Clarified Data on the Written Heritage of Simeon the Persecuted: On the Problem of the Composition and Authorship of the «Fifth Collection» of Isaac the Syrian. A Detailed Inventory of the Ms Dominican Friars of Mosul 907: Observations and Comments

   The purpose of this publication is to clarify the data on the written heritage of the Nestorian monk Simon the Persecuted (13^th–14^th c.) based on a new manuscript evidence — the manuscript Dominican Friars of Mosul 907 (olim Mosul, Chald. 97): we give a detailed description of the source and compare it with its later partial copies, Mingana syr. 18, Erbil, Chaldean Antonian Order of St. Hormizd (O. A. O. C.) syr. 92 (olim Notre-Dame des Semences 70), and with Mardin, Chaldean Cathedral 449 (olim Diyarbakır / Scher 25) — a manuscript containing a part of the penultimate treatise in Dominican Friars of Mosul 907.

   Also, systematizing our observations on the content and style of compilation of Mingana syr. 544 and Dominican Friars of Mosul 907, we prove that both are autographs of Simon the Persecuted, whose direct authorship for the treatises in Dominican Friars of Mosul 907 we refute and assert that they were created by an author named «mar Isaac» and may belong to the «Fifth Collection» of Isaac the Syrian. In this regard, we specify the problematization of the question and establish a direct connection between Simon’s auto graphs and the manuscript containing the «Second Collection» of Isaac, Bishop of Nineveh, — Bodl. Lib. syr. e. 7 whose dating was also reliably clarified.
