Aryabhata

Aryabhata was one of the foundational figures of classical Indian mathematical astronomy. His Aryabhatiya, composed around AD 499, set out computational methods for planetary positions, eclipses and calendrical astronomy. It also described the apparent daily motion of the sky in terms of the rotation of the Earth, an important insight in the history of astronomical thought.

Why Aryabhata matters in astronomy

His work links mathematical technique with observational astronomy and illustrates that major developments in astronomy were taking place far beyond medieval Europe. The World History Database records below place Aryabhata within the longer chronology of astronomical ideas.
