Career
He was burned at the stake in 1321, as a result of the Inquisition at Pamiers led by Jacques Fournier (afterwards Pope Benedict XII). Much of Bélibaste"s biography can be found in the pages of Emmanuel Le Roy Ladurie"s Montaillou. Although Bélibaste never lived at Montaillou, he is frequently mentioned in the interrogations of suspected heretics from Montaillou.
He was the son and namesake of Guillaume Bélibaste, a rich farmer at Cubièresearch
After killing a shepherd, he had to leave Cubières and became a shepherd himself, and, in due course, a parfait. Others migrated regularly between the two regions.
One of the latter was Pierre Maury, a native of Montaillou. When, in 1320, his lover, Raymonde Piquier, became pregnant, Bélibaste persuaded Pierre Maury to marry her.
Then, a few days later, he dissolved the marriage and salvaged his own reputation by making it appear the child was Maury"son
Eventually he was betrayed by the spy Arnaud Sicre in the service of the Inquisition. Bélibaste was taken to Villerouge Termenes and burnt at the stake there.
