Ancient historians give as a reason for Tiberius' retirement to Capri his inability to endure his mother any longer. Until AD 22 there had, according to Tacitus, been "a genuine harmony between mother and son, or a hatred well concealed;" Dio tells us that at the time of his accession already Tiberius heartily loathed her. In AD 22 she had fallen ill, and Tiberius hastened back to Rome in order to be with her. But in AD 29 when she finally fell ill and died, he remained on Capri, pleading pressure of work and sending Caligula to deliver the funeral oration. Suetonius adds the macabre detail that "when she died... after a delay of several days, during which he held out hope of his coming, was at last buried because the condition of the corpse made it necessary...". Divine honors he also vetoed, stating that this was in accord with her own instructions. Later he vetoed all the honors the Senate had granted her after her death and cancelled the fulfillment of her will.
