Kandilli Observatory and Earthquake Research Institute Manuscripts.

Mathematics, medicine, and astronomy were core disciplines of Islamic science during the Ottoman Empire (1285-1923) and many works on these subjects have been written in Turkish, Arabic, and Persian. This manuscript collection specializes in astronomical, astrological, mathematical, and miscellaneous works. It’s, perhaps, the only collection in the world that houses manuscripts on related subject matters and contains a number of unique and rare manuscripts. These works on astronomy and astrology are crucial for scholars and experts in subjects relating to the Ottoman Empire and the Islamic world, as well as to Western scholars in this field.
