Serlo

Serlo (died c. 1148) was a medieval abbot of Cirencester Abbey in England as well as Dean of Salisbury.

Serlo was a canon of Salisbury Cathedral.

Prior to becoming abbot he was dean of the cathedral chapter at Salisbury, appearing in documents twice as that official – once around 1116 and once in 1121. He resigned that office to become a canon at Merton Priory, where he was named in 1125 as previously dean at Salisbury. Serlo probably moved to Merton to keep an eye on the interests of Roger of Salisbury, the Bishop of Salisbury, who was instrumental in securing royal grants of privileges for the newly founded Augustinian house. His death was remembered at Salisbury on 30 January, where he was listed as "Serlo decanus Sarum et postea abbas Cirencestriae", or "Serlo, dean of Salisbury and afterwards abbot of Cirencester". It is not clear if Roger of Salisbury acted as a patron to Serlo's career, but the historian A. F. Wareham thinks this is likely.
