“ Marius, when in his sixth consulship, gave rise to the Civil war; for when Sulla. the consul, was sent to conduct the war against Mithridates, who had possessed himself of Asia and Achaia, and delayed his army for a short time in Campania, in order that the remains of the Social war, of which we have just spoken, and which had been carried on within the limits of Italy, might be extinguished, Marius showed himself ambitious to be appointed to the Mithridatic war. Sulla, being incensed at this conduct, marched to Rome with his army. There he fought with Marius and Sulpicius ”

“ Sulla besieged Archelaus at the Piraeeus near Athens, and took the city itself. Engaging afterwards in battle with Archelaus, he gave him such a defeat, that out of a hundred and twenty thousand of the army of Archelaus scarce ten remained; while of that of Sulla only fourteen were killed. Mithridates, on receiving intelligence of this battle, sent seventy thousand chosen troops out of Asia to Archelaus, with whom Sulla came again to an engagement. In the first battle twenty thousand of the enemy were slain, and Diogenes, the son of Archelaus ”

“ He next marched into Bithynia and Paphlagonia, driving out the kings, Pylaemenes and Nicomedes, who were also in alliance with the Romans. He then hastened to Ephesus, and sent letters into all parts of Asia, with directions that wherever any Roman citizens should be found, they should all be put to death the same day. ”
