That Safavid Iran was scene to a boom in the occult sciences (ʿulum-i gharība) is now beginning to be acknowledged by specialists; what has yet to be appreciated is the extent to which that boom represented a smooth and conscious continuation of Mamluk, Aqquyunlu, Ottoman and especially Timurid Sunni precedent. In particular, lettrism (ʿilm-i ḥurūf), developed by the Pythagoreanizing, imamophile New Brethren of Purity as universal imperial science, was embraced by leading Safavid thinkers and doers as a primary Sunni means of Shiʿizing Iran. This occult continuity is epitomized by the oeuvre of Maḥmūd Dihdār Shīrāzī “ʿIyānī” (fl. 1576), the most prolific Persian author on lettrism of the sixteenth century and teacher to Shaykh Bahāʾī (d. 1621) himself. His Unveiling Secrets (Kashf al-asrār)—a passionate prosimetric paean to Imam ʿAlī as cosmic principle in strictly Akbarian-Būnian terms, like Rajab al-Bursī’s (d. after 1410) work before it—is contextualized and translated here as a case in point.
