Twenty thousand prisoners fell into his hands. With unusual humanity he spared their lives, and thinking that man was the creature of circumstances, determined to change their manner of life. They were to be removed from the sea, should cease to be sailors, and become farmers. It is possible that the old man of Corycus, whose skill in gardening Virgil celebrates in one of his Georgics, was one of the pirates whom the judicious mercy of Pompey changed into a useful citizen. A still greater success remained to be won. For more than twenty years war, occasionally intercepted by periods of doubtful peace, had been carried on between Rome and Mithridates, king of Pontus. This prince, though reduced more than once to the greatest extremities, had contrived with extraordinary skill and courage to retrieve his fortunes, and now in 67 B.C. was in possession of the greater part of his original dominion. Lucullus, a general of the greatest ability, was in command of the forces of Rome, but he had lost the confidence of his troops, and affairs were at a standstill. Pompey's friends proposed that the supreme command should be transferred to him, and the law, which Cicero supported in what is perhaps the most perfect of his political speeches[6], was passed. Pompey at once proceeded to the East. For four years Mithridates held out, but with little hope of ultimate success or even of escape. In 64, after vainly attempting to poison himself, such was the power of the antidotes by which he had fortified himself against domestic treachery (for so the story runs), he perished by the sword of one of his mercenaries. For two years more Pompey was busied in settling the affairs of the East. At last, in 61, he returned to Rome to enjoy a third triumph, and that the most splendid which the city had ever witnessed. It lasted for two days, but still the time was too short for the display of the spoils of victory. The names of no less than fifteen conquered nations were carried in procession. A thousand forts, nine hundred cities, had been taken, and the chief of them were presented by means of pictures to the eyes of the people. The revenue of the State had been almost doubled by these conquests. Ninety thousand talents in gold and silver coin were paid into the treasury, nor was this at the expense of the soldiers, whose prize money was so large that the smallest share amounted to fifty pounds. Never before was such a sight seen in the world, and if Pompey had died when it was finished, he would have been proclaimed the most fortunate of mankind. [Footnote 6: The Pro Lege Manilia.
