the historian. We possess a work entitled Justini Historiarum Philippicarum Libri XLIV., in the preface to which the author in forms us that his book was entirely derived from the Universal History (totius Orbis Historias), composed in Latin by TrogusPompeius. Before proceeding, therefore, to consider the former, it is necessary to inquire into the contents and character of the more important and voluminous archetype.
From the statement of Trogus Pompeius himself, as preserved by Justin (43.5), we learn that his ancestors traced their origin to the Gaulish tribe of the Vocontii, that his grandfather received the citizenship of Rome from Cn. Pompeius during the war against Sertorius, that his paternal uncle commanded a squadron of cavalry in the army of the same general in the last struggle with Mithridates, and that his father served under C. Caesar (i. e. the dictator), to whom he afterwards became private secretary. It is hence evident that the son must have flourished under Augustus; and since the recovery of the standards of Crassus from the Parthians was recorded towards the close of his history, it is probable that it may have been published not long after that event, which took place B. C. 20.
