What is "gavaudan"

Gavaudan (fl. c. 11951215, known in 1212–1213) was a troubadour and hired soldier (soudadier) at the courts of both Raymond V and Raymond VI of Toulouse and later on in Castile. He was from Gévaudan, as his name (probably a nickname) implies. He wrote moralising lyrics, either religious or political, and ten of his works survive, including five sirventes, two pastorelas, one canso, one planh for an anonymous domna (lady), and one Crusade song. He is sometimes clumped in a primitive Marcabrunian "school" of poetry alongside Bernart Marti, Bernart de Venzac, and Peire d'Alvernhe. He developed a hermetic style, combining elements of the trobar ric and trobar clus.
