ARYA-BHATTA (b. 476), Indian astronomer and mathe matician, was born at Patalipatua on the upper Ganges. He was the author of the Aryabathiyam, written in verse couplets, which gives the rules of mathematics as known in his time. The greater part of this work is astronomy and spherical trigonometry, the remainder being 33 rules in arithmetic, algebra and plane trigo nometry, including quadratic equations, the sums of powers of the first n natural numbers, and a table of sines. The work was pub lished in Sanskrit at Leyden in 1874 (French trans. 1879).
