Qutb al-Din Mahmud Shirazi's Sharh Qanun ibn Sina

This commentary, known as the Tuhfah al-Sa'diyyah, is one of the most famous commentaries on Ibn Sina's medical encyclopaedia, the Qanun fi'l-Tibb. It was dedicated by the author to Sa'd al-Din Savaji, a vizier of the Ilkhan Öljeytü (r 1304–1317). This copy, which is written in two different hands, is undated, but the earlier hand, like the format, is typically Ilkhanid. The copying may have been continued in later 14th-century Egypt or Syria, since folio 1a bears a characteristically Mamluk dedication page, and a librarian's note dated 772 AH (1373–4 AD).
