The Corrected Treatise of Brahma

Chapter on the Mean Motions of the Planets

original: "Brāhmasphuṭasiddhānta" — This title literally means 'The Corrected Astronomical Siddhānta of Brahma.' Composed in 628 CE, it is one of the most influential works in the history of mathematics and astronomy.

original: "Madhyamādhikāra" — This is the first chapter of the treatise. It focuses on calculating the 'mean' or average positions of celestial bodies, assuming they move in perfect circles at constant speeds before applying corrections for their actual elliptical paths.
