High Quality Content by WIKIPEDIA articles! Peter of Canterbury or Petrus (died c. 607 AD or after 614) was a Benedictine abbot and companion of Augustine in the Gregorian mission to England. He became the first abbot of what would become St Augustine`s Abbey. Augustine sent Peter as an emissary to Rome around 600 to convey news of the mission to Pope Gregory I. Peter`s death has traditionally been dated to around 607, but evidence suggests that he was present at a church council in Paris in 614, so he probably died after that date.
