for a promise leaves no room for any further consideration.”  Accordingly Cinna sent for Marius, and the forces being distributed among them, the three had the command.  The war being finished, Cinna and Marius were filled with violence and bitterness, so that they made the evils of war as precious gold to the Romans, compared with the new state of affairs.  Sertorius alone is said to have put no person to death to gratify his vengeance, nor to have abused his power; but he was much annoyed at the conduct of Marius, and he moderated Cinna by private interviews and entreaties.  At last, the slaves whom Marius had used as allies in war, and kept as guards to protect his tyranny, becoming formidable and wealthy, partly from the grants of Marius and his direct permission; partly from their violent and outrageous treatment of their masters, whom they butchered, and then lay with their masters’ wives, and violated their children, Sertorius unable to endure any longer, speared the whole of them in their camp, to the number of four thousand.[113] VI.  But when Marius[114] had died, and Cinna shortly after was cut off, and the younger Marius, contrary to the wish of Sertorius, and by illegal means, obtained the consulship, and the Carbos and the Norbani and Scipios were unsuccessfully contending against Sulla on his march to Rome, and affairs were being ruined, partly through the cowardice and laziness of the commanders, and partly through treachery; and there was no use in his staying to see things still go on badly, owing to the want of judgment in those who had more power than himself; and finally, when Sulla, after encamping near Scipio, and holding out friendly proposals, as if peace was going to be made, had corrupted the army, though Sertorius had warned Scipio of this, and given his advice, but without effect—­altogether despairing about the city, Sertorius set out for Iberia, in order that if he should anticipate his enemies in strengthening his power there, he might offer protection to such of his friends as were unfortunate at Rome.  Sertorius, having fallen in with bad weather in the mountainous parts, was required by the barbarians to pay them a tribute, and to purchase a free passage.  His companions were much incensed at this, and declared it to be a great degradation for a Roman proconsul[115] to pay a tribute to wretched barbarians; but Sertorius cared little for what they considered disgrace, and he said that he was buying time, the rarest of things for a man who was aiming at great objects:  and so he pacified the barbarians with money, and hurrying into Iberia, got possession of the country.  He there found nations strong in numbers and fighting men, but owing to the greediness and tyranny of the governors who had from time to time been sent among them, ill-disposed to the Roman administration in general; however, he regained the good will of the chiefs by his personal intercourse with them, and the favour of the mass by remission of taxes.  But
