The image above comes near the end of the long colophon (ff. 116r-118r) of CCM 89 (olim Diyarbakır 19; Macomber 12.35), an Epistle Lectionary in Syriac dated August 1539 (1850 AG; 946 AH), copied in “Gāzartā d-Bēt Zabday, on the Tigris” by a scribe named Darwiš b. Ḥannā b. ʕisā of the aforementioned village. Here is an ET of the text given above, which in the colophon follows mention of a dispute about the times of certain feasts:
Anyone reading the Chronicon made by Rabban Šemʕon Šanqlāwāyā, the teacher of Rabban Yoḥannān bar Zoʕbi, knows these things clearly. Pray for me with the love of our Lord.
Šemʕon Šanqlāwāyā is not among the most well-known Syriac writers, but we do at least know his name from elsewhere (see L. Van Rompay in GEDSH, 374), and the work mentioned here, the Chronicon, survives in more than one manuscript, but only parts of it have been published: in Müller’s 1889 dissertation, together with German translations. The note from the colophon does not tell us anything new either about the author or his work in and of themselves, but it does tell us that the Chronicon was known, respected, and presumably accessible in or around Gāzartā in the sixteenth century, some three centuries after Šemʕon died.
