Of these Demetrius alone is known to the Greek historians¹, whose statements as to his Indian conquests are confirmed, though scarcely supplemented, by the evidence of coins. The district, in which his bilingual square copper coins were struck, has not been determined; and all that can be said of his round coins, with types 'Elephant's head: Caduceus' and Greek legend only, is that they were directly copied by the Çaka king Maues, and that they must therefore have been in circulation in the lower Kābul valley or in N.W. India (Pl. VI, 1, 2).
