By 1400, the Monastery followed the rule of the House of Ewostatewos (Ancient Greek: Εὐστάθιος Eustáthios), and a gadl (hagiography) of Ewostatewos was later composed there.[1] According to Tom Killion, it remained independent of the Ethiopian Church,[2] while Richard Pankhurst states that it continued to be dependent on the Ethiopian Orthodox Tewahedo Church centered in Axum.[3] In either case, a charter survives of the Emperor Zara Yaqob in which he granted lands to Debre Bizen.[4]
