Lalla comes after Brahmagupta. There are different views about his date. Dr. Kern and Janardan Balaji Modak put him in S.E. 420 (498 A.C.) and Sudhakar Dvivedi holds that he lived in S.E. 421 (499 A.C.), while Sh. B. Dixit dates him round about S.E. 560 (638 A.C,)66. His famous work on Jyotişa is Dhīv;ddhidatantra. He wrote a muhūrtagrantha named Ratnakośa.

Samhitā and Jātaka and made commentaries on Khandakhādya
and Brhajjātaka (BJ, p. 318). 70. Op. cit., p. 318 71. Colebooke determined the dates of some astronomers according
