________________
THE POST-MAITRAKA PERIOD
85
Accordingly, it appears that the samvatsaras given in the dates mentioned above would fit in if the S'aka years be taken to be current rather than expired. The samvatsara mentioned in relation to S'aka 836 would then tally according to the first Arya Siddhānta and the Brahmu Siddhānta, but not according to the original Sürya Siddhānta and the Brhatsamhitā rule. Hence it may be inferred that the calendar followed by these records was probably based on either the First Arya Siddhānta or the Brahma Siddhānta.
As the former is used in Kerala and Madras States, 34 while the latter was followed till recently in Gujarat and parts of Rajasthan35, it follows that the Brahma Şiddhānta prevailed in Gujarat during this period,
(iv) The Vikrama Era
The known epigraphic records of the post-Maitraka period hardly give dates in the Vikrama Era. Exceptionally the Una plates of the Cālukya King Avanivarman II, a feudatory of the Pratihāra sovereign Mahendrapāla, are dated in the year 956 which though unspecified, obviously seems to belong to the Vikrama Era.36
Among literary works of this period, Byhatkathākoša by Harişena is specficially dated in the year 989 of the Vikrama Era along with the year 853 of the Saka Era.37 As the samvatsara Khara tallies with the Saka year, 34-35.
