78 Through Gallograecia and Bithynia he marched into Asia, and examined and decided all the controversies of the provinces as he passed, and established the limits and jurisdictions of the several kings, states, and tetrarchs. Mithridates of Pergamus, who had so actively and successfully served him in Egypt, as we have related above, a man of royal descent and education (for Mithridates, king of all Asia, out of regard to his birth, had carried him along with him when very young, and kept him in his camp several years), was appointed king of Bosphorus, which had been under the command of Pharnaces. And thus he guarded the provinces of the Roman people against the attempts of barbarous and hostile kings, by the interposition of a prince firmly attached to the interests of the republic. He bestowed on him likewise the tetrarchy of Gallograecia, which was his by the law of nations and family claims, though it had been possessed for some years by Deiotarus. Thus Caesar, staying nowhere longer than the necessity of the seditions in the city required, and having settled all things relating to the provinces with the utmost success and dispatch, returned to Italy much sooner than was generally expected.
