Dr. Bhagvánlál's view that the Jethvás are Medhs ennobled by long overlordship is somewhat doubtfully shared by Colonel Watson [487] and is not inconsistent with Tod's opinions. [488] Still though the Hindu ruler-worship, which, as in the case of the Marátha Siváji, explains the raising to the twice-born of leaders of successful early and foreign tribes makes it possible that the Jethvás were originally Mers, it seems on the whole probable that the Jethvás' claim to an origin distinct from the Mers is well founded. The evidence recorded by Colonel Tod and the name Jethva led the late Dr. John Wilson to trace the Jethvás to the Játs or Jits. [489] According to the bards the name of the Káthiáváda tribe Jethva is derived from Jetha No. 85 or No. 95 of the Porbandar list, who was probably so called because he was born under the Jyeshtha constellation. [490] The common practice of explaining a tribal name by inventing some name-giving chief deprives this derivation of most of its probability. [491] In the present case it may further be noticed that the name Jethi is borne by two of the chiefs earlier than the Jetha referred to. [492] In the absence of any satisfactory explanation the name Jethva suggests an origin in Yetha the shortened Chinese form of Ye-ta-i-li-to or Ephthalite the name of the ruling class of the White Húnas. [493] It is true that so good an authority as Specht [494] holds that the shortened form Yetha is peculiar to the Chinese and was never in use. But the form Tetal or Haital, adopted by Armenian Musalmán and Byzantine historians, [495] makes probable an Indian Yethál or Jethál if not a Yetha or Jetha. Nor does there seem any reason why Yetha the Chinese form of the word should not be more likely to be adopted in India than the western and otherwise less correct form Tetal or Haithal. In any case the irregular change from a correct Yethál to an incorrect Yetha cannot be considered of much importance, if, as seems likely, the change was made in order to give the word an Indian meaning. [496] The v in Jethva would come to be added when the origin from a chief named Jetha was accepted.
