Siddhantic texts are ancient Indian scriptures that focus on the principles of Siddhanta, which means "conclusion" or "doctrine." These texts primarily deal with the mathematical and astronomical theories developed in ancient India, providing insights into the understanding of celestial bodies and their movements. They are essential for studying the historical development of Indian astronomy and mathematics. The most notable Siddhantic texts include the Surya Siddhanta and the Aryabhatiya. These works not only present calculations and methods but also reflect the philosophical and cultural context of their time. They have significantly influenced later scholars and continue to be studied for their contributions to science and mathematics.
