The grant of Pulakesivallabha Janásraya dated Samvat 490, mentions Mangalarasaráya as the donor's elder brother and as the son of Jayasimhavarmman. And a Balsár grant whose donor is mentioned as Mangalarája son of Jayasimhavarmman, apparently the same as the Mangalarasaráya of the plate just mentioned, is dated Saka 653. [161] Placing the elder brother about ten years before the younger we get Samvat 480 as the date of Mangalarája, which, corresponding with Saka 653 or A.D. 730-31, gives A.D. 730 minus 480 that is A.D. 250-51 as the initial year of the era in which Pulakesi's grant is dated. In the Navsári plates, which record a gift by the Gurjjara king Jayabhata in Samvat 456, Dadda II. the donor of the Kaira grants which bear date 380 and 385, is mentioned in the genealogical part at the beginning as 'protecting the lord of Valabhi who had been defeated by the great lord the illustrious Harshadeva.' Now the great Harshadeva or Harsha Vardhana of Kanauj whose court was visited by the Chinese pilgrim Hiuen Tsiang between A.D. 629 and 645, reigned according to Reinaud from A.D. 607 to about A.D. 648. Taking A.D. 250 as the initial year of the era of the Kaira plates, Dadda II.'s dates 380 and 385, corresponding to A.D. 630 and 635, fall in the reign of Harshavardhana. These considerations seem to show that the initial date of the Traikútaka era was at or about A.D. 250 which at once suggests its identity with the Chedi or Kalachuri era. [162] The next question is, Who were these Traikútakas. The meaning of the title seems to be kings of Trikúta. Several references seem to point to the existence of a city named Trikúta on the western seaboard. In describing Raghu's triumphant progress the Rámáyana and the Raghuvamsa mention him as having established the city of Trikúta in Aparánta on the western seaboard. [163] Trikútakam or Trikútam, a Sanskrit name for sea salt seems a reminiscence of the time when Trikúta was the emporium from which Konkan salt was distributed over the Dakhan. The scanty information regarding the territory ruled by the Traikútakas is in agreement with the suggestion that Junnar in North Poona was the probable site of their capital and that in the three ranges that encircle Junnar we have the origin of the term Trikúta or Three-Peaked.
