What did the Romans know about their world? Quite a lot, as Daryn Lehoux makes clear in this fascinating and much-needed contribution to the history and philosophy of ancient science. Lehoux contends that even though many of the Romans' views about the natural world have no place in modern science-that umbrella-footed monsters and dog-headed people roamed the earth and that the stars foretold human destinies - their claims turn out not to be so radically different from our own. Lehoux explores a wide range of sources from what is unquestionably the most prolific period of ancient science, from the highly technical works by Galen and Ptolemy to the more philosophically oriented physics and cosmologies of Cicero, Lucretius, Plutarch, and Seneca. Examining the tools and methods that the Romans employed for their investigations of nature, as well as their cultural, intellectual, political, and religious contexts, Lehoux demonstrates that the Romans had sophisticated and novel approaches to nature, approaches that were empirically rigorous, philosophically rich, and epistemologically complex.

The Greeks and Romans lived according to a distinctively Hellenic conception of time as an aspect of cosmic order and regularity. Appropriating ideas from Egypt and the Near East, the Greeks integrated them into a cosmological framework governed by mathematics and linking the cycles of the heavenly bodies to the human environment. From their cosmology they derived instruments for measuring and tracking the passage of time that were sophisticated embodiments of scientific reasoning and technical craft, meant not solely for the study of specialists and connoisseurs but for the public gaze. Time and Cosmos in Greco-Roman Antiquity, the accompanying catalogue for the exhibition at the Institute for the Study of the Ancient World, New York University, explores through thematic essays and beautiful illustrations the practical as well as the artistic, ideological, and spiritual role of time technology and time imagery in the Mediterranean civilizations. Highlights among the more than one hundred objects from the exhibition include marvelously inventive sundials and portable timekeeping devices, stone and ceramic calendars, zodiac boards for displaying horoscopes, and mosaics, sculptures, and coins that reflect ancient perceptions of the controlling power of time and the heavens. Contributors include James Evans, Dorian Gieseler Greenbaum, Stephan Heilen, Alexander Jones, Daryn Lehoux, Karlheinz Schaldach, John Steele, and Bernhard Weisser.

The focus of this book is the interplay between ancient astronomy, meteorology, physics and calendrics. It looks at a set of popular instruments and texts (parapegmata) used in antiquity for astronomical weather prediction and the regulation of day-to-day life. Farmers, doctors, sailors and others needed to know when the heavens were conducive to various activities, and they developed a set of fairly sophisticated tools and texts for tracking temporal, astronomical and weather cycles. Sources are presented in full, with an accompanying translation. A comprehensive analysis explores questions such as: What methodologies were used in developing the science of astrometeorology? What kinds of instruments were employed and how did these change over time? How was the material collected and passed on? How did practices and theories differ in the different cultural contexts of Egypt, Mesopotamia, Greece and Rome?

For the first time the sources are presented in full, with an accompanying translation.
