He is first attested as a participant of a synod on 2 March 1166, held at the imperial palace and presided over by Emperor Manuel I Komnenos (r. 1143–1180) in person.
He is listed 15th among the imperial relatives, bearing the high title of sebastos, and with the court offices of oikeios vestiarites and chartoularios.
[2] In 1182, King Béla III of Hungary attacked the Byzantine fortresses of Belgrade and Braničevo.
