St. Thomas Cantilupe was Bishop at Hereford from 1275. He was Lord High Treasurer and twice Chancellor of Oxford. He supported Simon de Montfort in his attempts to prevent foreigners taking religious posts in England, and left the country after Simon was defeated. Edward I brought Cantilupe back to become Hereford's Bishop. In 1786 the west end of the Cathedral fell down damaging the Norman nave. Repairs were undertaken by James Wyatt.
