Dear all:Very briefly, this book offers a critical edition and an English translation (accompanied by critical notes and technical analyses) of the chapter on spheres (golādhyāya) from Nityānanda’s Sarvasiddhāntarāja, a Sanskrit astronomical text written in seventeenth-century Mughal India. The introductory and technical discussions in this book provide a sense of how Sanskrit astronomical thought thrived in early modern Mughal India; in particular, how terrestrial and celestial phenomena were understood by Sanskrit astronomers using spherical geometry. I hope that this book will be of interest to historians and philosophers of science, in particular those interested in the history of non-Western astral sciences, as well as to historians of astronomy interested in the ways in which Sanskrit and Indo-Persian astronomy interacted in Mughal India.
