David A. King (born 1941) is a British-born orientalist and specialist in the history of astronomy in the Islamic world
Biography
[edit]At an early age he decided not to follow in the footsteps of his father, Henry C. King (1915 - 2005), author of The History of the Telescope (1956) and the first director of the London Planetarium and later of the McClaughlin Planetarium in Toronto. Instead he learned Arabic and went off to the Near East and then to the U.S. to immerse himself in Medieval Islamic Studies. However, after one year of graduate school he found himself, not unwillingly, deeply entrenched in the field of the History of Astronomy, ecstatic with what he had found in the first medieval Arabic scientific manuscripts that he encountered. Thus began his journey into the then undocumented area of what he has called “astronomy in the service of Islam”.
His basic ‘education’ was at High Wycombe Royal Grammar School (1952-59), where from age 14 onward he studied only mathematics, physics and chemistry, and from age 16-18 only mathematics (he has long regarded this kind of specialisation for kids as ridiculous). Before going to university he worked as a ‘Werkstudent’ at Carl Zeiss in Oberkochen (1960). He then studied Mathematics (BA, Cambridge, 60-63), Education (Dip.Ed., Oxford, 63-64), and Near Eastern Languages and Literatures (Ph.D., Yale, 68-72). In between studying he travelled extensively in W. and E. Europe and the Near East. His first appointment was with the Sudan Government Ministry of Education (Atbara and El-Fasher, Darfur, 64-67). Thereafter he directed a project in the history of Islamic astronomy at the American Research Center in Egypt (72-79), cataloguing the 2,500 medieval Arabic scientific manuscripts in the Egyptian National Library and using Cairo as a base for research in manuscript libraries all over the world. His first university position was as Associate Professor, then Full Professor, of Near Eastern Languages and Literatures at New York University (1979-85). In 1985 he was invited to become Professor of History of Science and Director of the Institute for the History of Science, Johann Wolfgang Goethe University, Frankfurt am Main. The Institute flourished as one of the leading centres in the world for unrestricted research in the history of Islamic science but was closed when he retired in 2007.
Research on aspects of the history of Islamic science
[edit]King’s mentor in medieval Arabic and Islamic Studies at Yale University was Prof. Franz Rosenthal, who gave him photos of an Istanbul manuscript of a mathematical text by Samaw’al al-Maghribî for his first assignment. His mentor in the History of Science and his doctoral advisor was Prof. Bernard R. Goldstein, who encouraged him to investigate for his dissertation the Hâkimî Zîj of the 10th-century Egyptian astronomer Ibn Yûnus. A zîj is an astronomical handbook containing tables mainly for solar, lunar, planetary and stellar astronomy, together with explanatory text. The zîjes of al-Khwârizmî (Baghdad, ca. 830) and al-Battânî (Raqqa, ca. 910) are the best-known examples (because they became known in medieval Europe) but they are hardly the best or most interesting examples. In 1956 Prof. Edward S. Kennedy of the American University of Beirut had published a survey of some 125 zîjes, and King was able to augment this number by a few dozen during visits to libraries around the world and whilst collaborating with Prof. Kennedy in Beirut, Cairo and Frankfurt. This most fundamental research on the Islamic astronomical heritage is currently being brought to a conclusion with a grand total of some 225 zîjes from al-Andalus to India and from the Yemen to Central Asia by Dr. Benno van Dalen of the Bavarian Academy of Sciences in Munich. The number and scope and variety of these works attest to the phenomenal interest of Muslim astronomers over the centuries in the technical aspects of their subject.
King’s doctoral research uncovered a vast number of manuscripts of extensive and often highly sophisticated tables not from zîjes but for timekeeping and regulating the times of prayer for Cairo associated with Ibn Yûnus, as well as related tables for Baghdad, Damascus, Jerusalem, Tunis, Marrakesh, Taiz, Istanbul, and elsewhere. These tables were previously not known to exist. In other words, the tables which Muslims used in different locations some 50 years ago have a history going back to the ninth century, when Baghdad was the scientific centre of the world. King’s later research led to the first regional histories of astronomy in Egypt, Syria, the Yemen, and the Maghreb.
The main thrust of King’s research over close to 50 years has been the documentation, by means of hundreds of previously-unstudied Arabic manuscripts, of the ways in which astronomy – not only mathematical astronomy but also non-mathematical folk astronomy – was used over the centuries in the service of Islam: the regulation of the lunar calendar; the organisation of the five daily prayers; and the determination of the sacred direction (qibla) toward the sacred Kaaba in Mecca. These studies led to an understanding of the reasons behind the definitions of the times of the day-light prayers in terms of shadow increases over the midday minimum, as well as the reasons for the often curious orientations of medieval mosques.
King maintains that mosques were intended to face the Kaaba in Mecca and has attempted to show how they achieved this by consulting medieval astronomical and legal treatises. In 2020, he was motivated to make an extensive survey of historical mosque orientations, this to encourage colleagues in Islamic archaeology and the history of Islamic architecture to take orientations seriously.
Of course, historical mosques do not face the modern direction of Mecca; they face the directions folk thought was the direction of Mecca. This has tempted some to assert that these historical mosques face somewhere other than Mecca. Dan Gibson believes he has shown that early mosques faced Petra, and Amos Jason Deus believes that Turkish mosques were laid out in directions relating to Turkish military activities; they reached these opinions without any knowledge of the ways in which Muslims determined the “qibla” in centuries past. King’s reactions to their claims are documented in two articles “The Petra Fallacy” and “The Ottoman Mosque Fallacy”.
