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 Astronomy and Optics from Pliny to Descartes written by Bruce Eastwood and published by Routledge. This book was released on 1989 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: A principal concern of the author in writing these articles has been to elucidate the conceptual structures that underlie the scientific thought of the Middle Ages - the philosophical and cultural assumptions, presuppositions and motivations that determine the way concepts are formed and questions are answered. In the first group of articles Professor Eastwood focuses on astronomy in Latin Europe in the 5th-11th centuries, looking especially at the use, development and interpretation of diagrams in works on planetary motion. The following studies turn to optics and visual theory. They examine Robert Grosseteste's views on the rainbow, refraction and empirical knowledge, and study specific instances of how medieval thinkers, both in the Latin and Islamic worlds, reinterpreted and reformulated the concepts they had inherited.

Available in PDF, EPUB and Kindle. Book excerpt: In On Both Sides of the Strait of Gibraltar Julio Samsó shows that astronomical sources, written in al-Andalus, the Maghrib and the Iberian Peninsula, belong to the same tradition and emphasizes the role of al-Andalus and the Iberian Peninsula in the transmission of Islamic astronomy to medieval Europe.
Download or read book Studies on the Transmission of Medieval Mathematical Astronomy written by Raymond Mercier and published by Routledge. This book was released on 2004 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies on the Transmission of Medieval Mathematical Astronomy opens with a new survey of the transmission of Hellenistic astronomy, followed by two studies on how the notion of precession was treated by Babylonian, Greek, Indian, Arabic and Latin hands. Next is a survey of the astronomical tables that appeared in Latin during the 12th century, drawn mainly from Arabic and to some extent from Hebrew, as well as a special study of the Latin tables for London and Pisa drawn originally from the 10th-century Islamic astronomer al-Sufi. For the Sanskrit texts the focus is on the demonstration that the systems were founded on observations made in India, even though much of the theory was Greek in origin. On Byzantine material there are studies of the Persian Syntaxis whose source lay in the Persian Zij-i Ilkhani, and of the diverse materials drawn on by Gemistus Plethon. Mercier's work shows that there is a unity in medieval astronomy in spite of the great diversity in cultural settings, which included South and Central Asia, the Middle East, Byzantium, and Europe. The texts were recorded in all the major languages of this great region, from Sanskrit to Latin, over a period of time stretching from the late classical world to late medieval Europe. Yet these astronomical texts have much in common, drawn from the whole apparatus of Ptolemaic, or rather more inclusively, Greek astronomy. Transmission is demonstrated partly by the continuity of technical terms, and partly by the conservation and development of numerical parameters.
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 Nicole Oresme s De visione stellarum On Seeing the Stars written by Dan Burton and published by BRILL. This book was released on 2006-11-01 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this critical edition and translation of Nicole Oresme’s On Seeing the Stars, the renowned 14th-century natural philosopher proposes that the stars are not where they seem. And perhaps nothing is where it seems. In this earliest treatise on atmospheric refraction, Oresme uses optics and infinitesimals to help solve this vexing problem of astronomy. He is the first to propose that light travels along a curve through the atmosphere – two centuries before Hooke and Newton, who are credited with the discovery. Further, he calls all sense data into doubt. Oresme’s argument concerning the curvature of light is a major milestone in the history of science, confirming that Oresme was one of the most innovative scientists of the pre-modern world.
Download or read book Optics Astronomy and Logic written by A. I. Sabra and published by Routledge. This book was released on 1994 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: These articles discuss the appropriation of Greek science by scholars in the world of medieval Islam. After presenting the historiography of this process, the volume focuses on Ibn al-Haytham, one of the most influential figures of the 11th century, and on his contribution to the science of optics and the psychology of vision. The work then analyzes how Greek thought was developed in the Islamic world, based on studies of Euclid's geomotry and critiques of Ptolemaic astronomy. Finally, some articles consider the history of logic - Aristotelian syllogism and Avicenna's views on the subject matter of logic.
Download or read book Astrolabes in Medieval Cultures written by and published by BRILL. This book was released on 2019-01-28 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published as a special issue of the journal Medieval Encounters (vol. 23, 2017), this volume, edited by Josefina Rodríguez-Arribas, Charles Burnett, Silke Ackermann, and Ryan Szpiech, brings together fifteen studies on various aspects of the astrolabe in medieval cultures. The astrolabe, developed in antiquity and elaborated throughout the Middle Ages, was used for calculation, teaching, and observation, and also served astrological and medical purposes. It was the most popular and prestigious of the mathematical instruments, and was found equally among practitioners of various sciences and arts as among princes in royal courts. By considering sources and instruments from Muslim, Christian, and Jewish contexts, this volume provides state-of-the-art research on the history and use of the astrolabe throughout the Middle Ages. Contributors are Silke Ackermann, Emilia Calvo, John Davis, Laura Fernández Fernández, Miquel Forcada, Azucena Hernández, David A. King, Taro Mimura, Günther Oestmann, Josefina Rodríguez-Arribas, Sreeramula Rajeswara Sarma, Petra G. Schmidl, Giorgio Strano, Flora Vafea, and Johannes Thomann.

