Because the historical writings of Priscus of Panium survive only in fragments, we regrettably lack knowledge of the full complexity of this fifth century historian’s concerns. Widely cited in Byzantine sources, the greatest part of Priscus’ work is found in the Excerpta de Legationibus, which was compiled from ancient texts by the emperor Constantine VII Porphyrogenitos in the middle of the tenth century as part of an encyclopedic collation of educational and practical information. The Excerpta, which dealt with international relations, found much of interest in Priscus, whose history included a detailed account of the struggle between the Romans and Attila the Hun. Of particular value is Priscus’ first-hand account of an embassy to Attila in 449 to discuss the exchange of fugitives and other matters. On this journey Priscus served as an assistant to Maximinus, the leader of the diplomatic mission sent from Constantinople. Envoys to foreign lands regularly included in their reports detailed observations of the societies they visited, and in this tradition the fragments preserved in the Excerpta constitute an invaluable source of information about Hunnic life as well as diplomatic matters. Priscus later reworked his acute observations of the Huns made on the embassy and mixed them with other information in the larger framework of his historical treatise, adapting part of his diplomatic intelligence report to the needs of a different sort of literary enterprise. We cannot know with any certainty the thematic architectonics of this historical work, but its fragments make it clear that Priscus’ treatment of the relations between Rome and the Empire of the Huns and his development of cultural issues implicit in those relations were more subtle than the tenth century editors’ focus on diplomatics might suggest.
