Tradition. The 363 founding date and the founder's story come from later tradition. The monastery is well attested from the late antique and medieval period on.

This hilltop monastery of the Syriac Orthodox Church is traditionally said to have been founded in the 4th century by the hermit Mattai, who fled persecution in the Roman empire. It became a major center of West Syriac learning in Persian territory and kept an important manuscript library. It is still active.
