"The issues treated and questions posed are important, diverse and comprehensive. The contributors comprise ten experts in such different fields as literature, history, history of science, papyrology, and material culture of ancient Egypt, Mesopotamia, Greece, and Rome. (…) It presents new insights and interesting research into the perspectives on the interplay between timekeeping technologies for short time intervals and their social contexts in the old high cultures of the Babylon, Egypt, Greece and Rome. It is warmly recommended to everyone interested in ancient history and ancient astronomy or time keeping." - Lis Brack-Bernsen, University of Regensburg, in: Bryn Mawr Classical Review 2020.11.44"Down to the hour is a valuable addition to the history of astronomy, introducing and discussing evidence for time keeping in the Ancient Near East and Mediterranean. It will be useful for readers interested in an individual era and period, but even more so for those who would like to get a comparative overview of time-keeping in various parts of antiquity." - Annette Imhausen, in: Journal for the History of Astronomy 2022"The crowning achievement of this volume is that it brings together disparate examples of contexts in which short times were used in the ancient Mediterranean and Near Eastern worlds. Several themes recur across contributions: the precision of time units vs. the accuracy with which they can be measured, the utility of measuring short time, the development of technologies for measuring short time, and the accessibility of such time keeping technologies to ancient peoples."
