"[T]his is the sort of tribute that has been long overdue to one of the ancient Greek world's most original, penetrating and ecumenically humane geniuses."--Paul Cartledge, Anglo-Hellenic Review "Roller has succeeded admirably in producing a work that will make Eratosthenes accessible to a wide variety of readers. He has made vast improvements over the previous editions of the fragments in facilitating the reading of both text and commentary... This book will be equally interesting to specialist researchers."--Courtney Roby, Hague Journal of Diplomacy "One does not have to be a trained classicist to appreciate Roller's scholarship. Indeed, the subjects he tackles are increasingly ones that resonate with the educated public as much as with specialists. Roller's new book follows this trend and will surely win new fans for its subject."--Sarah Pothecary, Strabo.ca "In addition to a careful and justified assignation of fragments to the three books of Eratosthenes' Geographika, Roller in his commentary is very alert to the extent to which Strabo misrepresents or misunderstands the purpose of Eratosthenes... The commentary is accessible and well conceived."--Hugh Lindsay, European Legacy