Download or read book Astrolabes from Medieval Europe written by David A. King and published by Routledge. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the fourth set of studies in the Variorum series by David King, a leading authority on the history of Islamic astronomy and on medieval astronomical instruments. The first of the studies collected here deals with medieval instruments as historical sources. The following papers focus on individual astrolabes from the European Middle Ages and early Renaissance that are of singular historical importance and look at the origins of the simple universal horary quadrant and the complicated universal horary dial (navicula). The collection concludes with a list of all known medieval European astrolabes.
Download or read book Ptolemy s Science of the Stars in the Middle Ages written by Charles Burnett and published by . This book was released on 2020-09-30 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Claudius Ptolemy (c. 100-170 AD) is one of the most influential scholars of all time. While he is also the author of treatises on geography, optics and harmonics, his fame primarily stems from two works on the science of the stars, dealing with mathematical astronomy (the Almagest) and astrology (the Tetrabiblos). The Almagest and the Tetrabiblos remained the fundamental texts on the science of the stars for some 1500 years. Both were translated several times into Arabic and Latin and were heavily commented upon, glossed, discussed, and also criticised and improved upon, in the Islamic world and in Christian Europe. Yet, the reception of Ptolemy in medieval cultures is still to a large extent a terra incognita of the history of science. The Arabic and Latin versions of the Almagest and the Tetrabiblos are for the most part unavailable in modern editions, their manuscripts remain largely unexplored and, generally speaking, their history has never been systematically investigated. This volume gathers together fifteen contributions dealing with various aspects of the reception of Ptolemy's astronomy and astrology in the Islamic world and in Christian Europe up to the seventeenth century. Contributions are by Jose Bellver, Jean-Patrice Boudet, Josep Casulleras, Bojidar Dimitrov, Dirk Grupe, Paul Hullmeine, Alexander Jones, Richard L. Kremer, Y. Tzvi Langermann, H. Darrel Rutkin, Michael H. Shank, Nathan Sidoli, Carlos Steel, Johannes Thomann and Henry Zepeda.

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 Medieval Folk Astronomy and Agriculture in Arabia and the Yemen written by Daniel Martin Varisco and published by Routledge. This book was released on 1997 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: The strength of Professor Varisco's work lies in his combination of ethnographic fieldwork among highland Yemeni farmers with an extensive study of medieval Arabic manuscripts on folk astronomy and agriculture. The opening articles discuss the astronomical concept of the 'lunar stations' in pre-Islamic Arabia and as developed in Arab astronomy and almanac lore; subsequent ones expand on the significance of this for an agricultural society, and examine a unique corpus of Yemeni agricultural almanacs, dating from the Rasulid period (13th-15th centuries) to the present. A further theme is that of traditional Yemeni agriculture, with studies on irrigation practices, plough cultivation, sorghum production, and indigenous plant protection methods, as well as the use of star calendars for seasonal markers.
