Suryadeva (1191 – at least 1248 CE) was a Sanskrit-language writer on astrology and astronomy (jyotisha)) from the Chola kingdom of southern India.
Suryadeva was a Brahmana of the Nidhruva gotra, associated with the Bodhayana Sutra, claiming descent (pravaras) from the sages Kashyapa, Avatsara, and Naidhruva.
[1] According to his commentary on Laghumanasa, Suryadeva was born in 1191 CE (Monday, 3rd day of the dark half of the Magha month of the Shaka year 1113).
[1] Suryadeva appears to have read a large number of previous works, as he refers to earlier scholars such as Lagadhacharya, Vrddha Garga, Parashara, Aryabhata I, Haradatta (Haridatta), Latadeva, Varahamihira, Bhaskara I (whom he calls "Bhaskaracharya"), Brahmagupta, Lalla, Prthusvamin (Prthudaka Svami), Prashastidhara (Whom he calls "Prasastadhara"), Bhattotpala, and Shripati.
[5] Later writer Yallaya (c. 1480), in his commentary on the Surya Siddhanta, praises Suryadeva as an "all-knowing astronomer".
