Richard of Cirencester (Latin: Ricardus de Cirencestria; before 1340–1400) was a cleric and minor historian of the Benedictine abbey at Westminster.
[3] His only known extant work are the four books of the Historial Mirror of the Deeds of the Kings of England (Latin: Speculum historiale de gestis regum Angliae), covering the years from 447 to 1066.
[4] At the conclusion of the fourth book Richard expresses his intention of continuing his narrative from the accession of William I, and incorporating a sketch of the Conqueror's career from his birth.
Besides the Historial Mirror Richard also wrote, according to a 1396 letter from William of Woodford to Archbishop Thomas of Canterbury,[6] a treatise on the offices (De officiis) and there was formerly in the cathedral library at Peterborough another tract ascribed to him entitled Super Symbolum.
It was then published under a variant of his name (Ricardus Corinensis)[7][8] and the conflation was universally accepted, to the point where Richard's name is more associated with the discredited forgery than with his own works.
