INTBODUCTION 5 the Greek conquest of the North-West Panjab was probably effected towards the latter end of the reign of Euthydemos, or during the early career of his son Demetrios. The coins of Diodotos and Euthydemos are Greek money of the Attic standard. The Greek kings of Bactriana steadily adhered to the monetary system of Athens, which had already been adopted by Alexander and by his immediate successors in Syria, But the Greek kings of India, from the very first, departed from the Attic system in the mass of their copper money, as shown in the coins of Pantaloon and Agathokles, which are of the same weight, and of the same square shape, as the indigenous copper coins of Taxila. The copper money of Pantaleon's successors is usually square or rectangular, but the only square silver pieces are hemidrachms of Apollodotos and Philoxenos. The first coin to exhibit legends in both the Greek and the Kharosthi scripts, is a square copper coin of Demetrios. There is a good specimen in this Collection. Demetrios is known as the first king of Bactria and of India, that is to say, he held sway both in Bactria proper, and also in Gandhara and the regions on the side of India where Kharosthi was used. Eukratides struck coins of the purely Greek type and weight, and also of the bilingual Indian type, in silver and in copper, while both types are found in silver only of Heliokles and of Antialkidas. The succeeding princes coined bilingual money alone in silver and copper. In the absence of money of the Greek type, it may be assumed that their power was confined to the regions about the North-West Indian frontier. Gold coins of the Greek standard till the time of Eukratides are known, though very scarce. The discovery of a twenty-stater piece of Eukratides at Bukhara caused a sensation in the numismatic world about sixty years ago. The medal itself is in the Cabinet de Frances Bibliothfeque Nationale, Paris. It is a remarkable fact that after Eukratides a gold currency of any Greek prince up to and including the last king Hermaios is absolutely unknown.1 We are told that Persian darics and Eoman aurei found their way to India in great quantities, but no darics were struck in Persia after 330 B.C., and gold was not coined at Eome in any quantity before the early Empire, There is nothing to guide us to the history of the successors of Eukratides except their coins. It is conjectured that after his death 1 There is a gold stater in the British Museum Collection which has been tenta- tively assigned to Menander. The obverse design is the helmeted bust of a Mng? and that on the reverse side is a standing owl; there are no inscriptions. The figure of the owl is of very inferior artistic merit, and cannot bear comparison witlx that on the owl hemidrachnt of Menander. In the absence of any legend I do not think that any definite attribution can be made. The coin may be a contemporaneous imitation. 1535 B
