(fl mid-13th century). English singer. He was one of three Englishmen described by the theorist Anonymous IV as ‘good singers’ of mensural polyphony, who sang with great refinement (‘valde deliciose’). Some time before 1295 he bequeathed a troper to St Paul’s Cathedral, London, where he may have been a canon. Flindell’s contention that he was the 11th/12th-century theorist Johannes Cotto is without foundation. The appellation ‘Filius Dei’ (Godson) may imply that he was a foundling.
