Perhaps no country in the world has had such a chequered and miserable history as the pleasant island of Sicily with its rich volcanic soil. For four hundred years it had been mainly Greek. The eastern end, at least, had been scattered with important city-states which, under the leadership of Syracuse, had waged incessant conflict with the Carthaginian invaders in their western strongholds. We have seen how the Romans finally drove out the Semitic element and conquered the Greeks. During the latter part of republican history the island had been of vital importance to Rome as supplying through its tribute the chief part of the corn-supply. At the same time it had been cruelly exploited and oppressed by Roman governors like Verres. Then during the civil wars Sextus Pompeius had made it his head-quarters, and it had been laid under heavy contributions by both sides. Messina, its richest town, had been the scene of a sack and massacre. No country had more to hope from the Pax Augusta, and it now began to enjoy one of its brief periods of rest. Augustus spent the winter of 22 in Sicily at the beginning of his tour in Greece. He founded colonies at six famous cities of old. While he was in the island the Sicilians offered him a kind of round-robin of complaint against the extortion of his procurator. Augustus instantly dismissed the offender and replaced him by his own valued tutor, the philosopher Areus. It was thoroughly in accordance with his policy to put a Greek philosopher in charge of a Greek island. So far we have been surveying the treatment of that part of the Roman world which was already quite civilised and mainly Greek. We now turn to the barbarian West and North, mainly consisting of newly conquered Cæsarian provinces. In these quarters, the nearer parts of Spain and the Narbonensian province of Gaul were the only regions which could be called civilised. As soon as the provisional settlement of 27 b.c. was effected Augustus hurried away to Gaul. It was generally thought that he was on his way to conquer Britain, for that was the second of the two tasks which Julius had left to his successor. Accordingly the loyal Horace dutifully prays: serues iturum Cæsarem in ultimos orbis Britannos.[45]
