In St Luke's Chapel, behind the altar is a late 14th century painting, known as the Despenser Retable, named after the Bishop of Norwich, Henry le Despenser (1369–1406). During the Peasants' Revolt of 1381, Despenser's forces successfully contained the revolt in Norfolk and the painting was probably commissioned in thanksgiving. Shield in the border of the painting are associated with others who led the attack on the peasants. The retable was re-discovered in 1847, having been reversed and used as a table top.
