I suppose I should offer some judgement about the quality of the dialogue... I will preface this by saying that my studies are mostly on Augustine poetry, which needs to conform to a strict meter and tends to include more flowery language in more complex clauses, so my perception may be skewed, but this introduction is immediately identifiable as written in modern English. When I say "direct translation," I mean from English to Latin, not the other way around: the word order is fully English, lacking any order choices made for emphasis or spatial communication. The phrasing "a humble first citizen and emperor of the world" also reads as a historical reference made by an English author: as you can read in the Latin, "first citizen" is the literal meaning of "princeps civis," the title of the emperor which is usually shortened to "princeps," as visible later in the sentence. In English, this phrasing emphasizes what Augustus's title is meant to communicate, humility, before giving him a contrasting moment of pride. In Latin, however, he just states that he is a humble emperor (written in the more formal way) and an emperor (written in the less formal way) of the world. A charitable interpretation of this would be that the repetition is being used to communicate the irony of the title: trying to appear humble while being the supreme ruler of Rome (or any other empire, I suppose). However, the fact that the wording is different for both mentions of his title makes it obvious that the connotations of this sentence were planned in English before being directly translated piece by piece. The phrasing is the way it is because "first citizen" directly translates to "princeps civis" and "emperor" directly translates to "princeps." Personally, I would have either used "princeps" twice, implying the one modified by "humilis" as meaning "citizen" and the one that is "of the world" as meaning "emperor," or used a single princeps modified by both to exemplify the irony further, putting his title in a sort of quantum state of meaning. That is, if I had to modify the existing phrase: personally, I would have given him an introduction emphasizing his authority in terms of his control over the historical narratives of Rome through his control of Rome's prominent poets, but again, my bias...
