Ghulām Ḥusayn Junpūrī's Principle of Optics

The present article discusses and criticizes the chapter two of Bahādurkkhānī’s Jāmī‘ on optics. The basic question is the extent to which this book is influenced by old book of optics. The main hypothesis is that despite all scientific advances in new optics, Bahādurkkhānī’s Jāmī‘ still relies on optics of ancient Greece and his Islamic era and does not step beyond Euclidean mathematics. According to his references to geometric relationships and the last astronomical discoveries we can say that Bahādurkkhānī probably was aware of the latest advances in new geometric optics. As a result, optics and mathematics had a strong geometric aspect in the India of 19th century without deep philosophical aspects.
