The Islamic astronomy including the Persian astronomy was thoroughly introduced into India from the 14th century AD or so. Firstly, the astrolabe was introduced at the time of F?r?z Sh?h Tughluk?, and a Sanskrit work entitled Yantra-r?ja (1370 AD) was composed by Mahendra S?ri. At that time, some Sanskrit astronomical (or astrological) works were also translated into Persian. The astrolabe became quite popular in India, and Padman?bha wrote the second Sanskrit work on the astrolabe in 1423 AD. During the Delhi Sultanate period and the Mughal Empire period, Islamic astronomy and Hindu Classical astronomy influenced each other. I would like to discuss the introduction of the astrolabe into India and the development of astronomy in India in this period.
