Book Description
These tables for A.D. 2 to A.D. 1649 are an extension, with some improvements, of earlier ones for 601 B.C. to A.D. 1. As before, they give the geocentric positions (tropic celestial longitudes & latitudes, i.e. with respect to the mean equinox of date), in units of 0 degrees.01 for the Sun & planets, & 0 degrees.1 for the Moon, at 16h Universal Time - 4 P.M. Greenwich Civil Time - 7 P.M. local mean time of 45 degrees East longitude (Babylon), on the indicated dates, all in the Julian calendar, hence for Julian dates 5n + 1/6 for the Moon, Mercury, & Venus, & 1-n + 1/6 for the Sun, Mars, Jupiter, & Saturn. The same adaptation of the theories of Leverrier, Gaillot, & Hansen, with modified elements by Schoch, was used as before, except as noted below. The chief change has been to improve the positions of Jupiter & Saturn. Tables.

Book Description
Skywatchers of Ancient Mexico helped establish the field of archaeoastronomy, and it remains the standard introduction to this subject. Combining basic astronomy with archaeological and ethnological data, it presented a readable and entertaining synthesis of all that was known of ancient astronomy in the western hemisphere as of 1980. In this revised edition, Anthony Aveni draws on his own and others' discoveries of the past twenty years to bring the Skywatchers story up to the present. He offers new data and interpretations in many areas, including: The study of Mesoamerican time and calendrical systems and their unprecedented continuity in contemporary Mesoamerican culture The connections between Precolumbian religion, astrology, and scientific, quantitative astronomy The relationship between Highland Mexico and the world of the Maya and the state of Pan-American scientific practices The use of personal computer software for computing astronomical data With this updated information, Skywatchers will serve a new generation of general and scholarly readers and will be useful in courses on archaeoastronomy, astronomy, history of astronomy, history of science, anthropology, archaeology, and world religions.

Book Description
This is the first English-language monograph on Marcus Manilius, a Roman poet of the first century AD, whose Astronomica is our earliest extant comprehensive treatment of astrology. Katharina Volk brings Manilius and his world alive for modern readers by exploring the manifold intellectual traditions that have gone into shaping the Astronomica: ancient astronomy and cosmology, the history and practice of astrology, the historical and political situation at the poem's composition, the poetic and generic conventions that inform it, and the philosophical underpinnings of Manilius' world-view. What emerges is a panoroma of the cultural imagination of the Early Empire, a fascinating picture of the ways in which educated Greeks and Romans were accustomed to think and speak about the cosmos and man's place in it.

Book Description
Presents 200 hitherto unpub. astronomical texts & horoscopes written in Greek on papyrus, which were excavated a century ago in the rubbish heaps of Oxyrhynchus, a district capital of Roman Egypt. Through these documents we obtain the first coherent picture of the range of astronomical activity, chiefly in the service of astrology, during the Roman Empire. The astronomy of this period turns out to have been much more varied than we previously thought, with Babylonian arithmetical methods of prediction coexisting with tables based on geometrical models of orbits. Editions of the texts are accomp. by facing translations & explanatory & philological commentaries. The intro. provides the first comprehensive treatment of astronomical papyri, explaining their contents & purpose, the underlying astronomical theories, & strategies for analyzing & dating them. Tables & graphs.
