Ancient Astronomers

The History and Practice of Ancient Astronomy combines new scholarship with hands-on science to bring readers into direct contact with the work of ancient astronomers. While tracing ideas from ancient Babylon to sixteenth-century Europe, the book places its greatest emphasis on the Greek period, when astronomers developed the geometric and philosophical ideas that have determined the subsequent character of Western astronomy. The author approaches this history through the concrete details of ancient astronomical practice. Carefully organized and generously illustrated, the book can teach readers how to do real astronomy using the methods of ancient astronomers. For example, readers will learn to predict the next retrograde motion of Jupiter using either the arithmetical methods of the Babylonians or the geometric methods of Ptolemy. They will learn how to use an astrolabe and how to design sundials using Greek and Roman techniques. The book also contains supplementary exercises and patterns for making some working astronomical instruments, including an astrolabe and an equatorium. More than a presentation of astronomical methods, the book provides a critical look at the evidence used to reconstruct ancient astronomy. It includes extensive excerpts from ancient texts, meticulous documentation, and lively discussions of the role of astronomy in the various cultures. Accessible to a wide audience, this book will appeal to anyone interested in how our understanding of our place in the universe has changed and developed, from ancient times through the Renaissance.

Ireland is home to some of the world's oldest astronomically-aligned structures, giant stone monuments erected over 5,000 years ago. Despite their apparent simplicity, these megalithic edifices were crafted by a scientifically knowledgeable community of farmers who endeavoured to enshrine their beliefs in a stellar afterlife within the very fabric of their cleverly-designed stone temples.Finally back in print, this reissued edition presents evidence suggesting the builders of monuments such as Newgrange and its Boyne Valley counterparts were adept astronomers, cunning engineers and capable surveyors. Their huge monuments are memorials in stone and earth, commemorating their creators' perceived unity with the cosmos and enshrining a belief system which resulted from a crossover between science and spirituality.As investigation of this awe-inspiring civilisation of people continues on many levels, evidence is emerging that significant archaeological sites dating from deep in prehistory are linked - not just through mythology, archaeology and cosmology - but through an arrangement of complex, and in some cases astonishing, alignments. Some of these alignments of ancient sites stretch from one side of Ireland to another.While the accounts of the lives of some prominent Irish saints appear to be steeped in folklore and mystery, it seems from new interpretations of the literature that the cosmic world view which existed in Neolithic Ireland experienced a continuity right into the Early Christian period.Join us on this fascinating exploration of stones, stars and stories."The sheer amount of information contained within the book is mind-boggling. It is well thought out and structured . . . The more you read the evidence the more convinced you become."- Astronomy & Space magazine"Refreshing and fascinating . . . a wonderful magical book, sumptuously illustrated and a must for anyone who loves to delve deep into our past." - Kenny's Irish Bookshop"A fascinating insight into Ireland's ancient burial sites" - Irish Independent"A monument" - Drogheda Independent"It is a beautiful book and very well written. The information that you collected is outstanding." - Barbara Carter, co-author, The Myth of the Year and The Goddess and the Bull"The authors . . . reach interesting and challenging conclusions about the significance of ancient astronomical knowledge. The book is jammed with colour illustrations, maps and photographs. A thoroughly interesting read!" - Archaeology Ireland."An essential book that demonstrates just how much the beliefs and practicesof our ancestors were influenced by the movement of the stars, in particularthose of the constellation Cygnus - the celestial swan and Northern Cross -once seen as a source of life and the destination of the soul in death. Amust have tome for all those passionate about what remains of our fastdisappearing ritual monuments of the prehistoric age." - Andrew Collins, author of The Cygnus Mystery

A leading astronomer takes readers behind the scenes of the thrilling science of stellar archaeology Astronomers study the oldest observable stars in the universe in much the same way archaeologists study ancient artifacts on Earth. Anna Frebel takes readers into the far-flung depths of space and time to provide a gripping firsthand account of the cutting-edge science of stellar archaeology. Weaving the latest findings in astronomy with her own compelling insights as one of the world's leading researchers in the field, she explains how sections of the night sky are "excavated" in the hunt for these extremely rare, 13-billion-year-old relic stars and how this astonishing quest is revealing tantalizing new details about the origins and evolution of the cosmos. Along the way, Frebel recounts her own stories of discovery, offering an insider's perspective on this exciting frontier of science.

Long before astronomy was a science, humans used the stars to mark time, navigate, organize planting and dramatize myths. This encyclopaedia draws on archaeological evidence and oral traditions to reveal how prehistoric humans perceived the skies and celestial phenomena.

An authoritative introduction to the fascinating topic of archaeoastronomy—ancient peoples' understanding and use of the skies. Ancient Astronomy: An Encyclopedia of Cosmologies and Myth draws on archaeological evidence and oral traditions to reveal how prehistoric humans perceived the skies and celestial phenomena. With over 200 entries, it offers a number of ways to approach ancient astronomy, from key examples and case studies worldwide (Stonehenge; Mexican and Egyptian pyramids; Chaco Canyon, New Mexico; the Nazca lines in Peru) to general themes (cosmologies, calendars, ancient ideas of space and time, origin myths), to fundamental concepts and methods (how the sky has changed over the centuries, how to survey a site), and to the field's most frequently asked questions (How did ancient peoples navigate the ocean using the stars? How does astrology relate to ancient astronomy? Can ancient sites be dated astronomically?) By revealing the astronomical significance of some of the world's most famous ancient landmarks and enduring myths and by showing how different themes and concepts are connected, Ancient Astronomy: An Encyclopedia of Cosmologies and Myth brings a unique authoritative perspective to an area too often left to speculation and sensationalism.

On the Heavens (Greek: Περὶ οὐρανοῦ, Latin: De Caelo or De Caelo et Mundo) is Aristotle’s chief cosmological treatise: written in 350 BC it contains his astronomical theory and his ideas on the concrete workings of the terrestrial world. It should not be confused with the spurious work On the Universe (De mundo, also known as On the Cosmos).

A pioneer in the fields of astrophysics and astro-archeology, J. Norman Lockyer believed that ancient Egyptian monuments were constructed "in strict relation to the stars." In this celebrated study, he explores the relationship between astronomy and architecture in the age of the pharaohs. Lockyer addresses one of the many points already extensively investigated by Egyptologists: the chronology of the kings of Egypt. All experts are in accord regarding the identity of the first monarch, but they cannot agree upon the dates of his reign within a thousand years. The author contends that by applying a knowledge of astronomy to the actual site orientation of the region's pyramids and temples, accurate dating can be achieved. In order to accomplish this, Lockyer had to determine the level of the ancient Egyptian ideas of astronomy. Some of his inferences have been invalidated by subsequent scholarship, but many of his other conclusions stand firm and continue to provide sensational leads into contemporary understanding of archaic astronomy.

Astronomical and astrological knowledge circulated in many ways in the ancient world: in the form of written texts and through oral communication; by the conscious assimilation of sought-after knowledge and the unconscious absorption of ideas to which scholars were exposed. The Circulation of Astronomical Knowledge in the Ancient World explores the ways in which astronomical knowledge circulated between different communities of scholars over time and space, and what was done with that knowledge when it was received. Examples are discussed from Mesopotamia, Egypt, the Greco-Roman world, India, and China.
