Download or read book Calendars and Years written by John M. Steele and published by Oxbow Books. This book was released on 2007-10-08 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dates form the backbone of written history. But where do these dates come from? Many different calendars were used in the ancient world. Some of these calendars were based upon observations or calculations of regular astronomical phenomena, such as the first sighting of the new moon crescent that defined the beginning of the month in many calendars, while others incorporated schematic simplifications of these phenomena, such as the 360-day year used in early Mesopotamian administrative practices in order to simplify accounting procedures. Historians frequently use handbooks and tables for converting dates in ancient calendars into the familiar BC/AD calendar that we use today. But very few historians understand how these tables have come about, or what assumptions have been made in their construction. The seven papers in this volume provide an answer to the question what do we know about the operation of calendars in the ancient world, and just as importantly how do we know it? Topics covered include the ancient and modern history of the Egyptian 365-day calendar, astronomical and administrative calendars in ancient Mesopotamia, and the development of astronomical calendars in ancient Greece. This book will be of interest to ancient historians, historians of science, astronomers who use early astronomical records, and anyone with an interest in calendars and their development.

Download or read book A History of Arabic Astronomy written by George Saliba and published by NYU Press. This book was released on 1995-07-01 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: A History of Arabic Astronomy is a comprehensive survey of Arabic planetary theories from the eleventh century to the fifteenth century based on recent manuscript discoveries. George Saliba argues that the medieval period, often called a period of decline in Islamic intellectual history, was scientifically speaking, a very productive period in which astronomical theories of the highest order were produced. Based on the most recent manuscript discoveries, this book broadly surveys developments in Arabic planetary theories from the eleventh century to the fifteenth. Taken together, the primary texts and essays assembled in this book reverse traditional beliefs about the rise and fall of Arabic science, demonstrating how the traditional “age of decline” in Arabic science was indeed a “Golden Age” as far as astronomy was concerned. Some of the techniques and mathematical theorems developed during this period were identical to those which were employed by Copernicus in developing his own non-Ptolemaic astronomy. Significantly, this volume will shed much-needed light on the conditions under which such theories were developed in medieval Islam. It clearly demonstrates the distinction that was drawn between astronomical activities and astrological ones, and reveals, contrary to common perceptions about medieval Islam, the accommodation that was obviously reached between religion and astronomy, and the degree to which astronomical planetary theories were supported, and at times even financed, by the religious community itself. This in stark contrast to the systematic attacks leveled by the same religious community against astrology. To students of European intellectual history, the book reveals the technical relationship between the astronomy of the Arabs and that of Copernicus. Saliba’s definitive work will be of particular interest to historians of Arabic science as well as to historians of medieval and Renaissance European science.

Download or read book Studies in Medieval Astronomy and Optics written by J.L. Mancha and published by Taylor & Francis. This book was released on 2023-07-21 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this selection of studies, J.L. Mancha explores aspects of the development of medieval optics and astronomy, including some medieval antecedents of the work of early modern astronomers. The articles deal with Latin, Hebrew and Arabic texts, and the process of translation and transmission of knowledge, and focus on three main themes. First, the theory and astronomical use of the pinhole camera in the 12th and 13th centuries; the texts edited here contain a solution to the problem of the formation of images cast by light through triangular apertures, equivalent to Kepler's, a description of the correct procedure for measuring solar apparent diameters using finite apertures, and a derivation of the Sun's eccentricity from its apparent diameters at apogee and perigee. Second, the characteristics of the Latin and Provençal versions of Levi ben Gerson's astronomical work, composed in collaboration with the author, as well as his tables and canons for finding syzygies and the mathematical methods used in the derivation of parameters. Third, different aspects of the survival of homocentric astronomy in the Middle Ages, especially al-Bitruji's model for trepidation and the technique for calculating the hippopede resulting from Eudoxan couples.

Download or read book A Brief Introduction to Astronomy in the Middle East written by John M. Steele and published by Saqi. This book was released on 2012-03-12 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Middle East is the birthplace of astronomy and the centre for its development during the medieval period. In this brief introduction John Steele offers an intriguing insight into Middle Eastern achievements in astronomy and their profound influence on the rest of the world. Amongst other things, the book traces the Late Babylonians' ingenious schemes for modelling planetary motion. It also reveals how medieval Islamic advances in the study of the heavens, and the design of precise astronomical instruments, led to breakthroughs by Renaissance practitioners such as Copernicus and Kepler. An invaluable introduction to one of the oldest sciences in the world.

