Mathematical Treasure: 16th-Century Indian Astronomy

Frank J. Swetz (Pennsylvania State University)

Gaṇeśa Daivajne (ca. 1507–1554) was an Indian astronomer. His Grahalāghava is a treatise on Hindu astronomy and mathematics believed to be composed when he was quite young (ca. 1520). Here are excerpts from a [paper] manuscript of this work from the period 1700–1850. Note that numerical computations are separated from the script by enclosed boxes.
