Athir al-Din al-Abhari (d. ca. 656/1258) was an outstanding Iranian polymath who wrote numerous treatises including Bayan al-Asrar, Talkhis al-Haqa’iq, Risalat al-Matali’, and Zubdat al-Haqa’iq. Each treatise contains three subjects: logic, physics, and metaphysics. They were copied by Katebi al-Qazwini. Al-Abhari himself has written ijaza at the beginning of them. The four handwritings are reserved in MS Fazil Ahmed Pasha 1618, in the Library of Kuprili, at Istanbul. In this study I have edited the Logic of Zubdat al-Haqa’iq. Abhari’s logic in this work is purely Avicennan.