Download or read book The Light Ages The Surprising Story of Medieval Science written by Seb Falk and published by W. W. Norton & Company. This book was released on 2020-11-17 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Named a Best Book of 2020 by The Telegraph, The Times, and BBC History Magazine An illuminating guide to the scientific and technological achievements of the Middle Ages through the life of a crusading astronomer-monk. "Falk’s bubbling curiosity and strong sense of storytelling always swept me along. By the end, The Light Ages didn’t just broaden my conception of science; even as I scrolled away on my Kindle, it felt like I was sitting alongside Westwyk at St. Albans abbey, leafing through dusty manuscripts by candlelight." —Alex Orlando, Discover Soaring Gothic cathedrals, violent crusades, the Black Death: these are the dramatic forces that shaped the medieval era. But the so-called Dark Ages also gave us the first universities, eyeglasses, and mechanical clocks. As medieval thinkers sought to understand the world around them, from the passing of the seasons to the stars in the sky, they came to develop a vibrant scientific culture. In The Light Ages, Cambridge science historian Seb Falk takes us on a tour of medieval science through the eyes of one fourteenth-century monk, John of Westwyk. Born in a rural manor, educated in England’s grandest monastery, and then exiled to a clifftop priory, Westwyk was an intrepid crusader, inventor, and astrologer. From multiplying Roman numerals to navigating by the stars, curing disease, and telling time with an ancient astrolabe, we learn emerging science alongside Westwyk and travel with him through the length and breadth of England and beyond its shores. On our way, we encounter a remarkable cast of characters: the clock-building English abbot with leprosy, the French craftsman-turned-spy, and the Persian polymath who founded the world’s most advanced observatory. The Light Ages offers a gripping story of the struggles and successes of an ordinary man in a precarious world and conjures a vivid picture of medieval life as we have never seen it before. An enlightening history that argues that these times weren’t so dark after all, The Light Ages shows how medieval ideas continue to color how we see the world today.

Download or read book Essays on Medieval Computational Astronomy written by José Chabás Bergón and published by BRILL. This book was released on 2014-11-13 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the Middle Ages and early modern times tables were a most successful and economical way to present mathematical procedures and astronomical models and to facilitate computations. Before the sixteenth century astronomical models introduced by Ptolemy in Antiquity were rarely challenged, and innovation consisted in elaborating new methods for calculating planetary positions and other celestial phenomena. Essays on Medieval Computational Astronomy includes twelve articles that focus on astronomical tables, offering many examples where the meaning and purpose of such tables has been determined by careful analysis. In evaluating the work of medieval scholars we are mindful of the importance of applying criteria consistent with their own time, which may be different from those appropriate for other periods.

Download or read book Astronomies and Cultures in Early Medieval Europe written by Stephen C. McCluskey and published by Cambridge University Press. This book was released on 2000-11-20 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the astronomical practices that continued through the so-called "Dark Ages." Like the astronomies of traditional societies, early medieval astronomies established a religious framework of sacred time and ritual calender; here Christian feasts tied to a pre-Christian ritual solar calender, the date of Easter tied to the Hebrew lunar calender; and the timing of monastic prayers in terms of the course of the stars. Coupled with the remnants of ancient geometrical astronomy, these provided the framework for the rebirth of astronomy with the rise of the medieval universities.

Download or read book Reflections on Observational Astronomy in the Medieval Islamic Period written by S. Mohammad Mozaffari and published by Taylor & Francis. This book was released on 2024-12-13 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents comprehensive investigations into various facets of observational astronomy during the medieval Islamic period, spanning from the ninth to the seventeenth centuries. The chapters compiled here, originally published between 2012 and 2018, have undergone significant revisions to enhance their accuracy and explore a broad spectrum of topics organized into five main sections. Reflections on Observational Astronomy in the Medieval Islamic Period begins with solar astronomy, providing a detailed evaluation of Islamic astronomers’ determinations of fundamental solar parameters. In the realm of lunar astronomy, it examines the gradual endorsement and rationalization of annular solar eclipses, along with an exclusive historical account of predicting and observing such an event in 1283 CE. The section on planetary astronomy scrutinizes empirical discoveries that distinguish between the precession of equinoxes and the motion of apogees, as well as significant enhancements to Ptolemy’s parameters for planetary latitudes. Stellar astronomy is explored through a non-Ptolemaic star table that encompasses observations from ninth-century Baghdad to thirteenth-century Marāgha. The final section examines observational instruments, focusing on those constructed during the second period of activities at the Marāgha observatory. A critical analysis of astronomical observations conducted at the Marāgha and Istanbul observatories is a key focus of this work. This book will be invaluable to those interested in the historical progression of exact sciences; the scope, distinctive aspects, and caliber of experimental activities in medieval times; and the interplay between theory and observation throughout history. It is intended for historians, scientists (including astronomers and physicists), and particularly, historians of astronomy.

Download or read book The History of Astronomy A Very Short Introduction written by Michael Hoskin and published by OUP Oxford. This book was released on 2003-05-08 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy, perhaps the first of the sciences, was already well developed by the time of Christ. Seventeen centuries later, after Newton showed that the movements of the planets could be explained in terms of gravitation, it became the paradigm for the mathematical sciences. In the nineteenth century the analysis of star-light allowed astrophysicists to determine both the chemical composition and the radial velocities of celestial bodies, while the development of photography enabled distant objects invisible to the human eye, to be studied and measured in comfort. Technical developments during and since the Second World War have greatly enlarged the scope of the science by permitting the study of radiation. This is a fascinating introduction to the history of Western astronomy, from prehistoric times to the origins of astrophysics in the mid-nineteenth century. Historical records are first found in Babylon and Egypt, and after two millennia the arithmetical astronomy of the Babylonians merged with the Greek geometrical approach to culminate in the Almagest of Ptolemy. This legacy was transmitted to the Latin West via Islam, and led to Copernicus's claim that the Earth is in motion. In justifying this Kepler converted astronomy into a branch of dynamics, leading to Newton's universal law of gravity. The book concludes with eighteenth- and nineteenth-century applications of Newton's law, and the first explorations of the universe of stars. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly.

