Durand of Huesca
Durand of Huesca (c. 1160 – 1224) was a Spanish Waldensian, who converted in 1207 to Catholicism. He became a Catholic theologian, author of a Liber Antihaeresis against the Cathars, which is considered perhaps the best primary source on early Waldensian thought. He is attributed a role in founding the Poor Catholics, a preaching order and precursor of later mendicant orders.
