kingdom as governed from two capital cities 350 miles apart, but linked by a continuous river thoroughfare.”¹ A historic verisimilitude might be given to this picture by invoking the duality of the Arab régime in that same valley in the ninth century A.D., when a northern Arab principality was ruled from Multān (near enough to Harappā) and a southern from Mansūrah (near enough to Mohenjo-daro).¹ And Professor Piggott has himself cited as a possible analogy the duality of the Kushān Empire in the second century A.D., with its complementary capitals at Peshāwar and Mathurā.² The conjecture is a plausible one and is slightly supported at present by a gap which seems to separate the north-eastern and south-western groups of Indus sites on the map. This gap, however, may merely reflect inadequate exploration, and indeed, as these words are written, exploration in the State of Bikaner is vividly demonstrating the potentiality of further ground-survey.
