JUSTIN, a celebrated historian, lived, according to the most probable opinion, in the second century, under the reign of Antoninus Pius. He wrote, in elegant Latin, an abridgement of the history of Trogus Pompeius; comprehending the actions of almost all nations, from Ninus the founder of the Assyrian empire to the emperor Augustus. The original work, to the regret of the learned, is lost: this abridgement, being written in a polite and elegant style, was probably the reason why that age neglected the original. The best editions of Justin are, ad usum Delphini, in 4to; and cum notis variorum et Gronovii, in 8vo.
