Abstract
This study seeks to provide a historical perspective on optical problems by analyzing issues related to optics addressed by ʿAlī Qūshjī in his works Sharḥ al-Tajrīd and Taʿlīqāt ʿalā Mabāḥith al-Aghāliṭ al-Ḥissiya min Sharḥ al-Mawāqif and examining his use of different optical terms such as "ad-ḍawʾ (الضوء)", "an-nūr (النور)", and “ash-shuʿāʿ (الشعاع)”. In his work Sharḥ al-Tajrīd, ʿAlī Qūshjī offers a detailed exploration of the faculty of sight, drawing insights from mathematicians and natural philosophers on the nature of visual perception. He examines the formation of images in mirrors, delves into the concept of ḍawʾ (light), and discusses its significance in visual and color perception, as well as the limitations of conceiving ḍawʾ as an object. He concludes by addressing the challenges associated with seeing in the dark. In his treatise Taʿlīqāt ʿalā Mabāḥith ‘al-Agalit al-Ḥissiya min Sharḥ al-Mawāqif, ʿAlī Qūshjī further investigates topics such as the relative motion of an observer on a ship, methods for determining the size of objects reflected in mirrors using similar triangles, and the occurrence of different colors. Throughout his writings, he intricately weaves optical problems with broader issues in natural philosophy, discussing theories of motion and the physiology of the eye while bolstering his arguments with geometric representations. Additionally, he utilizes various terms for light when addressing light phenomena in both his Sharḥ al-Tajrīd and Taʿlīqāt.
