Book Description
The Adler Planetarium & Astronomy Museum in Chicago is home to one of the world's great collections of astrolabes. Roderick and Marjorie Webster, Adler Curators Emeriti, present the Western astrolabes from the Adler's collection. The earliest of these instruments dates from the 13th century, others are from the workshops of the greatest craftsmen of the Renaissance. All are described here and illustrated lavishly with photographs showing the front, the back and additional details such as the maker's signature. Introductory essays by the Websters and Sara Schechner Genuth explain the use of the astrolabe and its role in cultural and social history, while the appendices and bibliography provide information essential to the specialist.

Book Description
This is the fourth set of studies in the Variorum series by David King, a leading authority on the history of astronomy in Islamic civilization and on medieval astronomical instruments, European as well as Islamic. The first of the eleven studies collected here deals with medieval instruments in general, as precious historical sources. The following papers focus on individual astrolabes from the European Middle Ages and early Renaissance that are of singular historical importance. Two 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, ordered chronologically by region. Three "landmark" astrolabes are discussed: (1) the earliest known European astrolabe from 10th-century Catalonia, that milieu in which the astrolabe first became known to Europeans; (2) an astrolabe from 14th-century Picardy bearing numerals written in monastic ciphers as well as a later dedication mentioning two friends of Erasmus; (3) the splendid astrolabe presented in 1462 by the German astronomer Regiomontanus to his patron Cardinal Bessarion, with its enigmatic angel and Latin dedication, here presented in the context of other astrolabes of similar design from 15th-century Vienna.

Book Description
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.

Book Description
This book is about the archaeology of science, or what can be learnt from the systematic examination of the artefacts made by precision craftsmen for the study of the natural world. An international authority on historical scientific instruments, Gerard Turner has collected here his essays on European astrolabes and related topics. By 1600 the astrolabe had nearly ceased to be made and used in the West, and before that date there was little of the source material for the study of instruments that exists for more modern times. It is necessary to 'read' the instruments themselves, and astrolabes in particular are rich in all sorts of information, mathematical, astronomical, metallurgical, in addition to what they can reveal about craftsmanship, the existence of workshops, and economic and social conditions. There is a strong forensic element in instrument research, and Gerard Turner's achievements include the identification of three astrolabes made by Gerard Mercator, all of whose instruments were thought to have been destroyed. Other essays deal with the discovery of an important late 16th-century Florentine workshop, and of a group of mid-15th-century German astrolabes linked to Regiomontanus.

Book Description
This is the first comprehensive study of an ingenious number-notation from the Middle Ages that was devised by monks and mainly used in monasteries. A simple notation for representing any number up to 99 by a single cipher, somehow related to an ancient Greek shorthand, first appeared in early-13th-century England, brought from Athens by an English monk. A second, more useful version, due to Cistercian monks, is first attested in the late 13th century in what is today the border country between Belgium and France: with this any number up to 9999 can be represented by a single cipher. The ciphers were used in scriptoria - for the foliation of manuscripts, for writing year-numbers, preparing indexes and concordances, numbering sermons and the like, and outside the scriptoria - for marking the scales on an astronomical instrument, writing year-numbers in astronomical tables, and for incising volumes on wine-barrels. Related notations were used in medieval and Renaissance shorthands and coded scripts. This richly-illustrated book surveys the medieval manuscripts and Renaissance books in which the ciphers occur, and takes a close look at an intriguing astrolabe from 14th-century Picardy marked with ciphers. With Indices. "Mit Kings luzider Beschreibung und Bewertung der einzelnen Funde und ihrer Beziehungen wird zugleich die Forschungsgeschichte - die bis dato durch Widerspruechlichkeit und Diskontinuit�t gepr�gt ist - umfassend aufgearbeitet." Zeitschrift fuer Germanistik.

Book Description
The large masonry instruments designed by Sawai Jai Singh and erected in his five observatories in the early eighteenth century mark the culmination of a long process of development in astronomical instrumentation. But what kind of astronomical instruments were used in India before Jai Singh's time? Sanskrit texts on astronomy describe the construction and use of several types of instruments. Are any of these extant in museums? Such questions led me to an exploration of nearly a hundred museums and private collections in India, Europe and USA for about a quarter century. The present catalogue is the outcome of this exploration. This catalogue describes each instrument in the context of the related extant specimens, while laying special emphasis on the interplay between Sanskrit and Islamic traditions of instrumentation. Therefore, each instrument type is organized in a separate section identified by the letters of the alphabet. These sections begin with introductory essays on the history of the instrument type and its varieties, followed by a full technical description of every specimen, with art historical notes. Moreover, all engraved data are reproduced and interpreted as far as possible. In some 4300 pages, it contains 600 entries, with introductory essays and long extracts from two important Sanskrit texts, namely Mahendra Sūri's Yantrarāja and Padmanābha's Dhruvabhramādhikāra, along with English translations. Following a suggestion that a shorter version of the Catalogue, consisting of all the introductory essays and appendices, but excluding the catalogue proper, would be easier for the general reader to handle, this Abridged Version has been prepared. The pagination here remains the same as in the Catalogue. Those who wish to read about individual instruments can always consult the Catalogue.
