Austorc de Segret

Austorc de Segret or Austau de Segret (fl. 1270) was an Auvergnat troubadour with only one surviving sirventes, "No sai quim so, tan sui desconoissens".
Written in a rime mimicking that of the Italian troubadour Sordello's "Aitant ses plus viu hom quan viu jauzens", Austorc's sirventes is almost a planh for Louis IX of France, who died in 1270 on the Eighth Crusade. Besides lamenting Louis, the troubadour laments the defeat suffered by the Crusaders against the "Saracens, Turks, and Arabs". He concludes that either God or the Satan is misleading Christians: there is no other possible explanation for the power of the Muslims. But among the humans Austorc is nonetheless willing to excoriate for the failed Crusade is Louis's brother Charles of Anjou, the caps e guitz (head and guide)—in Austorc's words—of the infidels because he convinced Louis to attack Tunis, not the Holy Land, and he immediately negotiated a peace with the Muslims after Louis's death.
