POMPEY THE GREAT IN SPAIN.--The fires of the Civil War, though quenched in Italy, were still smouldering in Spain. Sertorius, an adherent of Marius, had there stirred up the martial tribes of Lusitania, and incited a general revolt against the power of the aristocratic government at Rome. Cnæus Pompey, a rising young leader of the oligarchy, upon whom the title of Great had already been conferred as a reward for crushing the Marian party in Sicily and Africa, was sent into Spain to perform a similar service there. For several years the war was carried on with varying fortunes. At times the power of Rome in the peninsula seemed on the verge of utter extinction. Finally, the brave Sertorius was assassinated, and then the whole of Spain was quickly regained. Pompey boasted of having forced the gates of more than eight hundred cities in Spain and Southern Gaul. Throughout all the conquered regions he established military colonies, and reorganized the local governments, putting in power those who would be, not only friends and allies of the Roman state, but also his own personal adherents. How he used these men as instruments of his ambition, we shall learn a little later. SPARTACUS: WAR OF THE GLADIATORS.--While Pompey was subduing the Marian faction in Spain, a new danger broke out in the midst of Italy. Gladiatorial combats had become, at this time, the favorite sport of the amphitheatre. At Capua was a sort of training-school, from which skilled fighters were hired out for public or private entertainments. In this seminary was a Thracian slave, known by the name of Spartacus, who incited his companions to revolt. The insurgents fled to the crater of Vesuvius, and made that their stronghold. There they were joined by gladiators from other schools, and by slaves and discontented men from every quarter. Some slight successes enabled them to arm themselves with the weapons of their enemies. Their number at length increased to one hundred thousand men. For three years they defied the power of Rome, and even gained control of the larger part of Southern Italy. Four Roman armies sent against them were cut to pieces. But at length Spartacus himself was slain, and the insurgents were crushed. The rebellion was punished with Roman severity. The slaves that had taken part in the revolt were hunted through the mountains and forests, and exterminated like dangerous beasts. The Appian Way was lined with six thousand crosses, bearing aloft as many bodies--a terrible warning of the fate awaiting slaves that should dare to strike for freedom.
