His name also appears in a Reading manuscript including the rota "Sumer is icumen in", and on one of seven sets of four-part compositions in the Wintonia collection.
Over 40 settings have been identified in several sources, a group of compositions almost equal in size to that of Léonin, the earlier composer of the continental Notre Dame school, but only one of the 40 can be restored completely; the others exist only in fragments.
Some of his work appears in the Worcester Fragments, a collection of 59 manuscript leaves representing about a third of the total surviving polyphony from 13th-century England.
Stylistically they are similar to the Reading Rota itself ("Sumer is icumen in"), emphasizing tonic and supertonic, and showing the English preference for the harmonic interval of the third.
