitiers. In 1214 Thibaut helped negotiate a truce between Philip II of France and John of England. In 1212 he was taking part in the Reconquista in Spain and he was among the Albigensian Crusaders besieging Toulouse in 1218. He appears alongside the trouvère Amauri de Craon in a document of 1219. He attended the coronation of Louis IX in 1226, along with the trouvère Hue de la Ferté. Theobald I of Navarre, also a trouvère, dedicated the song "De ma dame souvenir" to Thibaut and also used Thibaut's "Amours, que porra devenir" as a model for a religious poem of his own. Gautier d'Espinal also borrowed the melody of "Amours" for one piece. Thibaut himself borrowed from rhythms from the polyphonic repertoire of the day. He may have based his "Bien font Amours lor talent" on the "conductus" "Quid frustra consumeris" and "Chanter et renvoisier seuil" on "Sol sub nube latuit". With the exception of three "chansons" that are restricted to a sixth—"Amours, que porra devenir", "Chanter et renvoisier seuil", and "Huimain par un ajourant"—and one, "Li miens chanters ne puet mais remanoir", which is severely restricted in movement, most of Thibaut's melodies move freely. They are all basically syllabic, with only "Li miens chanters" exhibiting more complex melisma. Compared to his melodies (all recorded in bar form), his prosody is usually simple, though three songs—"Bien font Amours lor talent", "Bon jour ait hui cele a cui sui amis", and "Quant je voi esté venir"—exhibit some variety.
