President of the Reception Committee
The Author Shri Ram Swaroop Sharma has given to the
world of scholars an excellent and valuable treatise on the famous
Astronomer Brahma-Gupta, son of Jiṣṇugupta, born in 589 A. D.
in Bhillamala or Srimala now in Southern Marwad close to the
northern frontier of modern Gujarat. The work is divided into
13 chapters and at the end of each, the learned author has given
reference to other works and treatises for further study as also
in support of his various conclusions. He has described Astro-
nomy in Ancient India in the light of the knowledge of the
subject available in different countries in his time.
After giving personal details of Brahma-gupta, the author
starts on a critical study of the works of that Astronomer-parti-
cularly his Brahma-sphuṭa-siddhānta and Khaṇḍana-Khādya.
The author has also discussed the Indian Luni-solar Astronomy,
the Greek and Hindu methods in spherical Astronomy and the
Epicyclic theory of ancient Indians. Discussing in detail the
contribution of Brahma Gupta in Arithmetic, Algebra, in Astro-
nomy and the Astronomical instruments that he used, the author
has brought out the various highlights of his work and achieve-
ments in comparison with those of his predecessors, successors and
contemporaries in other countries.
The author deserves to be congratulated for this scholarly
contribution on the subject of Ancient Indian mathematics and
Astronomy.
