INTRODUCTION occur in the annotative works of Suryadeva (b. 1191 A.D.), Yallaya (1480 A.D.), NUakantha (1500 A.D.), Raghunatha Rnja (1597 A.D.), Govinda Somayajt and Visnu 6arma, and in the Prayoga-racariS, an anonymous commentary on the MaKi- BHiskarlya. Quotations from the Laghu-BhZskarlya are found to occur not only in astronomical and astrological works but also in works on other subjects. For example, one quotation occurs in Karavinda Svaml's commentary on the Ap&stamba-sulba-butra. Some passages from the Laghu-BhZskariya have also been adopted verbatim or with slight verbal alterations in the Tantra-sahgraha of Nllakantha (1500 A. D.). A list of passages quoted or adopted in later works is given in Appendix 2 at the end of this book. 1 Another evidence of the popularity of the Laghu-Bhiskarlya is the occurrence of commentaries on this work, written in Sanskrit as well as in provincial vernaculars, such as Malayalam and Tamil. Amongst the notable commentators may be men- tioned the names of &ankaranarayana (869 A. D.), Udaya- divakara (1073 A.- D.) and Paramesvara (1408 A.D.). Authorship. The author of the Lagku-BhSskartya bears the name Bhaskara as is evident from the closing stanzas of his works, the MakS-Bfi&skarlya and the Laghu-BhSskartya. But he is a different person from his namesake of the twelfth century A. D., the celebrated author of the Siddhlinta~kiromani> IMHvaii t and Bijaganita, etc. He lived in the seventh century of the Christian era and was a contemporary of Brahmagupta (628 A. D.). To distinguish between the two Bhaskaras, I have called the author of the Mah&'bhftskariya and the Laghu-Bhaskarlya by the name Bhaskara I and the author of the Siddhinta-siromani by the name Bhaskara II. 1 Sec pp. 115-119.
