The Gaelic Maundeville (Author: John Maundeville)

paragraph 130

Trebizond is a good city, and therein is the body of Athanasius who made the psalm (creed) Quicunque vult. The Greek Emperor put a good lord of his household to keep that city against the Turks, and that lord went into rebellion against the Greek Emperor, and called himself Emperor of Trebizond, and thenceforward that city with its lordship is apart from the Greeks.
