Florentius of Peterborough was a seventh-century saint and martyr.
[1][2] Florentius was a Roman, and is known to history mainly through the hagiography of the Secgan Manuscript.
[3] According to the Anglo-Saxon Chronicle manuscript E, Florentius' relics were purchased from Bonneval Abbey[4] and moved to Peterborough Cathedral in 1013 or 1016 by Abbot Ælfsi of Peterborough.
[5] Florentius' was venerated at Peterborough along with Cyneswith[6] and Cyniburg.
However, his feast day on 27 September might suggest that he was in reality Florentinus of Sedun, who was martyred by the Vandal persecution.
