s. XVII | Paper (W. 2137 Briquet (like Ra 1807)), 312 + 9 ff., 344 × 210 mm | Provenance: Schleusingen, Hennebergische Gymnasialbibliothek (HGB). Schleusingen was the place where Paul de Lagarde (1827–1891) spent a three-year research leave as a teacher before being appointed professor in Göttingen in March 1869; Lagarde is known to have worked on the cataloguing of the library. In 1958, the Gymnasialbibliothek was transferred into the Heimatmuseum Schleusingen at Schloß Bertholdsburg. A letter by David Hoeschel explains the provenance of this manuscript (the letter is kept under the siglum MB Q 1 (9) in the historical library, personal note by the librarian, Janis Witowski, 2023-02-08). | Owner: Wolfgang Seber (1573–1634)  On Seber, who was director of the Schleusingen Gymnasium between 1600–1610, see here.

Commentary on Psalms by Theodoret of Cyrrhus. | Parchment binding with re-used Missale text (like Ra 1807). The Manuscript consists of two parts (I–II) which are bound together. Both parts seem to have been copied from Augsburg manuscripts which are now kept in Munich. According to Wendel, part 1 was copied from Cod. Monac. gr. 478 (Ra 9038).
