The Aryabhatiya puts numerical tables to work in astronomy
Aryabhata's Sanskrit verses organize mathematical astronomy, including sine tables, eclipse calculations and an account of Earth's rotation.
The story
Internal chronological information dates the work to 499. Compressed verses supported memorization but required commentary to unfold their procedures. Aryabhata explained daily celestial motion through Earth's rotation; this was not a modern, fully heliocentric system. His text and its interpreters shaped a continuing tradition of mathematical astronomy.
Connections and context
Arabic-speaking scholars adopted and transformed Indian tables and procedures. Transmission changed terminology and questions rather than simply copying a finished system.
