Qutb al-Din al-Shirazi (1236–1311) was a 13th century Persian scientist from Shiraz, Iran. He and his master Nasir al-Din Tusi wrote critiques of the Almagest of Ptolemy. He also continued the optical studies of Alhazen. It was Qutb al Din who first gave a correct explanation for the formation of the rainbow. He produced two prominent works on astronomy - The Limit of Accomplishment concerning Knowledge of the Heavens (Nihayat al-idrak fi dirayat al-aflak) completed in 1281, and The Royal Present (Al-Tuhfat al-Shahiya) completed in 1284. Both presented his models for planetary motion, improving on Ptolemy's principles. Besides astronomy he wrote extensively on medicine, mathematics and "traditional" Islamic sciences. Qutb al-Din was also a Sufi from a family of Sufis in Shiraz. He is famous for the commentary on Hikmat al-ishraq of Suhrawardi, the most influential work of Islamic Illuminist philosophy. Qutb al-Din Shirazi's most famous work is the Pearly Crown (Durrat al-taj li-ghurratt al-Dubaj), written in Persian around 1306 (705 AH).
