This 18th-century manuscript in Garshuni (Arabic written in Syriac letters) contains two works and part of another. The manuscript is without foliation, but before what would now be folio 11v, some folios are missing, so that the first work, part of a Christian polemical text, is cut short and a new work begins: Isagoge, or Introduction to Logic (Al-muqaddima fī ta’rīf al-manṭiq wa-ajzā’ihi). A Porphyrian tree diagram is on folio 29v and there are several other diagrams as well (for example, 53v, 56r–57v). According to the colophon on 93r, the manuscript was copied by a scribe named Stephen (Isṭifānūs), a monk of the Saint Antony Monastery, completed on the 11th of Nisan (April), 1737, in Rome. The work is a composition of the monk Yuwāṣaf (Joasaph, 1690–1737) of the village of Baskinta in Lebanon, attached to the Monastery of Saints Peter and Marcellinus in Rome. The manuscript is marked as the property of the monks of Lebanon, and concludes with a short Syriac–Garshuni glossary.
