INTRODUCTION xxi In addition to the two works mentioned above, Bhaskara I wrote one more work on astronomy, viz. a commentary on the Aryabhatiya. In Part I, I have shown that the three works of Bhaskara I were written in the following chronological order: ( 1 ) The MaM-BUskarxya (2) Commentary on the Aryabhatiya (3) The Laghu-Bh'Sskartya At two places in the commentary on the Iryabhaflya, Bhas- kara I has mentioned the time elapsed since the beginning of the current Kalpa (Aeon). Thus in his commentary on the eighth gttikZ-sutra (1, i. 9), he writes: "Since the beginning of the (current) Kalpa (Aeon) the number of years elapsed is this: zero, three, seven, three, twelve, six, eight, nine, one (proceeding from right to left) years. The same (years) in figures are 19861 23730." 1 Under the same gltikH-sutra, he again writes: "The time elapsed, in terms of years, since the com- mencement of the (current) Kalpa is zero, three, seven, three, twelve, six, eight, nine, one (years). The same (years written in figures) are 1986123730." 2 Now the number of years elapsed since the beginning of the current Kalpa at the commencement of Kaliyuga 3 = 6 manus +27% yugas ~6 x 72 yugash 21 yugas = (432 + 11 1/4) x 4320000 years = (1866240000 + 119880000) years = 1986120000 years. 1 ^FTT^5^T^^T Srs^TfofefrntrT: «|i4fc<MI*<WNlTON*: I 1986123730. a w 1986123730. 1 See a. i. 5.
