Regulation of Asiatic Affairs
Sulla determined to leave these two legions, whom he did not trust for the impending war, behind in Asia, where the fearful crisis left for long its lingering traces in the several cities and districts. The command of this corps and the governorship of Roman Asia he committed to his best officer, Lucius Licinius Murena. The revolutionary measures of Mithradates, such as the liberation of the slaves and the annulling of debts, were of course cancelled; a restoration, which in many places could not be carried into effect without force of arms.
The towns of the territory on the eastern frontier underwent a comprehensive reorganization, and reckoned from the year 670 as the date of their being constituted. Justice moreover was exercised, as the victors understood the term. The most noted adherents of Mithradates and the authors of the massacre of the Italians were punished with death. The persons liable to taxes were obliged immediately to pay down in cash according to valuation the whole arrears of tenths and customs for the last five years; besides which they had to pay a war-indemnity of 20,000 talents (4,800,000 pounds), for the collection of which Lucius Lucullus was left behind.
