[3] At the end of the eleventh century, the region had come under control of the Armenian Kogh Vasil, whose wife, together with a vassal of Kogh, Kurtig, seems to have evicted the Syriac monks and granted it to Armenian monks.
The monastery later also became the burial place of Kogh Vasil and became associated with the dynastic identity of the ruling house.
[4][5] The monastery became with Ark'akaghin, Drazark and Skevra a famous center of manrousoumn, the study of church songs, melodies and khaz notation.
[6] Both the later Catholicoi Grigor III Pahlavuni and Nerses IV Snorhali were educated at the monastery by the abbot Step'anos Manuk (Stephen the Boy).
[7] The monastery was burned down by the Danishmendid ruler Melik Mehmed Gazi in 1136.
