Heaven and Earth in Ancient Greek Cosmology


Book Description

In Miletus, about 550 B.C., together with our world-picture cosmology was born. This book tells the story. In Part One the reader is introduced in the archaic world-picture of a flat earth with the cupola of the celestial vault onto which the celestial bodies are attached. One of the subjects treated in that context is the riddle of the tilted celestial axis. This part also contains an extensive chapter on archaic astronomical instruments. Part Two shows how Anaximander (610-547 B.C.) blew up this archaic world-picture and replaced it by a new one that is essentially still ours. He taught that the celestial bodies orbit at different distances and that the earth floats unsupported in space. This makes him the founding father of cosmology. Part Three discusses topics that completed the new picture described by Anaximander. Special attention is paid to the confrontation between Anaxagoras and Aristotle on the question whether the earth is flat or spherical, and on the battle between Aristotle and Heraclides Ponticus on the question whether the universe is finite or infinite.




When the Earth Was Flat


Book Description

This book is a sequel to Heaven and Earth in Ancient Greek Cosmology (Springer 2011). With the help of many pictures, the reader is introduced into the way of thinking of ancient believers in a flat earth. The first part offers new interpretations of several Presocratic cosmologists and a critical discussion of Aristotle’s proofs that the earth is spherical. The second part explains and discusses the ancient Chinese system called gai tian. The last chapter shows that, inadvertently, ancient arguments and ideas return in the curious modern flat earth cosmologies.




On the Heavens


Book Description

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).




At the Crossroads of the Earth and the Sky


Book Description

Above Misminay, the sky also is so divided by the alternation of the two axes of the Milky Way passing through the zenith. This mirror-image quadri-partition of terrestrial and celestial spheres is such that a point within one of the quarters of the earth is related to a point within the corresponding celestial quarter. The transition between the earth and the sky occurs at the horizon, where sacred mountains are related to topographic and celestial features. Based on fieldwork in Misminay, Peru, Gary Urton details a cosmology in which the Milky Way is central. This is the first study that provides a description and analysis of the astronomical and cosmological system in a contemporary community in the Americas. Separate chapters take up the sun, the moon, meteorological phenomena, the stars, and the planets. Star-to-star constellations, the "animal" dark-cloud constellations that cut through the Milky Way, and certain twilight- and midnight-zenith stars are analyzed in terms of their spatial and temporal integration within an indigenous cosmological framework. Urton breaks new ground by demonstrating the indigenous merging of such forms of "precise knowledge" as astronomy, meteorology, agriculture, and the correlation of astronomical and biological cycles within a single calendar system. More than sixty diagrams clarify this Quechua system of astronomy and relate it to more familiar principles of Western astronomy and cosmology.




Scripture and Cosmology


Book Description

Kyle Greenwood introduces readers to ancient Near Eastern cosmology and the ways in which the Bible speaks within that context. He then traces the way the Bible was read through Aristotelian and Copernican cosmologies and discusses how its ancient conceptions should be understood in light of Scripture?s authority and contemporary science.




Ptolemy's Almagest


Book Description

Ptolemy's Almagest is one of the most influential scientific works in history. A masterpiece of technical exposition, it was the basic textbook of astronomy for more than a thousand years, and still is the main source for our knowledge of ancient astronomy. This translation, based on the standard Greek text of Heiberg, makes the work accessible to English readers in an intelligible and reliable form. It contains numerous corrections derived from medieval Arabic translations and extensive footnotes that take account of the great progress in understanding the work made in this century, due to the discovery of Babylonian records and other researches. It is designed to stand by itself as an interpretation of the original, but it will also be useful as an aid to reading the Greek text.




Hellenistic Astronomy


Book Description

In Hellenistic Astronomy: The Science in Its Contexts, renowned scholars address questions about what the ancient science of the heavens was and the numerous contexts in which it was pursued.




Cosmology for the Curious


Book Description

This book is a gentle introduction for all those wishing to learn about modern views of the cosmos. Our universe originated in a great explosion – the big bang. For nearly a century cosmologists have studied the aftermath of this explosion: how the universe expanded and cooled down, and how galaxies were gradually assembled by gravity. The nature of the bang itself has come into focus only relatively recently. It is the subject of the theory of cosmic inflation, which was developed in the last few decades and has led to a radically new global view of the universe. Students and other interested readers will find here a non-technical but conceptually rigorous account of modern cosmological ideas - describing what we know, and how we know it. One of the book's central themes is the scientific quest to find answers to the ultimate cosmic questions: Is the universe finite or infinite? Has it existed forever? If not, when and how did it come into being? Will it ever end? The book is based on the undergraduate course taught by Alex Vilenkin at Tufts University. It assumes no prior knowledge of physics or mathematics beyond elementary high school math. The necessary physics background is introduced as it is required. Each chapter includes a list of questions and exercises of varying degree of difficulty.




The Cosmos in Ancient Greek Religious Experience


Book Description

Reconstructs ancient rituals in their day/night/season combining them with relevant mythology and astronomical observations to understand the ritual's cosmological links.
