Osmund of Salisbury

Osmund was a Norman noble and clergyman who accompanied William the Conqueror to England in 1066. He was appointed as the Lord Chancellor of England around 1070 and was involved in many civil affairs, including the compilation of the Domesday Book. He was also the second bishop of Salisbury, or Old Sarum, and was responsible for building the cathedral there and establishing a cathedral body with a dean, precentor, chancellor, treasurer, and canons. He also introduced the Sarum Rite, a liturgical variation of the Roman Rite that was widely used in England until the Reformation. He died on 3 or 4 December 1099 and was buried at Old Sarum. His remains were later transferred to New Salisbury in 1457 and placed in a shrine in the Lady Chapel. He was canonized by Pope Callixtus III in 1457 and his feast day is celebrated on 4 December by the Catholic Church and the Church of England. He is regarded as the patron saint of insanity, mental illness, paralysed people, ruptures, and toothache.
