From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
But people could no longer shut their eyes, however willing they might be to do so, when Pompeius did not select for his colleague in the consulship his former father-in-law Caesar, as was fitting in the circumstances of the case and was in many quarters demanded, but associated with himself a puppet wholly dependent on him in his new father-in-law Scipio;(14) and still less, when Pompeius at the same time got the governorship of the two Spains continued to him for five years more, that is to 709, and a considerable fixed sum appropriated from the state-chest for the payment of his troops, not only without stipulating for a like prolongation of command and a like grant of money to Caesar, but even while labouring ulteriorly to effect the recall of Caesar before the term formerly agreed on through the new regulations which were issued at the same time regarding the holding of the governorships.
14. Cf. V. VIII. Humiliation of the Republicans
These encroachments were unmistakeably calculated to undermine Caesar's position and eventually to overthrow him. The moment could not be more favourable. Caesar had conceded so much to Pompeius at Luca, only because Crassus and his Syrian army would necessarily, in the event of any rupture with Pompeius, be thrown into Caesar's scale; for upon Crassus--who since the times of Sulla had been at the deepest enmity with Pompeius and almost as long politically and personally allied with Caesar, and who from his peculiar character at all events, if he could not himself be king of Rome, would have been content with being the new king's banker--Caesar could always reckon, and could have no apprehension at all of seeing Crassus confronting him as an ally of his enemies.
