16. DRUSUS CAESAR, commonly called by modern writers Drusus Junior, to distinguish him from his uncle Drusus, the brother of Tiberius (No. 11), was the son of the emperor Tiberius by his first wife, Vipsania, who was the daughter of Agrippa by Pomponia, the daughter of Atticus. Thus, his great-grandfather was only a Roman knight, and his descent on the mother's side was by no means so splendid as that of his cousin Germanicus, who
In A. D. 10 he was quaestor. After the death of Augustus, A. D. 14, (in whose praise he read a funeral oration before the rostra,) he was sent into Pannonia to quell the mutiny of the legions. This task he performed with address, and with the vigour of innate nobility. He ordered the execution of the leaders, and the superstitious fears produced in the minds of the soldiers by an opportune eclipse of the moon aided his efforts. (Tac. Ann. 1.24-30.) After his return to Rome, he was made consul in A. D. 15, and, at the gladiatorial games which he gave in co injunction with Germanicus (his brother by adoption), he made himself so remarkable by his sanguinary taste for vulgarblood, as even to offend the squeamishness of Roman spectators. (Ann. 1.76.) He degraded the dignity of his office by his excesses, and by his fondness for players, whom he encouraged in their factious riots, in opposition to his father's laws. In one of his ordinary ebullitions of passion, he pummelled a Roman knight, and, from this exhibition of his pugilistic propensities, obtained the nickname of Castor. (D. C. 57.14.) In the following year Tiberius sent him to Illyricum, not only to teach him the art of war, and to make him popular with the soldiery, but to remove him from the dissipations of the city. It is not easy to determine the exact scene of his operations, but he succeeded in fomenting dissension among the Germanic tribes, and destroyed the power of Maroboduus. For these successes an ovation was decreed to him by the senate. In the year A. D. 21, he was consul a second time, and the emperor was his colleague. In A. D. 22, he was promoted to the still higher dignity of the " tribunicia potestas," a title devised by Augustus to avoid the obloquy attending the name of king or dictator. By this title subsequent emperors counted the years of their reign upon their coins. It rendered the power of intercession and the sacrosanct character of tribunus plebis compatible with patrician birth. To confer it upon Drusus was clearly to point him out as the intended successor to the empire. (Ann. 3.56.)
On one occasion Drusus, who regarded Sejanus as a rival, gave way to the impetuosity of his temper, and struck the favourite upon the face. The ambition of Sejanus had taught him to aspire to the empire, and to plot against all who stood in his way. The desire of vengeance was now added to the stimulus of ambition. He turned to Livia, the wife of Drusus, seduced her affections, persuaded the adulteress to become the murderer of her hus band, and promised that he would marry her when Drusus was got rid of. Her physician Eudemus was made an accomplice in the conspiracy, and a poison was administered to Drusus by the eunuch Lygdus, which terminated his life by a lingering disease, that was supposed at the time to be the consequence of intemperance. (Suet. Tib. 62.) This occurred in A. D. 23, and was first brought to light eight years afterwards, upon the information of Apicata, the wife of Sejanus, supported by the confessions, elicited by torture, of Eudemus and Lygdus. (Ann. 4.3, 8, 11.)
The funeral of Drusus was celebrated with the greatest external honours, but the people were pleased at heart to see the chance of succession revert to the house of Germanicus. Tiberius bore the death of his only son with a cool equanimity which indicated a want of natural affection.
