JUSTIN (JUNIANUS JUSTINUS)  , Roman historian, probably lived during the age of the Antonines . Of his personal history nothing is known . He is the author of Historiarum Philippicarum libri XLIV., a work described by himself in his preface as a collection of the most important and interesting passages from the voluminous Historiae philippicae et tolius mundi origines et terrac situs,written in the time of Augustus by Pompeius Trogus (q.v.) . The work of Trogus is lost; but the prologi or arguments of the text are preserved by Pliny and other writers . Although the main theme of Trogus was the rise and history of the Macedonian monarchy, Justin yet permitted himself considerable freedom of digression, and thus produced a capricious anthology instead of a regular epitome of the work . As it stands, however, the history contains much valuable information . The style, though far from perfect, is clear and occasionally elegant . The book was much used in the middle ages, when the author was sometimes confounded with Justin Martyr . Ed. princeps (1470) ; J . G . Graevius (1668) ; J . F .
