Kātyāyana
300 BCE–200 BCE
Kātyāyana was the author of the Kātyāyana Śulba Sūtra, one of the principal texts of Vedic geometry used for constructing sacrificial altars. His sūtra gives a general form of the Pythagorean relation and an accurate approximation of the square root of two, and is usually counted as the last of the major Śulba-sūtra geometers. He is the Śulba-sūtra mathematician, a tradition distinct from the later grammarian Kātyāyana. Only a floruit is known (roughly c. 300–200 BCE); the birth and death years given here are approximate bracketing values, not documented dates.