Download or read book Astronomy and Astrology in the Medieval Islamic World written by Edward S. Kennedy and published by Routledge. This book was released on 1998 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of studies by Edward Kennedy looks first at questions of spherical astronomy, celestial mapping and planetary models, and then deals with astrological calculations. Throughout the author emphasises the importance of advances in mathematics for understanding the development of medieval Arabic sciences. This collection of studies based on previously unexploited manuscript sources in Arabic and Persian. They were written by authors from the 9th through the 15th centuries, whose locations reached from south China in the east through Central Asia, the Middle and Near East, and North Africa, to Spain in the west. The topics are predominately astronomical rather than astrological. The former include eclipse predictions, problems in spherical astronomy, non-ptolemaic planetary theory, and the achievements of Ulugh Beg and his observatory. Astrological subjects treated are the method of calculating the ascendant, and how to determine astrological houses and lots. An astrological history of the career of Genghis Khan is also described.

Download or read book The History and Practice of Ancient Astronomy written by James Evans and published by Oxford University Press. This book was released on 1998-10-01 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Scandalous Error written by C. Philipp E. Nothaft and published by Oxford University Press. This book was released on 2018 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gregorian calendar reform of 1582, which provided the basis for the civil and Western ecclesiastical calendars still in use today, has often been seen as a triumph of early modern scientific culture or an expression of papal ambition in the wake of the Counter-Reformation. Much less attention has been paid to reform's intellectual roots in the European Middle Ages, when the reckoning of time by means of calendrical cycles was a topic of central importance to learned culture, as impressively documented by the survival of relevant texts and tables in thousands of manuscripts copied before 1500. For centuries prior to the Gregorian reform, astronomers, mathematicians, theologians, and even Church councils had been debating the necessity of improving or emending the existing ecclesiastical calendar, which throughout the Middle Ages kept losing touch with the astronomical phenomena at an alarming pace. Scandalous Error is the first comprehensive study of the medieval literature devoted to the calendar problem and its cultural and scientific contexts. It examines how the importance of ordering liturgical time by means of a calendar that comprised both solar and lunar components posed a technical-astronomical problem to medieval society and details the often sophisticated ways in which computists and churchmen reacted to this challenge. By drawing attention to the numerous connecting paths that existed between calendars and mathematical astronomy between the Fall of Rome and the end of the fifteenth century, the volume offers substantial new insights on the place of exact science in medieval culture.

Book excerpt: Edward Grant describes the extraordinary range of themes, ideas, and arguments that constituted scholastic cosmology for approximately five hundred years, from around 1200 to 1700. Primary emphasis is placed on the world as a whole, what might lie beyond it, and the celestial region, which extended from the Moon to the outermost convex surface of the cosmos.

Download or read book Stars and Numbers written by Paul Kunitzsch and published by Taylor & Francis. This book was released on 2022-04-19 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: The studies brought together in this second collection of articles by Paul Kunitzsch continue the lines of research evident in his previous volume (The Arabs and the Stars). The Arabic materials discussed stem mostly from the early period of the development of Arabic-Islamic astronomy up to about 1000AD, while the Latin materials belong to the first stage of Western contact with Arabic science at the end of the 10th century, and to the peak of Arabic-Latin translation activity in 12th century Spain. The first set of articles focuses upon Ptolemy in the Arabic-Latin tradition, followed by further ones on Arabic astronomy and its reception in the West; the final group looks at details of the transmission of Euclid's Elements.

Download or read book Astronomical Symbols on Ancient and Medieval Coins written by Marshall Faintich and published by McFarland. This book was released on 2012-04-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The coins of ancient and medieval Europe provide unique insights into the economic and political history of their period. In a time when few members of the population could read or write, the symbols depicted on coins offered a medium for communication, propaganda, and historical archiving. This work hypothesizes that astronomical symbols on ancient and medieval coins were often used as a way to record actual celestial events. The author provides more than 550 figures and line drawings of coins, maps, and astronomical events to illustrate this hypothesis. In addition, several appendices evaluate the historical accuracy of ancient and medieval coinage and offer additional examples not included in the main text.

Book excerpt: A reissue with a foreword and supplement, of a modern classic published in 1960. The invention of the mechanical clock was one of the most important turning points in the history of science and technology. This study revealed six centuries of mechanical clockwork preceding the first mechanical escapement clocks of the West of about AD 1300. Detailed and fully illustrated accounts of elaborate Chinese clocks are accompanied by a discussion of the social context of the Chinese inventions and an assessment of their possible transmission to medieval Europe. For this revised edition, Dr Joseph Needham has contributed a new foreword on recent research and perceptions. In a supplement John H. Combridge details a modern reconstruction of Su Sung's timekeeping device, which together with textual studies modifies our understanding of this important early technology.
