In Vedic India, the science of geometry developed around the Yajña and for the construction of its Vedis. In no other country, geometry was developed with this objective and therefore, it is said that the geometry developed in this country was indigenous not borrowed from neighbouring countries and was meant for a specific purpose. The Boudhāyana Śulvasūtra is the oldest and biggest of all the Śulvasūtras. So Boudhāyana is the First Great Geometrician.
