Christ with St Thomas and St Christopher:These two paintings were in the chapel of St Blaise, a small chapel in the southern section of the south transept which survived until the 18th century. They had been obscured by two monuments (now re-located) and were only discovered during cleaning in 1934. By 1936 figures of the Risen Christ with St Thomas and St Christopher bearing the Christ Child on his shoulder had been revealed. The main figures are nine feet (three metres) in height. The Incredulity of St Thomas is painted on a vermilion ground, diapered with fleurs de lys which were once gold, as was the vexillum, or cross, that Christ holds in his left hand. With his right he grasps the hand of the kneeling St Thomas to put it against the wound in his side. Christ wears a pink coloured mantle and the Apostle wears a pale yellow tunic and dark green over-mantle. No inscription remains. St Christopher is painted on a green ground, originally diapered with small rosettes. The saint has his mantle drawn over his head and carries his staff in his right hand while he holds the Child on his shoulder, supporting the foot in his hand. The Child wears a blue robe and carries an apple. In the water through which the saint is wading there is a small head, which may represent a mermaid associated with his legend. Two Latin inscriptions remain. These can be translated: "Think that St Christopher was so called because he carried Christ. The Omnipotent makes grow the One whom he is carrying" and at the base "Whoever keeps safe the image of St Christopher is surely possessed by no exhaustion on that day". Both saints were revered by Henry III. The paintings are in oil on a thin primed ground and have been attributed to Master Walter of Durham, the King's Painter. Dates from 1270-1300 have been suggested for the paintings. The rosettes carved around the arches also have traces of colour.
