The Hindu-Arabic Numerals c5.39

c5.39

This *Sindhind* is the book, says Mas'ūdī,² which gives all that the Hindus know of the spheres, the stars, arithmetic,³ and the other branches of science. He mentions also Al-Khowārazmī and Ḥabash⁴ as translators of the tables of the *Sindhind*. Al-Bīrūnī⁵ refers to two other translations from a work furnished by a Hindu who came to Bagdad as a member of the political mission which Sindh sent to the caliph Al-Manṣūr, in the year of the Hejira 154 (A.D. 771).
