Jerome mentions that copies of his work on the Greek Old Testament were known in his day as "exemplaria Lucianea" but in other places he speaks rather disparagingly of the texts of Lucian. Jerome also wrote: "This (Testament) certainly differs in our language, and is led in the way of different streams; it is necessary to seek the single fountainhead. I pass over those books which are called by the name of Lucian and Hesychius, for which a few men wrongly claim authority, who anyway were not allowed to revise either in the Old Instrument after the Seventy Translators, or to pour out revisions in the New; with the Scriptures previously translated into the languages of many nations, the additions may now be shown to be false." In the absence of definite information it is impossible to decide the merits of Lucian's critical labors.
