Designs of Caesar in This Arrangement
That this whole settlement of the pending questions proceeded, not from a compromise among independent and rival regents meeting on equal terms, but solely from the good will of Caesar, is evident from the circumstances. Pompeius appeared at Luca in the painful position of a powerless refugee, who comes to ask aid from his opponent. Whether Caesar chose to dismiss him and to declare the coalition dissolved, or to receive him and to let the league continue just as it stood--Pompeius was in either view politically annihilated. If he did not in this case break with Caesar, he became the powerless client of his confederate.
If on the other hand he did break with Caesar and, which was not very probable, effected even now a coalition with the aristocracy, this alliance between opponents, concluded under pressure of necessity and at the last moment, was so little formidable that it was hardly for the sake of averting it that Caesar agreed to those concessions. A serious rivalry on the part of Crassus with Caesar was utterly impossible. It is difficult to say what motives induced Caesar to surrender without necessity his superior position, and now voluntarily to concede--what he had refused to his rival even on the conclusion of the league of 694, and what the latter had since, with the evident design of being armed against Caesar, vainly striven in different ways to attain without, nay against, Caesar's will--the second consulate and military power.
