There was much gossip over the outcome of their expedition. Tacitus recounts the rumour that Augustus had decided to reverse his decision and make Postumus his successor. In his account, Fabius indiscreetly told his wife what had occurred during the trip, and that cost him his life. Augustus' wife, Livia, too was said to have poisoned her husband to prevent Postumus from becoming the successor and thus supplanting her son Tiberius. While modern historians, including Fox, agree that such stories are highly unlikely, there is evidence that Augustus' journey was historical. "It is the last act in Augustus' long marathon of finding and keeping an heir to the new Empire".
