in the campaigns and victories of Trajan, who, at the time of his elevation to the imperial power, was at the head of the Roman armies in Germany, where he also remained for a year or more after his accession to the throne, till he had received the submission of the hostile tribes and wiped away the disgrace which the Germans, beyond any other nation of that age, had brought upon the Roman arms. Such a people, at such a time, could not fail to be an object of deep interest at Rome. This was the time when Tacitus published his work on Germany; and such are believed to have been the motives and the circumstances, which led to the undertaking. His grand object was not to point a satire or to compass a political end, but as he himself informs us (§ 27), to treat of the origin and manners, the geography and history, of the German Tribes. The same candor and sincerity, the same correctness and truthfulness, which characterize the Histories, mark also the work on Germany. The author certainly aimed to speak the truth, and nothing but the truth, on the subject of which he treats. Moreover, he had abundant means of knowing the truth, on all the main points, in the character and history of the Germans. It has even been argued from such expression as _vidimus_ (§ 8), that Tacitus had himself been in Germany, and could, therefore, write from personal observation. Bnt the argument proceeds on a misinterpretation of his language (cf. note in _loc. cit_.). And the use of _accepimus_ (as in § 27), shows that he derived his information from others. But the Romans had been in constant intercourse and connection, civil or military, with the Germans, for two hundred years. Germany furnished a wide theatre for their greatest commanders, and a fruitful theme for their best authors, some of whom, as Julius Caesar (to whom Tacitus particularly refers, 28), were themselves the chief actors in what they relate. These authors, some of whose contributions to the history of Germany are now lost (e.g. the elder Pliny, who wrote twenty books on the German wars), must have all been in the hands of Tacitus, and were, doubtless, consulted by him; not, however, as a servile copyist, or mere compiler (for he sometimes differs from his authorities, from Caesar even, whom he declares to be the best of them), but as a discriminating and judicious inquirer. The account of German customs and institutions may, therefore, be relied on, from the intrinsic credibility of the author. It receives confirmation, also, from its general accordance with other early accounts of the Germans, and with their better known subsequent history, as well as from its strong analogy to the well-known habits of our American aborigines, and other tribes in a like stage of civilization (cf. note, § 15). The geographical details are composed with all the accuracy which the ever-shifting positions and relations of warring and wandering tribes rendered possible in the nature of the case (cf. note, § 28).
