This is an impressive book, which for the first time collects passages dealing with historical and historiographical methodology from across the works of Greek and Roman historiography as well as works in other genres, from Hecataeus to Ammianus Marcellinus. It is a welcome addition to a growing body of scholarship treating ancient historiography as a genre (rather than individual authors) and continues John Marincola’s excellent habit of considering this genre as a whole in the works of Greek and Roman authors writing from the 5th century BCE to the 4th century CE. All extracts have been freshly translated by Marincola and furnished with notes, which explain historical details and offer basic bibliographies. (It is a shame that these notes are found at the end of the book rather than at the bottom of each page, but that is, of course, often the case with published translations.) The extracts are preceded by an Introduction, and the extracts of each author are also furnished with brief, basic introductory information. The end-notes are followed by a short bibliography, a thematic index, an index of passages translated, and a general index.
