St Mellitus, third Archbishop of Canterbury, was sent to England in AD 601 by Pope Gregory in response to an appeal from St Augustine of Canterbury for new missionaries. He was chosen by Augustine to be Bishop of the See of London in AD 604, and the Church of St Paul was founded as its Cathedral. Upon the death of St Laurentius, second Archbishop of Canterbury, in AD 619, St Mellitus succeeded to the Archbishopric until he died in AD 624.
