Antiquity of Geometry

The Science May Have Existed In India For Long Ages

Did we learn our rule of three and our Euclid from India? Researches have brought to light astronomical tables in India which must have been constructed by the principles of geometry. Some are of the opinion that they have been framed from observations made not less than 3,000 years before the Christian era, and if this opinion be well founded the science of geometry must have been cultivated in India to a considerable extent long before the period assigned to its origin in the west, so that many of the elementary propositions may have been brought from India to Greece.

The Indians have a treatise called the "Surya Sidhanta," which professes to be a revelation from heaven communicated to Meya, a man of great sanctity, about 4,000,000 years ago. This book contains a rational system of trigonometry which differs entirely from the first known in Greece and Arabia. In fact it is founded on a geometrical theorem which was not known to the geometricians of Europe before the time of Victa, about 200 years ago. And it employs methods of demonstration unknown to the Greeks, who used others. The former have been attributed to the Arabs, but it is possible they have received this improvement in trigonometry as well as the numerical characters from India. — Chicago Tribune.
