 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 Cubières.After killing a shepherd, he had to leave Cubières and became a shepherd himself, and, in due course, a parfait.
