Master-mason, and presumably architect, of Amiens Cathedral from 1220. He started the nave, and was succeeded (c.1235) by Thomas de Cormont, who designed the west front and the upper parts of the nave. In turn, he was succeeded by his son, Regnault de Cormont (master-mason c. 1240–88), who was responsible for the choir above the tribune, crossing-vault, and transept elevations, all in the Rayonnant style of Gothic.
