f Drusus, resulting in the
subjection of the German tribes from the Rhine to the Elbe, were too
rapid to be lasting, they brought home the fact of the existence of the
Romans to many who had never heard their name. For his victories he
received the title of Germanicus. He married Antonia, the daughter of
Marcus Antonius the triumvir, by whom he had three children: Germanicus,
adopted by Tiberius; Claudius, afterwards emperor; and a daughter
Livilla.

The chief ancient authorities for the life of Drusus are Dio Cassius,
the epitomes of Livy, Suetonius (_Claudius_), Tacitus (portions of the
_Annals_), Florus (whose chief source is Livy), Velleius Paterculus,
and the _Consolatio ad Liviam_. The German campaigns were described in
the last books of Livy and the lost _Bella Germaniae_ of the elder
Pliny. As would naturally be expected, they have produced an extensive
literature in Germany, J. Asbach's "Die Feldzuge des Nero Claudius
Drusus" (_Rhein. Jahrb._ lxxxv. 14-30) being especially recommended;
see also Mommsen's _History of the Roman Provinces_, i.; Merivale,
_History of the Romans under the Empire_, ch. 36; A. Stein in
Pauly-Wissowa's _Realencyclopadie_ (1899), where other authorities are
given; J. C. Tarver, _Tiberius the Tyrant_ (1902).

the emperor Tiberius by his first wife Vipsania Agrippina. After having
held several curule offices, he was consul elect in A.D. 14, the year of
Augustus's death. His father, on his accession to the throne,
immediately sent him to put down a mutiny of the troops in Pannonia, a
task which he successfully accomplished (Tacitus, _Annals_, i. 24-30).
As governor of Illyricum (17), he set the Germanic tribes against one
another, and encouraged Catualda, chief of the Gothones, to drive out
Marbod (Maroboduus), king of the Marcomanni. On his return Drusus was
consul a second time (21) and in the following year received the
tribunician authority from Tiberius, which practically indicated him as
heir to the throne. Sejanus, who also aspired to the supreme power,
determined to remove Drusus. He endeavoured to poison Tiberius's mind
against him, seduced Drusus's wife and persuaded her to assist him in
murdering her hu
