Musa bin Muhammad Qazi Zadeh al-Rumi (d.1436), known simply as Qazi Zaheh, was an Ottoman astronomer and mathematician based in Samarkand. Qazi Zadeh was a celebrated scholar in his field and is best known for the Zij’i Sultani, his collaborative work with fellow astronomer and Govenor of Samarkand Ulugh Beg (d. 1449). Their treatise is considered the first truly comprehensive stellar catalogue containing over 900 stars and is still considered an important treatise in the field of cosmology today. During his career Qazi Zadeh also became the directory of the Samarkan educational observatory, built under the direction and patronage of Ulugh Beg, which became the centre for astronomical research and education in the region.

The present text is a commentary on Mahmoud ibn Muhammad ibn Umar al-Jaghmini’s influential astronomical text entitled Al-Mulakhas fi’Ilm al-Haya (Compendium of Cosmology) which was likely compiled in the early 13th century. Qazi Zadeh’s treatise both acts as a summary and commentary of Jaghmini’s text, dealing with the configuration of the celestial and territorial worlds combined (including the arrangement of Ptolemaic celestial orbs). These treatises are compiled in a simplified format to accommodate a wider scholarly community and thus explain cosmographic theories in basic elementary terms and target broad audiences. The approachable nature of this text meant it became particularly widespread, often copied alongside Jaghmini’s text, and was even used as a curriculum for schools in Ottoman regions. 

This particular manuscript was probably copied for personal use by a scholarly student. Though there are wide margins throughout (for annotation) the text itself is miniscule and copied in a very tight format, an economic solution for self funding copyist. The contemporary marginalia and ownership seals are in keeping with the Eastern regions of Timurid Persia, not far from Samarkand, and probably copied only a few decades after the author’s death.
