In the 20th century this identification was accepted by Thomas P. Stevens, succentor and sacrist, and later honorary canon, of Southwark Cathedral, who wrote a number of guidebooks to the cathedral, and a history that was revised and reprinted many times. He went on to date the foundation of the supposed original nunnery to "about the year 606", although he provided no evidence to support the date. Although recent guidebooks are more circumspect, referring only to "a tradition", an information panel at the east end of the cathedral still claims that there had been "A convent founded in 606 AD" and "A monastery established by St Swithun in the 9th century".
