224 Pandit Bapu Deva S'astri— A brief account of BbdsJcara. [No. 3, 
and it appears to me that he was an inhabitant of Vijapura, the 
ancient metropolis of the Karnatik. Some say that he was a Maratha 
Brahman follower of the Tajnrveda; but his method of annotating, 
which is still current in the Karnatik in annotating poetical works, 
shews that he was a Kanara Brahman of Yxjapura. His father, named 
Mahesvara, was a very great Pandit and Astronomer, and a virtuous 
man. He had acquired the title of Ach&rya (Doctor) in the assembly 
of the Pandits. 
Bhaskara studied all the sciences acquired by him with his father. 
It cannot be ascertained whether he or his father was patronized by 
any Raja, or whether he was a rich or poor man. But it is certainly 
time that he was expert in science, a very great poet, and an excellent 
Astronomer. 
In his time, Lalla’s work on astronomy, called S'ishija-dhivriddhida-. 
Tantra, more usually styled the DMvriddliida simply, was much used, as 
the Siddhdnta-S'iromani is at present. Bhaskara first made a commentai’y 
on Lalla’s work, and then wrote his own work on astronomy, called 
Siddhdnta-S'iromani, in two parts, Ganitddhydya and Golddhydya, compos- 
ing before it two introductory works : the first on Arithmetic, called 
Pdti, or Lilavati, and the second on Algebra* He compiled his excellent 
work Siddhdnta-S'iromani in the 36th year of his age, or 1 1 50, A. D. 
Its first part, Ganitadhyaya, is divided into 12 chapters, viz. : — 
Chapter I. Called the Madhyagati, which treats of the rules for 
finding the mean places of the planets, contains 7 sections. 
Section 1. Kinds of time. 
Section 2. Revolutions of the planets, &o. 
Section 3. Rules for finding the ahargana (or enumeration of 
mean terrestrial days elapsed from the commencement of the Kalpa) 
and thence the mean places of the planets, &o. 
Section 4. The dimensions of the Brahmanda (universe), and of 
the orbits of the planets, and thence the rules for finding the mean 
places of the planets. 
Section 5. This section, called Pratyabda-Suddhi (the remainders 
of additive months at the beginning of each year), treats of rules for 
finding the remainders of additive mouths, subtx’active days, &c., at 
the beginning of each year, the small ahargana (or enumeration of 
the days elapsed from the beginning of the current year) and thence 
the mean places of the planets. 
Section 6. Determination of additive months and others. 
Section 7. The Desdntara correction, &c., and conclusion of the 
first chapter.
