_ Here also we get the same method of finding out the 
libration and the same annual measure of it, viz., 54 seconds. 
All these three astronomical treatises hail from a very 
remote antiquity and the determination of the respective 
priority of the one to the other is rather difficult although not 
an altogether hopeless task. The author of ‘Sambhu-Hora- 
Prakasa’ expressly says :— 
“aig: fag wa: atest at F cat wart ATA |

(Ch. 1, verses 6 and 7). 
The dialogue between Siryya and Aruna assigns the oldest 
position to Brahma-Siddhanta, Vasistha-Siddhanta coming 
next, and Siryya-Siddhanta being put third. So that both of 
these traditions place Sirya-Siddhanta as the third in chrono- 
ogy. Not only tradition but internal evidence as well would 
must have improved upon its predecessor the Soma. Hence 
the dispute now remains between ‘Soma’ and ‘ Brahma.’ In 
my opinion, the tradition recorded in Sambhu-Hora-Prakasa 
seems to be nearest truth. I give here only a few salient 
verses 1 to 24 and again 67 to 80), while Brahma is extremely 
matter-of-fact in tone and narration. (4) If Siryya-Siddhanta 
is to improve upon or follow any of his predecessors. it 18 most
