From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
Afranius had but recently occupied a very similar position, without thereby acquiring any special importance; several provinces at once had been of late years repeatedly placed under one governor, and often far more than four legions had been united in one hand; as matters were again quiet beyond the Alps and prince Ariovistus was recognized by the Romans as a friend and neighbour, there was no prospect of conducting a war of any moment there. It was natural to compare the position which Pompeius had obtained by the Gabinio-Manilian law with that which Caesar had obtained by the Vatinian; but the comparison did not turn out to Caesar's advantage. Pompeius ruled over nearly the whole Roman empire; Caesar over two provinces.
Pompeius had the soldiers and the treasures of the state almost absolutely at his disposal; Caesar had only the sums assigned to him and an army of 24,000 men. It was left to Pompeius himself to fix the point of time for his retirement; Caesar's command was secured to him for a long period no doubt, but yet only for a limited term. Pompeius, in fine, had been entrusted with the most important undertakings by sea and land; Caesar was sent to the north, to watch over the capital from upper Italy and to take care that Pompeius should rule it undisturbed.
