According to Tacitus, Tiberius declared before the Senate that he observed all of the deeds and pronouncements of Augustus as if they were law (Ann. 4.37). This chapter explores the degree to which that statement is true and the consequences of Tiberius’ adherence to Augustan precedents. I begin with an overview of Tiberius’ relationship with the Senate. I then examine the much criticized fiscal policies of Tiberius. Even those were a consequence of his reverence for Augustus and his desire to preserve Augustan precedent. Next, we examine the notion of the pax Augusta under Tiberius. Again, we see that Tiberius was bound by Augustan policy in his failure to expand the empire. Finally, we analyze the persecution of Jews, worshippers of Isis, and astrologers in the reign of Tiberius. These persecutions were prompted not only by Tiberius’ desire to follow Augustus’ precedents but also, more importantly, by attacks on the domus Augusta.
