292 HISTORICAL TALES. metals were melted and converted into money; of the baser metals arms were made. Onomarchus went farther than Philomelus; he not only paid his troops with the treasure, but bribed the leaders of Grecian states, and thus gained powerful friends. He was soon successfully at war, drove back his foes, and pressed his conquests till he had captured Thermopyle and invaded Thessaly. Here the Phocians came into contact with a foe dangerous to themselves and to all Greece. This foe was the celebrated Philip of Macedonia, a famous soldier who was to play a leading part in the subse- quent game. He had long been paving the way to the conquest of Greece, and the Sacred War gave him just the opportunity he wanted. Macedonia lay north of Greece. Its people were not Greeks, nor like Greeks in their customs. They lived in the country, not in cities, and had little or none of the culture of Greece. But they were the stuff from which good soldiers are made. Hitherto this country had been hardly thought of as an ele- ment in the Grecian problem. Its kings were des- pots who had been kept busy with their foes at home. But now aking had arisen of wider views and larger mould. Philip had spent his youth in Thebes, where he had learned the art of war under Epaminondas. On coming to the throne he quickly proved himself a great soldier and a keen and cunning politician. By dint of war and trickery he rapidly spread his domin- ions until all his home foes were subdued, Macedonia was greatly extended, and Thessaly, the most north- ern state of Greece, was overrun.
