Content

Commentary by Luṭf Allāh al-Muhandis ibn al-Ustādh Aḥmad al-Mi‘mār al-Lahūrī (لطف الله المهندس بن الأستاذ أحمد المعمار اللهوري, fl. second half of 17th century) on the Summa of Arithmetic (خلاصة الحساب) by Bahā’ al-Dīn Muḥammad ibn Ḥusayn al-‘Āmilī (بهاء الدين محمد بن حسين العاملي; d. 1621). The commentator's father, Ustādh Aḥmad al-Lahūrī (أستاذ أحمد اللهوري), was chief architect of the Tāj Maḥal (built 1632-53).

The margins contain many annotations written and signed by the commentator's son Imām al-Dīn ibn Luṭf Allāh (see especially the note in the tail margin to gutter margin of f. 8r where the annotator signs his name 'Imām al-Dīn, son of Luṭf Allāh the commentator of this book' [إمام الدين بن لطف الله الشارح لهذا الكتاب]). Other marginal annotations are signed Khalkhālī (خلخالي, see e.g. annotations in margins of f. 8v) and ‘Abd al-Karīm (عبد الكريم, see e.g. note in middle of tail margin of f. 17r).

The text contains numerous diagrams.

Begins (f. 4v, lines 2-5):

الحمد لله الواحد الفرد الصمد الذي لا يحاط

جمع نعمه وتضاعف قسمه بالعدد والصلوة على

من يرجى حير كسور جرائمنا بتقابل شفاعته يوم

الحساب ...

Ends (f. 69r, lines 9-11):

فإن كثيرًا من مطالبها حري من الصيانة

والكتمان حقيق بالأستار عن أكثر أهل هذه

الزمان فاحفظ وصيتي إليك والله حفيظ عليك تم
