Quṭb al-Dīn al-Shīrāzī's Appendix to Book I of his Persian Translation of Euclid: Text, Context, Influence

The first part of the paper describes the Persian translation of Naṣīr al-Dīn al-Ṭūsī’s Taḥrīr Kitāb Uqlīdis by Quṭb al-Dīn al-Shīrāzī، with a primary focus on his appendix to book i. Part of a larger encyclopedic collection، al-Shīrāzī’s translation continued to be read for centuries. As evidence of the work’s influence، al-Shīrāzī’s appendix to book i was included in a nineteenth century printed edition of Muḥammad Barakat’s commentary on book i of al-Ṭūsī’s treatise. I discuss this later use of al-Shīrāzī’s appendix in the second part of the paper.
