The Uttara-Kurus seem already in the time of the Aitareya Brāhmaṇa to have won a somewhat mythical reputation, for when Atyarāti Jānaṃtapi, who was not a king, proposed to conquer them as well as the rest of the world, he was dissuaded by his priest Vasishṭha Sātyahavya, and for his rashness was defeated by Amitratapāna Çushmiṇa, the king of the Çibis, a tribe no doubt identical with the Çivas of the Rigveda and belonging to the north-west. The Uttara-Madras must have lived near them in Kashmīr; and the Madras of whom we hear in the Bṛihadāraṇyaka Upanishad were, in the Buddhist epoch, settled between the Chenāb and the Rāvi. In the Middle Country with the Kuru-Pañchālas were the Vaças and Uçīnaras who seem to have been of no importance. With them in the Kaushītaki Upanishad are coupled the Matsyas, and we hear of one great Matsya king, Dhvasan Dvaitavana, who performed the horse-sacrifice and who probably ruled in or about Jaipur or Alwar, where lake Dvaitavana must be placed. On the Jumna we hear at the end of the period of the Salvas, under king Yaugandhari, probably in close touch with the Kuru-Pañchāla people.
