CHAPTER XLIX.                           7

The era of Valabha is called so from Valabha.the ruler Era of
of the town Valabhi, nearly 30 yojanas south of Anhil-
vara. The epoch of this era falls 241 years later than Page 206.
the epoch of the Saka era. People use it in this way.
They first put down the year of the Sakakala, and
then subtract from it the cube of 6 and the square of
5 (216 + 25 = 241). The remainder is the year of the
Valabha era. The history of Valabha is given in its
proper place (cf. chap. xvii.).

were wicked powerful people, and that when they
ceased to exist this date was used as the epoch of an
era. It seems that Valabha was the last of them, be¬

The era of the astronomers hegina 587 years later than Era of the
