- Bhaskara I, the author of the Maha-Bhaskariya, was a different person from his namesake of the twelfth century A. D., the author of the Siddhanta-Siromani and Lilavati, etc. He lived in the seventh century of the Christian era and was a contemporary of Brahmagupta (628 A.D). He wrote three works on astronomy which were composed in the following order: (1) the Maha-Bhaskariya, (2) a commentary on the Aryabhatiya, and (3) the Laghu-Bhaskariya. His commentary on the Aryabhatiya was written in 629 A. D., i.e., one year after the completion of the Brahma-sphuta-siddhanta of Brahmagupta.
Bhaskara I was a follower of Aryabhata I, the author of the Aryabha fiya. His works provide us with a detailed exposition of the astronomical methods taught by Aryabhata I and throw light on the development of astronomy during the sixth and early seventh century A. D. in India. For details regarding the life and works of Bhaskara I, the reader is referred to Part I of the present work.
