Little is known about Khafrī’s life; he may have been influential in the program of the Safavid Shāh Ismā`īl (d. 1524) to make Shī`ism the official Islamic sect of Iran. Khafrī wrote works in both the fields of religion and astronomy (producing innovative planetary theories). Khafrī presented new models for the motions of the Moon, the upper planets, and Mercury. His model for the lunar motion combined features of `Urḍī and Quṭb al-Dīn al-Shīrāzī.  Khafrī seems to have been unaware of Ibn al-Shāṭir’s  work. The fact that Khafrī adheres so closely to Ptolemy’s observations and reproduces one of the major predictive failings of Ptolemaic theory suggests that Khafrī was more of a theorist than an observational astronomer. His major work is his astronomical treatise al-Takmila fī sharḥ “al-Tadhkira”,  a commentary on Naṣīr al-Dīn al-Ṭūsī’s Tadhkira. Two other works of his yet to be studied are: Muntahā al-idrāk fī al-hay’a (written as a refutation or a commentary on the Shīrāzī’s Nihāyat al-idrāk, and Ḥall mā lā yanḥall. [G. Cooper]
