"Evans and Berggren's book is an excellent translation and welcome commentary on Geminos's texts. The translation of the Introduction to the Phenomena is a much-needed resource for the study of Hellenistic astronomy, and the introduction, commentary, and appendices the authors provide make the book a useful educational tool accessible to even the most elementary student of the history of astronomy."--Jacqueline Feke, Bryn Mawr Classical Review "On Geminos, nothing is known. But his text, now available in its entirety in English, thanks to Evans and Berggren, is a critical work for scholars of the history of astronomy and classical studies."--Choice "The Introduction is an important text that contributes greatly to our understanding of ancient astronomy... Evans and Rerggren have provided valuable discussions and illustrations of the relevant ancient instruments and tools, and the ways in which they were used in the practice of astronomy... Geminos' work is well worth reading, and classicists interested in ancient astronomy will find this book an indispensable resource."--Liba Taub, Classical World
