As a source, the "Res Gestae" is not fully accurate. Whilst not lying, he doesn't mention some things that he did like the proscriptions of his enemies. He refers to his rival Marc Antony as 'a faction'. The inscription says much about the money he spent on the people, Rome and the empire. It also says frequently that he has "restored the republic" and only gains his titles because of the universal support from the people and, most importantly, the Senate.
