be the third astronomer of the name. That this Varaha 
flourished in the first half of the sixteenth century would be 
manifest from his 21st (23rd of other editions) verse of the 
Ist chapter, where he enjoins upon deducting 1450 from the 
Saka era. ules 
“qarataTa aarmafaayfearg

He was, in all probability, a Bengali living in the Radha 
country (roughly answering our present Burdwan division) as 
can be well inferred from his following verses on Desantara- 
nayana. 2 
“Way (ye) strafed ce SMA HIT

According to this author the average annual libration is 
54 seconds. His formula for finding out the libration of a 
particular year is this :— 
“qrawafaaets fe aat eafretq |

(Tri-prasnadhikara Chapter, verse 11). 
ie. from the Saka vear under consideration 421 is to be 
deducted. Then the residue is to be put down in two places. 
One of them is to be divided by 10, and the quotient is to be 
deducted from the other number. The result obtained would 
be the amount of precession (or recession) minutes for the year 
ll. Siddhanta-ruhasya : —(Raghavananda) (1513 Saka or 
1591 A.D.). 
According to this work also the annual rate is 54 seconds. 
The verse giving the formula for finding out the precession (or 
recession) of a particular vear is nearly the same as in 
Jatakarnava.
