v1.c31.48

At some time during the period when the first three Çaka kings were establishing their empire in India, Vonones was reigning as suzerain over the kingdoms of eastern Irān with the same imperial title, ‘Great King of Kings.’ It is inconceivable that such a dignity should have been usurped in this region so long as it remained under the suzerainty of Parthia. Vonones, like Maues, must, therefore, be later than the reign of Mithradates II the Great (123–88 b.c.)—precisely how much later must for the present remain uncertain.
