The Works of Tacitus (C. Cornelii Taciti Opera)

...Verginius Rufus, who had defeated Vindex and had constantly refused the empire offered to him by the German legions, was chosen as colleague in the consulship, but Trajan was also sent into lower Germany with command, and by him, discipline of the soldiers was restored, the trans-Rhenish peoples were warded off from crossing the Rhine, and he acted so happily that in the following year he was adopted by the same Nerva and was honored in the senate with the title of Caesar Germanicus. See Dio 68, 2, 3; Pliny, Panegyricus 9 and 14. For in the booklet of Tacitus itself, some things are found which pertain to the first years of the empire administered by Trajan from the year of Christ 98 to the year 117. To this seem to be referred, first, the very words just transcribed from chapter 37, in which Trajan is called Emperor, who nevertheless had entered his second consulship before the principate; then those things which are read in α, chapter 1, "concerning certain peoples recently known" (the Burii or Burri, Marsigni, Gothini, Osi, and others, regarding whom see chapter 43) and kings, "whom the war revealed," namely the war managed by the Emperor Trajan against the Dacians and their king Decebalus from the year 853—856 A.U.C. (100—103 AD), which the Burii and other allies of this king had persuaded him not to undertake. See Dio 68, 8. β, chapter 29, "concerning the established boundary and the advanced garrisons," forts, ramparts, and fortifications restored by Trajan along the Danube, Rhine, and Main, so that the impulses of the Germans might be restrained. Cf. on Tacitus, Annals 1, 50, 1; Wilhelm's Germania pp. 291—310; the words of Aelius Spartianus in Hadrian c. 12: "Through those times and frequently elsewhere in many places, in which barbarians are divided not by rivers but by boundaries, he separated the barbarians with large stakes thrown and connected from the bottom in the manner of a wall-like fence," and especially Eutropius 8, 2: "Trajan spread the boundaries of the Roman Empire, which after Augustus had been defended rather than nobly expanded, far and wide: he repaired cities (garrisons, forts, fortifications) across the Rhine in Germany." γ, chapter 33, concerning the Bructeri who were utterly destroyed, regarding which matter Pliny Epistulae 2, 7 says, magnified: "Vestricius Spurinna brought the king of the Bructeri into the kingdom by force and arms, and with the war displayed, he conquered the most ferocious tribe—which is the most beautiful kind of victory—by terror." δ, chapter 41, concerning the most splendid colony of the province of Raetia.
