This chapter presents new, annotated translations of the geographical testimonia and fragments of Eudoxos of Knidos (391/0–338/7 BC), arranged as 79 extracts. The chapter introduction identifies Eudoxos’ multiple areas of expertise and suggests that his original contribution lay particularly in the area of Earth measurement, including what may have been a novel concept of a central parallel of latitude for the inhabited portion of the globe. He did not follow Hekataios’ clockwise organization of material, and knew more about the eastern Mediterranean and adjacent lands than about other regions. Like Hekataios, however, he shows a lively interest in many aspects of human societies and history; he was perhaps aware of Airs, Waters, and Places (Chapter 5 of this volume). His text survived down to Byzantine times and was highly influential.
