1.18 Dr. Hoernle — Gauhatl Copper-plate Grant of Indrapala. [No. 2, 
accordingly, that of Brahmapala about 1000 A.D. There is thus an 
interval of about 360 years between Hiuen Tsiang and Brahmapala; 
and it may have been somewhat longer. As will be shown presently, 
between Vajradatta and Brahmapala there were twenty-one kings. At 
the rate of 20 years for a reign, these kings would take up 420 years, 
or at the rate of 15 years, 315 years. On the supposition, therefore, 
that the “ Kaumra ” line took its name from Kumara Bhaskara of 
Hiuen Tsiang’s time, it seems quite possible to accommodate Vajradatta, 
who is said to have been of the Kaumra line, together with his twenty- 
one successors in the interval between Hiuen Tsiang and Brahmapala. 
But there is another interesting point in our genealogy, viz., a 
curious discrepancy. 
The usual Asam tradition is that Bhagadatta and Vajradatta were 
brothers, both being the sons of Naraka, Bhagadatta apparently being 
the elder of the two, and he it was that succeeded his father on the 
throne of Pragjyotisa. See Mr. Gait’s paper on the Koch Kings of 
Kdmarupa , in this Journal , Vol. LXII, p. 271. This account is borne 
out by the Tejpur copper-plate grant of Vanamala published in this 
Journal , Vol. IX, p. 766. According to it the genealogy runs thus : 
1, Hari, the God. 
2, Naraka, founder of Pragjyotisa, son of No. 1. 
3, Bhagadatta and Vajradatta, sons of No. 2. 
4, Undefined number of kings of the line of Bhagadatta. 
5, Sahistambha, of a new line of an undefined number of 
kings, ending with prl-Harisa. 
6, Pralambha, said to be again of the line of Bhagadatta. 
7, Harjara, son of No. 6. 
8, Vanamala, son of No. 7. 
On the other hand, the Gauhatl grant makes Vajradatta to be 
the son of Bhagadatta; and in this it is in agreement with the Now- 
gong grant of Balavarman. 8 The genealogy, as given in the latter, 
runs as follows :— 
1, Hari (called Upendra). 
2, Naraka, founder of Pragjyotisa, son of No. 1, 
3, Bhagadatta, son of No. 2. 
4, Vajradatta, son of No. 3. 
5, Undefined number of kings of his line. 
6, Salastambha, of a new line. 
7, Palaka, Vijaya and others, descendants of No. 6, occupying 
an undefined interval. 
8 This is another Asam coppcr-plate grant, brought to light by Mr. Gait, 
which will be published by me in a subsequent paper.
