Mar Mattai, also called Dayro d-Mor Matay and Dayr Mar Matta, is a Syriac Orthodox monastery on Mount Alfaf, or Jabal Maqlub, northeast of Mosul. Its history includes monastic learning, church leadership, periods of abandonment and the preservation of manuscripts.
The founder and the limits of the foundation date
George A. Kiraz identifies the founder as a monk from the Amid region in the later fourth century and places the monastery’s documentary attestation in the late fifth or early sixth century. [1] The commonly repeated year 363 belongs to the foundation tradition. Mesopotamia’s heritage survey explains its association with Matthew’s flight from persecution and the hagiographic stories of Behnam and Sarah, while noting scholarly questions about those narratives. [2] These traditions explain devotion to the site; the documentary evidence supplies a separate historical chronology.
A monastery with regional church authority
Kiraz describes an early bishopric, local synods and a powerful relationship with the Maphrian of the East, a senior Syriac Orthodox church office. The monastery sometimes served as the Maphrian’s seat. Its burial sanctuary contains the remains of Bar Hebraeus and other church leaders. [1]
Manuscripts, raids and interrupted occupation
Kiraz records Kurdish attacks in 1171 and 1369 that damaged manuscripts, and early nineteenth-century raids followed by twelve years of abandonment. [1] Mesopotamia’s April 2017 field documentation also describes the mountain complex’s churches, memorial spaces and nearby hermit caves. [2] The present buildings are the outcome of many interventions over a long institutional history.
What modern preservation projects document
The Syriac Orthodox Patriarchate’s Department of Syriac Studies lists digitization of 266 Mor Matta manuscripts under the collection identifier DMMM as completed. It separately lists cataloguing as a long-term project. [3] That distinction matters: making manuscript photographs and producing detailed descriptions are different stages of preservation. The project total identifies a digitization undertaking; it is not a count of every manuscript once held by the medieval library.
Older photographs and research access
Hill Museum & Manuscript Library’s account of Arthur Vööbus’s work names Mar Mattai among the libraries he visited. He photographed manuscripts on film during decades of research travel. HMML’s digitization and cataloguing make parts of that wider photographic archive available for study, while acknowledging gaps in the dates and identification of some material. [4] Such records help researchers compare surviving texts and their earlier condition.
A continuing religious community
Mesopotamia’s 2017 survey reported that the advance of ISIS in 2014 was stopped in the valley and that displaced villagers had temporarily sheltered at the monastery. [2] A SyriacPress report dated 18 September 2025 describes the saint’s-day gathering of residents from Bashiqa and Bahzani and a liturgy led by Metropolitan Timotheus Mousa al-Shamani. [5] These dated accounts document refuge, worship and participation by neighbouring communities.
