English master-mason responsible for part of the rebuilding of the Gothic Lincoln Cathedral from 1192. He was possibly a Norman who acquired his trade in France and settled in Lincoln. The vault of St Hugh's Choir (1192-1200), by him, is probably the first case in Gothic Europe where the emphasis was on decorative rather than structural ribs, and he was perhaps also responsible for the three-dimensional blind overlaid arcading on the walls of St Hugh's Choir. However, Richard the Mason (active 1190s) was also involved, and the original design of the Gothic Cathedral may be his. //
