Moses was born to an
Assyrian family in Qaluq, a village in the region of Ṣawro near
Mardin, the son of a priest named Isaac. At the age of eight, he was
bitten by a snake, which caused the loss of his right thumb and left his index finger permanently crooked.
Mission to Europe Patriarch
Ignatius Abdullah I bar Stephanos sent Moses to Europe with
Syriac New Testament manuscripts and letters of recommendation, likely due to the patriarch's open attitudes toward communion, or at least positive
ecumenical dialogue, with the
Catholic Church. He arrived in
Rome sometime before 1549 and was granted an audience with
Pope Paul III. Paul sent him back to Mardin with a letter to the
patriarch who then dispatched Moses again to Rome, this time with his confession of faith. By then Paul had died, so Moses presented the confession to his successor,
Pope Julius III. in southeastern

Ethiopian monastery of San Stefano near the
Vatican, where he befriended the monk Taṣfa Ṣejon (
Petrus Aethiops) and worked on a
Syriac translation of the
Latin liturgy. He studied
Latin and
Italian while teaching
Syriac, and came into contact with prominent
orientalists including
Guillaume Postel,
Andreas Masius, and
Johann Albrecht Widmanstetter. Moses also demonstrated a basic knowledge of
Ethiopic. He reports that when he was in Rome, he saw with his own eyes "the
mandila which was sent by our
Lord to
Abgar", specifying that it was located in the
Church of the Apostles Peter and Paul; this is in reference to the
Doctrine of Addai. Moses sought to establish a Syriac printing press in Rome, securing partial financial backing from then-Cardinal and Vatican librarian
Marcello Cervini, who gave him 13 gold
scudi; however, the support proved inadequate to fully realize the printing project. In addition to his priestly status being doubted, Moses left Rome, arriving in northern
Germany with one of the NT Syriac manuscripts where he partnered with
Widmanstetter, who had long been interested in
Syriac studies. Widmanstetter, who had been charged by
Teseo Ambrogio to study Syriac, "the language hallowed by the blessed lips of
Christ", managed to get Moses an audience with
Ferdinand,
King of Hungary and Bohemia, who supported the projected and led the two to produce the first printed Syriac New Testament in
Vienna in 1555. In
Austria, Emperor Ferdinand granted him a
coat of arms, a gift Moses excitedly reported to Masius. He also expressed hope that Europe would defeat the
Ottoman Empire, which he saw as divine justice against
Turkish domination. Moses resided in the
Jesuit hall at in Vienna. monastery of
Mor Hananyo in
Tur Abdin Moses provided models for the type, drawing each
Serṭo character in his elegant handwriting for the engravers, who engraved the
typeface for the
press based on his handwriting. The
colophon is dated September 27, 1555. About 1,000 copies were printed: 500 for Europe, 300 for the
Syriac Orthodox and
Maronite patriarchs, and 200 for Moses, who distributed them to various
Eastern churches, including the
patriarch of the
Church of the East. While
Dolabani later claimed that copies were kept at the
Mor Hananyo Monastery near Mardin, none have been found; they may have been moved to the Church of the
Forty Martyrs nearby. The edition circulated widely.
Azariah dei Rossi utilized this works for clarifying what he perceived as corrupt or obscure passages in the New Testament
Vulgate, particularly those containing
Aramaic expressions. To support his argument, he analyzed seventeen Gospel passages with Aramaic words, presenting each first in the Latin Vulgate, then in Syriac (using
Serṭo script and
cursive Hebrew and Latin transcription), and finally in his own
Italian translation. Dei Rossi primarily used
Teseo Ambrogio degli Albonesi’s Introductio as a resource for learning Syriac, which he viewed as merely a different alphabet for writing Aramaic, while also referencing Widmanstetter’s
Elementa. Some editions included the entire
New Testament, while others contained only the
Gospels, sometimes accompanied by Widmanstetter’s
Elementa (1555–56), a Syriac
primer. On his return journey to Mardin, Moses sold copies along the way, including in
Famagusta, Cyprus, in October 1556. Moses accompanied Patriarch
Ignatius Niʿmatallah I (1557–1576) on his flight from
Mesopotamia to Rome, undertaken due to increasing
persecution of Christians by the Muslims in the
Ottoman Empire. In Rome, they met
Pope Gregory XIII (1572–1585), where Moses assisted his patriarch in communicating with the
Italians. From 1581 to 1585, Moses taught Arabic and Syriac at the
Collegio dei Neofiti in
Rome. He continued to teach Syriac, serving as a tutor to Andreas Masius and other humanists, and maintained correspondence in Syriac with Masius. Moses returned to Mardin around 1556, where he continued copying manuscripts, including finishing his copy of the
Chronicle of Michael the Great (now lost, but the copy Moses made underlies the only surviving witness). He also copied and translated numerous works, including
Syriac liturgical texts, biblical books, philosophical works (such as
Aristotle via
Jacob of Edessa), and other historical chronicles besides Michael's. Several manuscripts copied by Moses survive, including Harley MS 5512 (
British Library), containing parts of the Roman Missal in
Serṭo with
Syriac anaphoras, written for the
Ethiopian convent in Rome. '', where Moses spent much of his time in the
Vatican Moses is last recorded in Rome in 1578, accompanying Patriarch Niʿmatallah to the
papal court. He copied manuscripts in the 1580s and is thought to have died in or shortly after 1592, possibly in Rome. == Claims of excommunication and defrocking ==
