In the camp of Mithridates there was a Dandarian prince named Olthacus (the Dandarians are a tribe of barbarians dwelling about Lake Maeotis), a man conspicuous as a soldier for qualities of strength and boldness, of a most excellent judgment, and withal affable in address and of insinuating manners. This man was always in emulous rivalry for the precedence with a fellow prince of his tribe, and so was led to undertake a great exploit for Mithridates, namely, the murder of Lucullus. The king approved of his design, and purposely inflicted upon him sundry marks of disgrace, whereupon, pretending to be enraged, he galloped off to Lucullus, who gladly welcomed him, since there was much talk of him in the camp. After a short probation, Lucullus was so pleased with his shrewdness and zeal, that he made him a table companion, and at last a member of his council. Now when the Dandarian thought his opportunity had come, he ordered his slaves to lead his horse outside the camp, while he himself, at mid-day, when the soldiers were lying around enjoying their rest, went to the general’s tent. He thought no one would deny entrance to a man who was an intimate of the general, and said he brought him certain messages of great importance. And he would have entered without let or hindrance, had not sleep, the destroyer of many generals, saved Lucullus. For it chanced that he was asleep, and Menedemus, one of his chamberlains, who stood at the tent-door, told Olthacus that he had come at an inopportune time, since Lucullus had just betaken himself to rest after his long watching and many hardships. Olthacus did not retire at the bidding of Menedemus, but declared that even in spite of him he would go in, since he wished to confer with the general on urgent business of great importance. Then Menedemus got angry, declared that nothing was more urgent than the preservation of Lucullus, and pushed the man away with both hands. Then Olthacus, in fear, left the camp, took horse, and rode off to the camp of Mithridates, without effecting his purpose. So true is it that in active life, as well as in sickness, it is the critical moment which gives the scales their saving or their fatal inclination.
