Saint Mellitus (died April 24 624) was the first Bishop of London of the present diocese (established in 604) and the third Archbishop of Canterbury. Bede describes Mellitus as being of noble birth ("Hist. Eccl.", II, vii) and Pope Gregory I describes him as an abbot ("Letters", xi, 54, 59). He may have been abbot of the monastery of St. Andrew on the Celian Hill, founded by Gregory, to which both Gregory belonged before he became pope and St. Wikipedia
