How far Metellus was terrified and at what rate he esteemed him, he plainly declared, when he offered by proclamation an hundred talents and twenty thousand acres of land to any Roman that should kill him, and leave, if he were banished, to return; attempting villainously to buy his life by treachery, when he despaired of ever being able to overcome him in open war. When once he gained the advantage in a battle against Sertorius, he was so pleased and transported with his good fortune, that he caused himself to be publicly proclaimed imperator; and all the cities which he visited received him with altars and sacrifices; he allowed himself, it is said, to have garlands placed on his head, and accepted sumptuous entertainments, at which he sat drinking in triumphal robes, while images and figures of victory were introduced by the motion of machines, bringing in with them crowns and trophies of gold to present to him, and companies of young men and women danced before him, and sang to him songs of joy and triumph. By all which he rendered himself deservedly ridiculous, for being so excessively delighted and puffed up with the thoughts of having followed one who was retiring of his own accord, and for having once had the better of him whom he used to call Sylla's runaway slave, and his forces, the remnant of the defeated troops of Carbo.
Sertorius, meantime, showed the loftiness of his temper in calling together all the Roman senators who had fled from Rome, and had come and resided with him, and giving them the name of a senate; and out of these he chose praetors and quaestors, and adorned his government with all the Roman laws and institutions. And though he made use of the arms, riches, and cities of the Spaniards, yet he would never, even in word, remit to them the imperial authority, but set Roman officers and commanders over them, intimating his purpose to restore liberty to the Romans, not to raise up the Spaniard's power against them. For he was a sincere lover of his country, and had a great desire to return home; but in his adverse fortune he showed undaunted courage, and behaved himself towards his enemies in a manner free from all dejection and mean-spiritedness; and when he was in his prosperity, and in the height of his victories, he sent word to Metellus and Pompey that he was ready to lay down his arms and live a private life if he were allowed to return home, declaring that he had rather live as the meanest citizen in Rome than, exiled from it, be supreme commander of all other cities together. And it is thought that his great desire for his country was in no small measure promoted by the tenderness he had for his mother, under whom he was brought up after the death of his father, and upon whom he had placed his entire affection. After that his friends had sent for him into Spain to be their general, as soon as he heard of his mother's death he had almost cast away himself and died for grief; for he lay seven days together continually in his tent, without giving the word, or being seen by the nearest of his friends; and when the chief commanders of the army and persons of the greatest note came about his tent, with great difficulty they prevailed with him at last to come abroad, and speak to his soldiers, and to take upon him the management of affairs, which were in a prosperous condition. And thus, to many men's judgment, he seemed to have been in himself of a mild and compassionate temper, and naturally given to ease and quietness, and to have accepted of the command of military forces contrary to his own inclination, and not being able to live in safety otherwise, to have been driven by his enemies to have recourse to arms, and to espouse the wars as a necessary guard for the defence of his person.
His negotiations with King Mithridates further argue the greatness of his mind. For when Mithridates recovering himself from his overthrow by Sylla, like a strong wrestler that gets up to try another fall, was again endeavouring to re-establish his power in Asia, at this time the great fame of Sertorius was celebrated in all places;and when the merchants who came out of the western parts of Europe, bringing these, as it were, among their other foreign wares, had filled the kingdom of Pontus with their stories of his exploits in war, Mithridates was extremely desirous to send an embassy to him, being also highly encouraged to it by the boastings of his flattering courtiers, who, comparing Mithridates to Pyrrhus, and Sertorius to Hannibal, professed that the Romans would never be able to make any considerable resistance against such great forces, and such admirable commanders, when they should be set upon on both sides at once, on one by the most warlike general, and on the other by the most powerful prince in existence.
