On the conquest of Athens by Macedon, at the end of the fourth century B.C., the autonomous Athenian coinage was largely superseded by the Macedonian regal issues, and did not recover its position until late in the next century. It was renewed in a different form, with none of the old archaism, of which the occasion was past. The coins of the new style exemplify the thin flat fabric of the period, and although the types of Athena and the owl are preserved, their arrangement is much more complicated. The new head of Athena is a copy from the colossal ivory and gold statue which Pheidias made, and on the reverse of the coins the owl and olive spray are accompanied by many new devices, of which the most remarkable are the names, symbols, and monograms of the monetary magistrates; eminent personages sometimes figure in this place. On the coins exhibited (No. =34=; fig. 12_l_) one of the officials is Antiochos, who was afterwards Epiphanes, king of Syria. In the interval between the old and new coinages, when the Athenian money was scanty, the currency was supplied by the regal issues of the Macedonian kings and their successors. Under Philip II. and his son Alexander the Great, the Macedonian monarchy extended its dominion by conquest, not only over the isolated Greek cities, but over the ancient empire of Persia. The opportunity was thus provided for a universal coinage, and it was realised in the gold and silver issues of Philip and Alexander (Nos. =35=, =36=; fig. 12_n-q_). The acquisition of the Thracian gold-mines gave Philip the means for an abundant coinage of gold, the first considerable Greek issue of the kind, which contributed in no small measure to his political success. The style of these coins of Philip is not different from that of other Greek money, except that they are inscribed with a personal name--of Philip--instead of the name of a whole people, and the types, a horse and jockey and a two-horse chariot, are also personal, as they commemorate the racing successes of the king. The fine heads on the obverse, however, are still divine, that of Zeus appearing on the silver and the young Apollo on the gold, for the idea of representing a living personage on a coin was still distant. Of this money the gold especially was struck in enormous quantities, and the types were imitated more and more crudely, as time went on, in Gaul and Britain. (_See_ the series shown in the Room of Roman Britain.) The coinage of Alexander was even more widely spread. His types were more orthodox than those of Philip: the head of Athena and a Victory on the gold, and the head of young Herakles, wrapped in the lion-skin, with a figure of Zeus enthroned, on the silver staters, although in the head of Herakles there is some suggestion of the features of Alexander. These coins were struck all over the world which Alexander conquered, and lasted after his death as the money of his successors and of
