The wall paintings date from the 14th century and have had much conservation attention. They depict various saints and stories from the Bible. On the north wall can be found St Michael weighing souls, St Christopher, St Anthony with his pig, and St Martin on horseback. Displayed on the south wall are the marriage feast at Cana and the Annunciation. The painting of St Dunstan holding the devil by the nose is the only one of this saint to be found in an English church.
The paintings also include a local saint, St Thomas of Cantelupe. You will find him to the West of the North doorway, in a scene as a little portrait of him as a knight. St Thomas was a Barton man (although Hambleden in Buckinghamshire also claims him) who went on to be Bishop of Hereford, Chancellor of Oxford and High Chancellor of England in the mid 13th century. He died in Italy, and was canonised by Pope John XXII in 1320. In the wall painting only the barest outlines of his face remain, but little villagers surround his feet, holding onto his robes.
The description of the wall paintings on the Cambridgeshire Churches website is worth reading, being both entertaining and informative.
