Robert of Bath

Robert or sometimes Robert of Lewes (died 1166) was a medieval English Bishop of Bath.

Robert was a native of England, but his ancestry was Flemish, probably of noble birth. His birthdate and when he became a monk are not known. He was a Cluniac and a monk of Lewes Priory and a protégé of Henry of Blois who employed him at Glastonbury Abbey on administrative tasks. He may have been the prior of Winchester Cathedral but there is no certain evidence of this, as it is based on an appearance of a "Robert, prior of Winchester" on the 1130 Pipe Roll, and a 15th-century historian. He was named Bishop of Bath through the influence of Henry of Blois, and was consecrated probably in March 1136.

Robert was instrumental in reorganizing his diocese as well as building and restoring at Wells. He was the bishop that organized the archdeacons of the diocese on a territorial basis. He was considered pious as well as a man of business. He also built at Bath, and gave borough status to the town of Wells. He also reorganized the church at Wells, which had previously been the cathedral for the diocese prior to John of Tours moving the episcopal seat to Bath.

In 1138, during Robert of Gloucester's rising against King Stephen of England, the bishop was in charge of the defenses of Bath. He captured Geoffrey Talbot, who was a supporter of Robert of Gloucester's, but when he went out to parley with another group of Gloucester's supporters, the bishop was captured even though he had been offered a safe conduct for the parley. The bishop was then exchanged for Geoffrey Talbot. In 1141 he was at the gathering where Henry of Blois changed allegiance to the Empress Matilda at Winchester.

The bishop died 31 August 1166 and was buried in Bath Cathedral before the high altar. He may have been the author of the Gesta Stephani, an identification first made by the historian R. H. C. Davis in 1962. While it is not certain that Robert was the author, the outlook of the work certainly fits with the known outlook of Robert.
