*Character and policy.* Tiberius was now fifty-six years of age. He had spent the greater part of his life in the public service, and consequently had a full appreciation of the burden of responsibility which the princeps must assume. He was the incarnation of the old Roman sense of duty to the state, and at the same time exhibited the proud reserve of the Roman patricians. Stern in his maintenance of law and order, he made an excellent subordinate, but when called upon to guide the policy of state, he displayed hesitation and lack of decision. The incidents of his marriage with Julia and his exile had rendered him bitter and suspicious, and he utterly lacked the personal charm and adaptability of his predecessor. Thus he was temperamentally unsuited to the position he was called upon to fill and this was responsible for his frequent misunderstandings with the Senate. Such an incident occurred in the meetings of the Senate after the death of Augustus. Tiberius, conscious of his unpopularity, sought to have the Senate press upon him the appointment as the successor of Augustus, and so feigned reluctance to accept, a course which made the senators suspect that he was laying a trap for possible rivals. Yet there was no princeps who tried more conscientiously to govern in the spirit of Augustus, or upheld more rigidly the rights and dignity of the Senate. At the beginning of his principate he transferred from the Assembly to the Senate the right of the election to the magistracies, thus relieving the senators from the expense and annoyance of canvassing the populace.
*Mutinies in Illyricum and on the Rhine.* Two serious mutinies followed the accession of Tiberius, one in the army stationed in Illyricum, the other among the legions on the Rhine. Failure to discharge those who had completed their terms of service and the severity of the service itself were the grounds of dissatisfaction. The Illyrian mutiny was quelled by the praetorian prefect Lucius Aelius Seianus; the army of the Rhine was brought back to its allegiance by Germanicus, the son of Drusus, whom Tiberius had adopted at the command of Augustus in 4 A. D. He had married Agrippina, daughter of Agrippa and Julia, and was looked upon as the heir of Tiberius in preference to the latter's younger and less able son, Drusus.
