Abstract

Little, if anything, in Justin scholarship has been as controversial as the dating of the so-called Epitome of the Philippic History of Pompeius Trogus. Suggested dates have varied from the time of Antoninus Pius through the third century to the end of the fourth. The latter was proposed in 1988 by Sir Ronald Syme, but has in fact received little support in subsequent literature on Justin, which has tended to accept the earlier dating . An exception is T. D. Barnes, who has voiced support for a later dating based on a linguistic parallel to Justin in the Historia Augusta. Barnes observes that Oscar Hey, author of the article ducatus in TLL , drew attention to the similarity between Justin 30.2.5 Agathocles regis lateri iunctus civitatem regebat, tribunatus et praefecturas et ducatus mulieres ordinabant and HA Heliog. 6.2 militaribus… praeposituris et legationibus et ducatibus venditis. Hey, he notes, refers at the head of that particular section of the article to Seeck's article on dux. Seeck had demonstrated—and this is now taken for granted by scholars—that from the time of Diocletian dux is used technically as a formal title, and, in drawing attention to the parallel between HA Heliog. 6.2 and Justin, Hey must have been intimating that Justin is, like the author of Heliog. 6.2, using ducatus as a formal title. He then seems to suggest that Hey was right and Justin is to be dated to at least some time after 260
