Peter of Goulaion
Peter of Goulaion was a Byzantine abbot of the early 9th century, who was used by Emperor Nikephoros I as envoy.
He was abbot of the monastery of Goulaion, whose exact location and identity are not known. He is commonly identified with the Petrus abbas who was one of the leaders of an embassy sent by Nikephoros I to Charlemagne in 802/3. In 806, during the invasion of Asia Minor by the Abbasid caliph Harun al-Rashid, Peter and Michael, along with Gregory, the steward of Amastris, were sent to the Caliph to propose negotiate a peace.
He may also be identifiable with the unnamed abbot of Goulaion, who according to Theodore Stoudites abandoned the veneration of icons in, but later returned to an iconophile position.
