Book Description
Instruments for solving astronomical problems are part of a continuous tradition reaching far back through the Middle Ages into the Hellenistic world. Dr. Kennedy expands the history of analog computers by providing an account of an important development in Central Asia where, in the Samarqand observatory of the Timurid prince Ulugh Beg, an outstanding mathematician of the fifteenth century invented his unique planetary equatorium. With this mechanico-graphical device, Kashi determined solar, lunar, and planetary true longitudes and predicted eclipses, obtaining magnitude, time, and duration. His was the only equatorium with which the determination of planetary latitudes was attempted. In this sense it represents the apex of development reached by this class of instrument. Dr. Kennedy here presents the text of the Persian manuscript describing Kashi's instrument together with an English translation and commentaryÃ? Originally published in 1960. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
Contemporary technical architectural drawings, in establishing a direct relationship between the drawing and its object, tend to privilege the visible physical world at the expense of the invisible intangible ideas and concepts, including that of the designer’s imagination. As a result, drawing may become a utilitarian tool for documentation, devoid of any meaningful value in terms of a kind of knowledge that could potentially link the visible and invisible. This book argues that design drawings should be recognized as intermediaries, mediating between the world of ideas and the world of things, spanning the intangible and tangible. The notion of the 'Imaginal' as an intermediary between the invisible and visible is discussed, showing how architectural drawings lend themselves to this notion by performing as creative agents contributing not only to the physical world but also penetrating the realm of concepts. The book argues that this 'in-between' quality to architectural drawing is essential and that it is critical to perceive drawings as subtle bodies that hold physical attributes (for example, form, proportion, color), highly evocative, yet with no matter. Focusing on Islamic geometric architectural drawings, both historical and contemporary, it draws on key philosophical and conceptual notions of imagination from the Islamic tradition as these relate to the creative act. In doing so, this book not only makes important insights into the design process and act of architectural representation, but more broadly it adds to debates on philosophies of the imagination, linking both Western and Islamic traditions.

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
Photographs of selected Islamicate globes from the thirteenth to the nineteenth centuries, as well as line drawings based on written descriptions, accompany the historical an analytical discussion. The fourth chapter on iconography analyses the constellation figures on the Smithsosonian globe from the perspective of an art historian. This chapter was contributed by Andrea P.A. Belloli. The second major part of the study presents a discussion of the star names engraved on the Mughal globe, tracing the origins of the term sin Greek mythology or early Bedouin constellation outlines. The discussion of each constellation is accompanied by a photograph of the constellation as depicted on the Smithsonian globe. An account of lunar mansions is included as background to early Bedouin asterisms, which greatly affected later Islamicate star names and eventually "modern" western star names.
