Note 4 — Chapter VIII · THE VALABHIS (a.d. 509–766.)
Reading edition
Jayasiṃhavarmman, a.d. 666–693.The regular establishment of Chálukya power in South Gujarát seems to have been the work of Dháráśraya Jayasiṃhavarmman son of Pulakeśi II. and younger brother of Vikramáditya Satyáśraya (a.d. 670–680). A grant of Jayasiṃhavarmman’s son Śíláditya found in Navsárí describes Jayasiṃhavarmman as receiving the kingdom from his brother Vikramáditya. As Jayasiṃhavarmman is called Paramabhaṭṭáraka Great Lord, he probably was practically independent. He had five sons and enjoyed a long life, ruling apparently from Navsárí. Of the five Gujarát Chálukya copperplates noted below, three are in an era marked Saṃ. which is clearly different from the Śaka era (a.d. 78) used in the grants of the main Chálukyas. From the nature of the case the new era of the Gujarát Chálukyas may be accepted as of Gujarát origin. Grants remain of Jayasiṃhavarmman’s sons dated Ś. 421, 443, and 490.4 This checked by Vikramáditya’s known date (a.d. 670–680) gives an initial between a.d. 249 and 259. Of the two Gujarát eras, the Gupta-Valabhi (a.d. 319) and the Traikúṭaka (a.d. 248–9), the Gupta-Valabhi is clearly unsuitable. On the other hand the result is so closely in accord with a.d. 248–9, the Traikúṭaka epoch, as to place the correctness of the identification almost beyond question.
