Much of ancient history can only be written thanks to evidence supplied by Plutarch. The historical methods and qualities of this vital source were for long subjected to little systematic analysis. However, over the last two decades an authoritative and profoundly influential set of studies has appeared in the field, the work of Christopher Pelling. Dispersed until now in a wide range of international journals and symposia, these fifteen studies are here published in a single volume, revised by the author with up-to-date annotations and bibliography. Together with three new studies, they form an essential reference-work for serious students of classical Greece and Rome.
