Jagannatha Samrat

Pandita Jagannatha Samrat (1652–1744) was an Indian astronomer and mathematician in the court of Jai Singh II of Amber. He learned Arabic and Persian in order to study Islamic astronomy. His works include Rekhaganita, a translation of Euclid's Elements made from Nasir al-Din al-Tusi's Arabic recension of same; Siddhantasarakaustubha, a translation of the Almagest from Arabic; and two works on astronomical instruments such as the astrolabe, Siddhanta-samrat and Yantraprakara, which also record astronomical observations made by Jagannatha.
