A computational study of the 10th-century Ganita-Cudamani manuscript has unveiled a series of sophisticated Sanskrit algorithms for calculating the orbital precession of Venus. The findings, published in the Sanskrit Science Review on April 07, 2026, demonstrate that medieval Indian astronomers utilized iterative numerical methods that achieve an accuracy within 0.02% of modern celestial mechanics. The manuscript details a system of non-linear adjustments for planetary perturbations previously thought to have emerged during the European Enlightenment.
The research team employed AI-assisted script analysis to reconstruct missing sections of the palm-leaf manuscript found in a private collection in Tiruchirappalli. These algorithms suggest that the scholars of the era were practicing a form of discrete-time series analysis to account for the gravitational influence of neighboring planets. This discovery significantly elevates the historical standing of medieval Indian mathematics, highlighting a tradition of high-precision computational astronomy independent of Western influence.
