 Other events included in this history include a papal visit from Leo III and the damage from the Normans in 846 and 882.Writing in 1900, Otto Opperman, a scholar in Germany, proved that this chronicle is a false history, concocted by Oliver Legipont, a Benedictine Monk residing at Great St. Martin’s in 1730.Other theories, including one that suggests the Church was built in Frankish times (during the 5th to 9th centuries) are similarly unsupported by evidence and likely apocryphal.
