Men of judgment will not require any proof, either that Caesar intended to engraft on the commonwealth his supreme power, and this not merely for a few years or even as a personal office for an indefinite period somewhat like Sulla’s regency, but as an essential and permanent organ; or that he selected for the new institution an appropriate and simple designation; for, if it is a political blunder to create names without substantial meaning, it is scarcely a less error to set up the substance of plenary power without a name. Only it is not easy to determine what definitive formal shape Caesar had in view; partly because in this period of transition the ephemeral and the permanent buildings are not clearly discriminated from each other, partly because the devotion of his clients which already anticipated the nod of their master loaded him with a multitude—offensive doubtless to himself—of decrees of confidence and laws conferring honours. Least of all could the new monarchy attach itself to the consulship, just on account of the collegiate character that could not well be separated from this office; Caesar also evidently laboured to degrade this hitherto supreme magistracy into an empty title, and subsequently, when he undertook it, he did not hold it through the whole year, but before the year expired gave it away to personages of secondary rank. The dictatorship came practically into prominence most frequently and most definitely, but probably only because Caesar wished to use it in the significance which it had of old in the constitutional machinery—as an extraordinary presidency for surmounting extraordinary crises. On the other hand it was far from recommending itself as an expression for the new monarchy, for the magistracy was inherently clothed with an exceptional and unpopular character, and it could hardly be expected of the representative of the democracy that he should choose for its permanent organization that form, which the most gifted champion of the opposing party had created for his own ends.
The new name of Imperator, on the other hand, appears in every respect by far more appropriate for the formal expression of the monarchy; just because it is in this application(13) new, and no definite outward occasion for its introduction is apparent. The new wine might not be put into old bottles; here is a new name for the new thing, and that name most pregnantly sums up what the democratic party had already expressed in the Gabinian law, only with less precision, as the function of its chief—the concentration and perpetuation of official power (-imperium-) in the hands of a popular chief independent of the senate. We find on Caesar’s coins, especially those of the last period, alongside of the dictatorship the title of Imperator prevailing, and in Caesar’s law as to political crimes the monarch seems to have been designated by this name. Accordingly the following times, though not immediately, connected the monarchy with the name of Imperator. To lend to this new office at once a democratic and religious sanction, Caesar probably intended to associate with it once for all on the one hand the tribunician power, on the other the supreme pontificate.
