The minor historical literature of this period displays on the other hand, amidst many insignificant and forgotten productions, one treatise of the first rank - the Memoirs of Caesar, or rather the Military Report of the democratic general to the people from whom he had received his commission. The finished section, and that which alone was published by the author himself, describing the Celtic campaigns down to 702, is evidently designed to justify as well as possible before the public the formally unconstitutional enterprise of Caesar in conquering a great country and constantly increasing his army for that object without instructions from the competent authority; it was written and given forth in 703, when the storm broke out against Caesar in Rome and he was summoned to dismiss his army and answer for his conduct[32]. The author of this vindication writes, as he himself says, entirely as an officer and carefully avoids extending his military report to the hazardous departments of political organization and administration.

His incidental and partisan treatise cast in the form of a military report is itself a piece of history like the bulletins of Napoleon, but it is not, and was not intended to be, a historical work in the true sense of the word; the objective form which the narrative assumes is that of the magistrate, not that of the historian. But in this modest character the work is masterly and finished, more than any other in all Roman literature. The narrative is always terse and never scanty, always simple and never careless, always of transparent vividness and never strained or affected. The language is completely pure from archaisms and from vulgarisms - the type of the modern urbanitas. In the Books concerning the Civil War we seem to feel that the author had desired to avoid war and could not avoid it, and perhaps also that in Caesar's soul, as in every other, the period of hope was a purer and fresher one than that of fulfilment; but over the treatise on the Gallic war there is diffused a bright serenity, a simple charm, which are no less unique in literature than Caesar is in history.

Of a kindred nature were the letters interchanged between the statesmen and literati of this period, which were carefully collected and published in the following epoch; such as the correspondence of Caesar himself, of Cicero, Calvus and others. They can still less be numbered among strictly literary performances; but this literature of correspondence was a rich store-house for historical as for all other research, and the most faithful mirror of an epoch in which so much of the worth of past times and so much spirit, cleverness, and talent were evaporated and dissipated in trifling.

A journalist literature in the modern sense was never formed in Rome; literary warfare continued to be confined to the writing of pamphlets and, along with this, to the custom generally diffused at that time of annotating the notices destined for the public in places of resort with the pencil or the pen. On the other hand subordinate persons were employed to note down the events of the day and news of the city for the absent men of quality; and Caesar as early as his first consulship took fitting measures for the immediate publication of an extract from the transactions of the senate. From the private journals of those Roman penny-a-liners and these official current reports there arose a sort of news-sheet for the capital (acta diurna), in which the resume of the business discussed before the people and in the senate, and births, deaths, and such like were recorded. This became a not unimportant source for history, but remained without proper political as without literary significance.

To subsidiary historical literature belongs of right also the composition of orations. The speech, whether written down or not, is in its nature ephemeral and does not belong to literature; but it may, like the report and the letter, and indeed still more readily than these, come to be included, through the significance of the moment and the power of the mind from which it springs, among the permanent treasures of the national literature. Thus in Rome the records of orations of a political tenor delivered before the burgesses or the jurymen had for long played a great part in public life; and not only so, but the speeches of Gaius Gracchus in particular were justly reckoned among the classical Roman writings. But in this epoch a singular change occurred on all hands.

The composition of political speeches was on the decline like political speaking itself. The political speech in Rome, as generally in the ancient polities, reached its culminating point in the discussions before the burgesses; here the orator was not fettered, as in the senate, by collegiate considerations and burdensome forms, nor, as in the judicial addresses, by the interests - in themselves foreign to politics - of the accusation and defence; here alone his heart swelled proudly before the whole great and mighty Roman people hanging on his lips. But all this was now gone. Not as though there was any lack of orators or of the publishing of speeches delivered before the burgesses; on the contrary political authorship only now waxed copious, and it began to become a standing complaint at table that the host incommoded his guests by reading before them his latest orations. Publius Clodius had his speeches to the people issued as pamphlets, just like Gaius Gracchus; but two men may do the same thing without producing the same effect. The more important leaders even of the opposition, especially Caesar himself, did not often address the burgesses, and no longer published the speeches which they delivered; indeed they partly sought for their political fugitive writings another form than the traditional one of contione, in which respect more especially the writings praising and censuring Cato[33] are remarkable. This is easily explained. Gaius Gracchus had addressed the burgesses; now men addressed the populace; and as the audience, so was the speech. No wonder that the reputable political author shunned a dress which implied that he had directed his words to the crowd assembled in the market-place of the capital.

While the composition of orations thus declined from its former literary and political value in the same way as all branches of literature which were the natural growth of the national life, there began at the same time a singular, non-political, literature of pleadings. Hitherto the Romans had known nothing of the idea that the address of an advocate as such was destined not only for the judges and the parties, but also for the literary edification of contemporaries and posterity; no advocate had written down and published his pleadings, unless they were possibly at the same time political orations and in so far were fitted to be circulated as party writings, and this had not occurred very frequently.

Even Quintus Hortensius (640-704), the most celebrated Roman advocate in the first years of this period, published but few speeches and these apparently only such as were wholly or half political. It was his successor in the leadership of the Roman bar, Marcus Tullius Cicero (648-711) who was from the outset quite as much author as forensic orator; he published his pleadings regularly, even when they were not at all or but remotely connected with politics. This was a token, not of progress, but of an unnatural and degenerate state of things. Even in Athens the appearance of non-political pleadings among the forms of literature was a sign of debility; and it was doubly so in Rome, which did not, like Athens, by a sort of necessity produce this malformation from the exaggerated pursuit of rhetoric, but borrowed it from abroad arbitrarily and in antagonism to the better traditions of the nation. Yet this new species of literature came rapidly into vogue, partly because it had various points of contact and coincidence with the earlier authorship of political orations, partly because the unpoetic, dogmatical, rhetorizing temperament of the Romans offered a favourable soil for the new seed, as indeed at the present day the speeches of advocates and even a sort of literature of law-proceedings are of some importance in Italy.
