This volume presents comprehensive investigations into various facets of observational astronomy during the medieval Islamic period, spanning from the ninth to the seventeenth centuries. The chapters compiled here, originally published between 2012 and 2018, have undergone significant revisions to enhance their accuracy and explore a broad spectrum of topics organized into five main sections.

Reflections on Observational Astronomy in the Medieval Islamic Period begins with solar astronomy, providing a detailed evaluation of Islamic astronomers’ determinations of fundamental solar parameters. In the realm of lunar astronomy, it examines the gradual endorsement and rationalization of annular solar eclipses, along with an exclusive historical account of predicting and observing such an event in 1283 CE. The section on planetary astronomy scrutinizes empirical discoveries that distinguish between the precession of equinoxes and the motion of apogees, as well as significant enhancements to Ptolemy’s parameters for planetary latitudes. Stellar astronomy is explored through a non-Ptolemaic star table that encompasses observations from ninth-century Baghdad to thirteenth-century Marāgha. The final section examines observational instruments, focusing on those constructed during the second period of activities at the Marāgha observatory. A critical analysis of astronomical observations conducted at the Marāgha and Istanbul observatories is a key focus of this work.

This book will be invaluable to those interested in the historical progression of exact sciences; the scope, distinctive aspects, and caliber of experimental activities in medieval times; and the interplay between theory and observation throughout history. It is intended for historians, scientists (including astronomers and physicists), and particularly, historians of astronomy.

S. Mohammad Mozaffari is an Iranian historian of medieval astronomy currently serving at the Research Institute for Astronomy and Astrophysics of Marāgha (RIAAM), University of Maragheh, in Iran. He is also a research associate in the project of the Ptolemaeus Arabus et Latinus (Bavarian Academy of Sciences and Humanities, Munich). His primary research focus lies in the growth and development of observational astronomy, particularly its interplay with theoretical astronomy, during the medieval Islamic period. He is an active member of the International Astronomical Union and holds editorial roles as an advisory editor for the Journal for the History of Astronomy, an associate editor for SCIAMVS (Sources and Commentaries in the Exact Sciences), and an associate editor for the Journal of Astronomical History and Heritage.
