Pompeius Trogus, a Romanized Gaul living in the age of Augustus, wrote a forty-four book universal history (The Philippic History) of the non-Roman Mediterranean world. This work was later abbreviated by M. Junianus Justinus. Alexander the Great’s life has been examined in minute detail by scholars for many decades, but the period of chaos that ensued after his death in 323 BC has received much less attention. Few historical sources recount the history of this period consecutively. Justin’s abbreviated epitome of the lost Philippic history of Pompeius Trogus is the only relatively continuous account we have left of the events that transpired in the 40 years from 323 BC. This volume supplies a historical analysis of this unique source for the difficult period of Alexander’s Successors up to 297 BC, a full translation, and running commentary on Books 13-15.
