Although scholars continue to address old questions about Polybius, it is clear that they are also turning their attention to aspects of his history that have been inadequately dealt with in the past or have even gone largely unnoticed. Polybius' history is increasingly treated not just as a source of valuable information on the impressive expansion of Roman rule in the Mediterranean world, but also as a complex and nuanced narrative with its own interests and purposes. Moreover, since (apart from Livy's use of Polybius, which has been thoroughly discussed) most studies of Polybius' reception focus on the modern world, especially in relation to the theory of mixed constitutions, finding out more about Polybius' impact on ancient Greek and Roman authors remains a major desideratum. This volume brings together contributions which, in either posing new questions or reformulating old ones, attest both to the ardent scholarly interest currently directed toward Polybius and to the variety of hermeneutical issues raised by his work. Subjects discussed include Polybius' historical ideas, his methods of composition, his views on the role of the historian, his representation of cultural difference, his intertextual affinities, and his reception and influence. Taken together, the papers in this collection attempt to promote a deeper understanding of the qualities and peculiarities of Polybius' history, as well as to offer fresh insights into the interpretation of this important work.
