The Gupta Golden Age
Under the Gupta emperors, northern India entered a golden age whose scholars handed the world gifts it still uses daily: the numeral system with zero and place value we now miscall 'Arabic,' strikingly accurate estimates of pi and the length of the year, and the theory that the Earth turns on its axis. Sanskrit literature, temple art, and mathematics flourished under a relatively light imperial hand. The Gupta achievement is easy to overlook precisely because it succeeded so completely — the zero on this page is their monument.
A durable new order — a state, an institution, a system of rule — is deliberately built and consolidated, outlasting the people who founded it.
