English mason. He worked at Caernarfon Castle, Wales, in the first years of C14, and was in charge of important repairs at Clarendon Palace (1316–17) before building a great tower at Pontefract Castle, Yorks. (1323–6). He was engaged in building at Spalding Priory, Lincs., from c.1328, and seems to have remained there for the rest of his life. He was versatile, being engaged in architectural work for military, civil, and ecclesiastical buildings. He probably began his career carrying out construction at the Benedictine Abbey of Eynsham, Oxon., in the early 1290s, hence his surname.
