Pompeius Trogus was a Roman historian who was likely born around 60 BCE. Given his name, it is no surprise that his grandfather fought against Q. Sertorius under Pompey the Great’s command in Spain, though his father then fought against Pompey under Julius Caesar.
Some works add the praenomen ‘Gnaeus’ to his name, though this is based on the tenuous assumption that he would have kept the same praenomen as whichever ancestor was originally a client of Pompey the Great or his father, Pompeius Strabo, both of whose praenomen was Gnaeus. The manuscripts, however, simply name him Pompeius Trogus.
While no works of Trogus directly survives, an abridgment of his Historiae Philippicae exists. The original work was a universal history in forty-four books from ancient Assyria to Augustan Rome, though the vast majority of it narrated the events surrounding Philip of Macedon and the founding the Macedonian Empire.
The abridgment was made in the second century by the historian Justin.
Trogus also reportedly wrote a natural history (sometimes called De Animalibus), from which Pliny the Elder quotes, but this has been otherwise lost.
