Statement of academic interests:

Over the past 30 years I have contributed substantially to the documen­tation of the history of science in medieval Islamic civilization, unearthing countless sources that were previously unknown, and publishing analyses and overviews thereof. In particular, I have provided the first documentation of what I call “Astronomy in the service of Islam”. This refers to the ways in which Muslims over the centuries determined the sacred direction towards the sacred Kaaba in Mecca and regulated their times of prayer, defined in terms of the position of the sun relative to the local horizon, within a calendar regulated by the moon. My research was not restricted to technical scientific texts, but also included texts relating to simple folk science and the sacred law. In this way, I have also documented Muslim concerns in folk astronomy and the notion of a sacred folk geography with the world centred on the Kaaba. This research led to the first understanding of the often surprising orientations of medieval mosques.

I have also been the first to use medieval Islamic and European scientific instruments as historical sources. Examples are the documentation of the development of highly sophisticated Islamic maps preserving direction and distance to Mecca at the centre; the history of a forgotten medieval European number notation used mainly in monasteries and also attested on a 14th-century astrolabe from Picardy; and a detailed investigation of an astrolabe with inscriptions in Hebrew, Latin and Arabic.

My interests in medieval Christianity have resulted in the first serious account in English of a much-misunderstood medieval virgin saint. Most recently I have worked on the complex relationship between a Latin epi­gram on an astrolabe by Regiomontanus, the leading astronomer of the 15th century, and the enigmatic “Flagellation of Christ” by Piero della Francesca, the leading mathematician-artist of that century.

(The first volume deals with astronomical timekeeping by the sun and stars and the regulation of the astronomically-defined times of Muslim prayer for over a millennium. It is based on over 500 Arabic manuscripts unearthed by the author in libraries around the world that had never been studied before. The earliest sources are from 8th- and 9th-century Baghdad, the later ones from all over the Islamic world. The second volume deals with the astronomical instruments used by Muslim astronomers for over a millennium, most of which have not been published previously. It includes the first detailed descriptions of all of the instruments from 8th-, 9th and 10th-century Baghdad, and much new information based on several hundred instruments preserved in museums and private collections around the world.

  • Astrolabes and Angels, Epigrams and Enigmas – From Regio­montanus’ Acrostic for Cardinal Bessarion to Piero della Francesca’s Flagellation of Christ, (Boethius – Texte und Abhandlungen zur Geschichte der Mathematik und der Naturwissenschaften, Menso Folkerts, ed., Band 56, Stuttgart: Franz Steiner, 2007, xi+348 pp. (A detailed study of a Latin epigram with two levels of hidden messages. The first – an acrostic with eight vertical axes – was specifically intended by Regiomontanus to give pleasure to his new patron, Cardinal Bessarion. The second – found in eight spaces across the epigram – was probably derived by the two men together: it provides the scenario for a very remarkable painting. Eight persons and one classical god – whose double or multiple identities are suggested by the letters of the epigram – feature in the enigmatic Flagellation of Christ by Piero della Francesca, a mathematician-artist well known to Bessarion. Some 40-odd identifications of the three men on the right of this painting have been suggested over the past 150 years, none based on any kind of documentary evidence. This new interpretation of the painting confirms several of these earlier proposals, even in cases where their identifications were mutually exclusive. For more information see here.)
