"This is an absolutely wonderful book, well-written and a pleasure to read. It is generally based on the most recent research and very informative without being inaccessible to the layman. That the field of ancient astronomy is under rapid development is evident from the bibliography alone. [...] It is generously supplied with interesting and relevant illustrations and its structure and composition take the reader by the hand so that it can be read easily from cover to cover. The individual chapters can also be read on their own, and the “Historical Glossary” and indices make it an excellent handbook as well. It provides a status quaestionis in a way which is at the same time accessible to the interested layman and contains a brilliant survey and much new to be learnt for the specialist in any parts of the vast topic covered as well." - Ulla Koch, in: BMCR 2021.04.23"This is an excellent and eminently useful volume, surveying and advancing the state of the field in a very welcome, cross-cultural and interdisciplinary format. Corners of this field seem to have been developing rather quickly in the last decade or two, and scholars will be grateful to the editors and authors for the timely appearance and impressive scope of this large book." - Daryn Lehoux, in: The Classical Review 71.2 442–444
