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
This is the first investigation of one of the main interests of astronomy in Islamic civilization, namely, timekeeping by the sun and stars and the regulation of the astronomically-defined times of Muslim prayer. The study is based on over 500 medieval astronomical manuscripts first identified by the author, now preserved in libraries all over the world and originally from the entire Islamic world from the Maghrib to Central Asia and the Yemen. The materials presented provide new insights into the early development of the prayer ritual in Islam. They also call into question the popular notion that religion could not inspire serious scientific activity. Only one of the hundreds of astronomical tables discussed here was known in medieval Europe, which is one reason why the entire corpus has remained unknown until the present. A second volume, also to be published by Brill, deals with astronomical instruments for timekeeping and other computing devices.

Book Description
This volume of 12 studies, mainly published during the past 15 years, begins with an overview of the Islamic astronomy covering not only sophisticated mathematical astronomy and instrumentation but also simple folk astronomy, and the ways in which astronomy was used in the service of religion. It continues with discussions of the importance of Islamic instruments and scientific manuscript illustrations. Three studies deal with the regional schools that developed in Islamic astronomy, in this case, Egypt and the Maghrib. Another focuses on a curious astrological table for calculating the length of life of any individual. The notion of the world centred on the sacred Kaaba in Mecca inspired both astronomers and proponents of folk astronomy to propose methods for finding the qibla, or sacred direction towards the Kaaba; their activities are surveyed here. The interaction between the mathematical and folk traditions in astronomy is then illustrated by an 11th-century text on the qibla in Transoxania. The last three studies deal with an account of the geodetic measurements sponsored by the Caliph al-Ma'mûn in the 9th century; a world-map in the tradition of the 11th-century polymath al-Bîrûnî, alas corrupted by careless copying; and a table of geographical coordinates from 15th-century Egypt.

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
The first cultural history of early modern cryptography, this collection brings together scholars in history, literature, music, the arts, mathematics, and computer science who study ciphering and deciphering from new materialist, media studies, cognitive studies, disability studies, and other theoretical perspectives. Essays analyze the material forms of ciphering as windows into the cultures of orality, manuscript, print, and publishing, revealing that early modern ciphering, and the complex history that preceded it in the medieval period, not only influenced political and military history but also played a central role in the emergence of the capitalist media state in the West, in religious reformation, and in the scientific revolution. Ciphered communication, whether in etched stone and bone, in musical notae, runic symbols, polyalphabetic substitution, algebraic equations, graphic typographies, or literary metaphors, took place in contested social spaces and offered a means of expression during times of political, economic, and personal upheaval. Ciphering shaped the early history of linguistics as a discipline, and it bridged theological and scientific rhetoric before and during the Reformation. Ciphering was an occult art, a mathematic language, and an aesthetic that influenced music, sculpture, painting, drama, poetry, and the early novel. This collection addresses gaps in cryptographic history, but more significantly, through cultural analyses of the rhetorical situations of ciphering and actual solved and unsolved medieval and early modern ciphers, it traces the influences of cryptographic writing and reading on literacy broadly defined as well as the cultures that generate, resist, and require that literacy. This volume offers a significant contribution to the history of the book, highlighting the broader cultural significance of textual materialities.

Book Description
In The Horoscope of Emperor Baldwin II Filip Van Tricht presents a microstudy of political, social and cultural life in Latin-Byzantine Constantinople and Romania. A ‘new’ set of sources is used to question the traditionally negative view of the Byzantine capital under Latin rule. Combined with an analysis of other underused historical materials, mid-13th century Latin-Byzantine Constantinople is redefined as a city that—in spite of the Western conquest during the Fourth Crusade—remained dynamic, with vibrant internal and international politics, and with interesting developments in the social, religious, artistic, and scientific spheres. Against the background of a shared Roman past the metropolis on the Bosporus became a fascinating laboratory of Latin-Byzantine interaction.

Book Description
The Poet's Ogam is a creative exploration of the Ogam, based on a 17-year study by Irish author John-Paul Patton. The text explores the historical context of Ogam and the relationship between Ogam, poetry and the Gaelic harp. It contains a range of comparative studies between Ogam and the Kabbalah, Runes, I Ching and other systems. The text also presents original creations of an Ogam calendar, a divination system, and a reconstruction of Fidchell (the ancient Irish chess game) based on Ogam. The text further includes a system of Gaelic martial arts based on an elemental Ogam framework, magical Ogam squares, Ogam pentacles and much more, that fill this Tour de Force of contemporary Ogam study and use. The Poet's Ogam carries on the Art and Science of the Filid-the Philosopher Poets who created and developed the Ogam and is a must for anyone with an interest in Celtic spirituality and magick. John-Paul Patton is generally recognised as a leading authority in Ireland of esoteric Ogam studies.

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.
