Eutropius, Breviarium 7.8 "From that period he held the government as sole ruler for forty-four years, for during the twelve previous years he had held it in conjunction with Antony and Lepidus. Thus from the beginning of his reign to the end were fifty-six years."
Jerome, Chronichon, 184th Olympiad. "2nd [ruler] of the Romans, Octavianus Caesar Augustus reigned for 56 years and 6 months; from whom the kings [basileus] of the Romans are called Augusti."
Paterculus (II, 80–90), for example, only uses princeps, but the English text translates the word directly as "emperor". Livy (I. 19) calls Augustus imperator once, but he also uses the term when writing about other generals (II. 39ff).
Res GestaeI.7, "For ten years in succession I was one of the triumvirs for the re-establishment of the constitution. To the day of writing this [June/July AD 14] I have been princeps senatus for forty years." Augustus thus dates his tenure as princeps from 27 BC. He also only counts his de jure tenure as triumvir.
