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."

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.

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.

The medieval Catholic Church, widely considered a source of intolerance and inquisitorial fervor, was not anti-science during the Dark Ages -- in fact, the pope in the year 1000 was the leading mathematician and astronomer of his day. Called "The Scientist Pope," Gerbert of Aurillac rose from peasant beginnings to lead the church. By turns a teacher, traitor, kingmaker, and visionary, Gerbert is the first Christian known to teach math using the nine Arabic numerals and zero. In The Abacus and the Cross, Nancy Marie Brown skillfully explores the new learning Gerbert brought to Europe. A fascinating narrative of one remarkable math teacher, The Abacus and the Cross will captivate readers of history, science, and religion alike.

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.

The collection of 41 treatises in 26 Oriental manuscripts now at St John's College, Oxford, reflect the varying ways in which Europeans have sought to make themselves familiar with the cultures of the East. Acquired between the seventeenth and nineteenth centuries, most are Arabic or Persian, but there are also Syriac, Hebrew, Turkish, Ethiopic, and Gujarati items. No mere catalogue, it includes an essay by Geert Jan van Gelder, the present Laudian Professor of Arabic, University of Oxford on the Arabic poetry that owners over the years jotted down on the margins, and is lavishly illustrated with 37 examples of calligraphy, diagrams, and illuminations.The catalogue provides a detailed description of every item within each manuscript. Most of the manuscript volumes were acquired through the donation of Archbishop William Laud (d. 1645), founder of the Chair of Arabic which bears his name. Several of his volumes were acquired from the traveller and adventurer Sir Kenelm Digby (d.1665), who bought them in Amsterdam, possibly on Laud's behalf. They are an interestingly varied collection, including Qur'ans and Arabic and Persian treatises on astronomical, mathematical, and military subjects. A bi-lingual Hebrew-Latin manuscript, as well as Arabic astronomical tables, came through the donation of Edward Bernard, Savilian Professor of Astronomy from 1673 to 1691. Six more manuscripts were given to the College in the eighteenth and nineteenth centuries, including an Ottoman Turkish letter, a Gujarati merchant's map, and two Hebrew thirteenth-century deeds of conveyance collected by the antiquary John Pointer (d. 1754), one-time chaplain of Merton College, Oxford.

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.
