Founding  Mor Timothy Mosa Alshamany (2015), Archbishop of the monastery Mor Mattai Monastery

The monastery was founded in 363 AD by Mor Mattai the Hermit who fled persecution in Amid under the Roman Emperor Julian the Apostate with 25 other monks and took residence in Mount Alfaf.[1] According to Syriac tradition, he converted Mor Behnam to Christianity and healed his sister, Sarah, whom he converted too. Their father, Sennacherib, was the Governor of the area of Nimrud, and appointed by the Persian King Shapur. He killed his son and daughter when he learned they became Christians, but he later recanted and built a church and a monastery per Mor Mattai's request on the Mount Alfaf.[1]

The church and monastery were surrounded by a strong wall and contained water tanks. The monks that came with Mor Mattai lived in huts and caves around the monastery and on the mountain itself. Mor Mattai became the monastery superior and under his leadership the community developed a true monastic ethos. When Mor Mattai died, he was interred in the monastery.[1] He was succeeded by Mor Zakai, one of the monks who came with him from Amid.

12th–16th centuries

In the 12th century, after storming a nunnery in Khudida, Kurds attacked the monastery for four months with 1,000 horsemen and foot soldiers. The monks burnt the ladders to prevent their entry. The Kurds rolled two large boulders against the walls from above, breaking a hole through which the Kurds tried to force entrance. The monks successfully fought back with stones and darts before repairing the walls. Abbot Abu Nser, the monastery superior, lost an eye in this battle. Eventually, the Kurds were bribed with gold and silver from the churches and retreated, since they were afraid of a Mongol attack.[2]

In 1171, neighboring Kurds led several attacks on the monastery and were repelled by a coalition of monks and local Christians. The Kurds promised the monks they would cease their attacks and paid them 30 dinars; believing their monastery would be safe, the monks sent the local Christians back to their villages. Later, a force of 1,500 Kurds pillaged the monastery and killed 15 monks who could not find refuge in the upper citadel. The monks who survived the attack abandoned the monastery and relocated to Mosul. Upon hearing of the attack, the governor of Mosul attacked the Kurds, killing many; in retaliation the Kurds destroyed nine Assyrian villages, killing their inhabitants and attacked the Monastery of Mar Sergius.[3]

In 1369, another Kurdish attack on the monastery damaged many manuscripts. During the 19th century, Kurds looted the monastery numerous times.[4]

20th century–current

The monastery is currently maintained by the Syriac Orthodox Church and serves the small farming villages below it. Every year, Christians of various church denominations gather in the monastery on September 18 to commemorate the day of Mor Mattai's death.[5]