The first volume of his magnum opus entitled In Synchrony with the Heavens (2004) contains the first descriptions of the astronomical tables used by Muslim astronomers for timekeeping by the sun and stars and the regulation of the astronomically-defined times of Muslim prayer throughout the year for different localities. The sophistication of some of these tables and instruments is remarkable, especially those that are universal, in the sense of serving all latitudes. Also remarkable is the way in which Muslim astronomers tabulated all conceivable functions relevant to the problems of spherical astronomy. The vast majority of these tables were unknown in medieval Europe, which is one reason why they have only come to light in modern times.
Research on astronomical instruments
[edit]The second volume of King’s “In Synchrony with the Heavens” deals with the instruments that they also used: sundials, astrolabes and quadrants. Detailed descriptions of all known instruments from the Islamic East up till 1100 are presented as well as of many historically-important later ones. Most of these are beautiful objects, veritable scientific works of art. Pride of place is taken by (1) the spectacular astrolabe of the 10th-century astronomer Hâmid ibn Khidr al-Khujandî, made in Baghdad in 984; (2) the quintuply-universal astrolabe of Ibn al-Sarrâj, constructed in Aleppo in 1327 (the most sophisticated astrolabe ever made); (3) and a 14th-century astrolabe with inscriptions in Hebrew, Latin and Arabic, made in Toledo and then taken to Algiers.
King was the first to study medieval astronomical instruments, first Islamic ones, then European ones, as historical sources deserving the same respect as manuscripts. Several of the most historically important ones had been declared suspicious or fake by colleagues who did not know the language of instruments. An astrolabe signed by a late-13th-century Yemeni sultan al-Ashraf had been declared a fake because “there was no astronomy in the Yemen”. In fact, it is one of six astrolabes described by the Sultan’s teachers in a text appended to a highly sophisticated treatise on the construction and use of the astrolabe authored by the Sultan al-Ashraf himself. The oldest Latin astrolabe, from 10th-century Catalonia, desperately needed to be reinstated after it had been declared a fake by scholars versed only in the medieval textual tradition. Likewise, the sole surviving Byzantine astrolabe from 1062 has been much abused by historians who thought it displayed Islamic influence; it does not. King published lists of all known medieval instruments, Islamic and Western, arranged chronologically by region (as far as this is possible), to facilitate future research. He also was able to show that various instruments long thought to have been of medieval European inspiration, such as the universal horary quadrant with movable solar-calendrical scale and the universal horary device for timekeeping by the sun known as the navicula de Venetiis were devised in 9th-century Baghdad, as was the universal horary device for timekeeping by the stars (known only from a unique Istanbul manuscript).
A forgotten number notation from the Middle Ages
[edit]A 14th-century French astrolabe from Picardy featuring all numbers in ingenious monastic ciphers, merited a book (The Ciphers of the Monks) documenting the origins of the notation in Ancient Greek tachygraphy through Cistercian monasteries in England and what is now the border country between Belgium and France during the Middle Ages down to its afterlife in Renaissance books. The remarkable notation enables each digit from 1 to 9,999 to be represented by a unique cipher.
The most misunderstood saint in Christian history
[edit]A saint whose cult spread over a vast area of Europe, from Normandy to England to Poland and south to the Alps, was St Wilgefortis, also known as Ontcommer in the Netherlands, Kümmernis is Germany, and Uncumber in England. She is depicted as a bearded woman on a cross, and images of her survive all over Europe in museums, but also in churches. She was a saint for women in distress. She is generally believed to have resulted from a misunderstanding of the robed Christ in Lucca, but this is false because the earliest attestations of her are from 14th-century Flanders, and it was from there that her cult spread to the Netherlands, to England, to Northern France, and to all over the German-speaking world. King visited all of the sites outside Germany where she is to be found, and some inside, and consulted prayer-books from medieval Flanders. His insistence on a Flemish origin for the saint and for her cult to be influenced only later by the Luccan Christ-figure goes against the general trend to accept the latter. Her Flemish origin explains her curious name Wilgefortis, which is not derived from virgo fortis. The saint now languishes in a cloud of absurdities on the internet.
The first scientific instrument of the Renaissance, not a fake but the key to the most enigmatic painting of the Quattrocento
[edit]The beautiful little astrolabe dedicated by the young German astronomer Regiomontanus to his sponsor the Greek Cardinal Bessarion in Rome in 1462 (deemed suspicious in a report by ‘experts’ after it had been auctioned at Christie’s on the strength of an accurate expert description!) is one out of a dozen astrolabes from the same Vienna school preserved in museums around the world. An image of an angel defied identification until it was realised that Bessarion had been named after an early Egyptian saint who was venerated as an angel in the Byzantine liturgy. Furthermore, the Latin dedication is an acrostic with hidden meanings which would have amused Bessarion. However, there is more to the dedication than Regiomontanus could have possibly imagined. If one supposes that the vertical axes of the acrostic define eight spaces containing letters that identify (more than once), one can identify ‘monograms’ of individuals (like INRI for Christ and RGIO for Regiomontanus). Indeed, one can generate a program for eight persons across the board, each with dual or more identities. These are the eight persons depicted in the enigmatic ‘Flagellation of Christ’ by Piero della Francesca.
It seems that the concept of the painting and the persons depicted in it were somehow derived from the epigram. The painting is polysemous, as are the images of the eight persons in it, and this explains the difficulty it has presented to historians of art over 200 years. Some 50 different interpretations of the identities of the three moderns on the right of the painting have been shown to be appropriate, even when they are mutually inconsistent. To understand the astrolabe and its Latin inscription and the nature and significance and potential of the acrostic and the letter combinations it contains is essential before one can begin to appreciate the persons portrayed in the painting. Having deciphered these Renaissance games, we now know, for example, that the angel featured on the astrolabe, St. Bessarion, inspired the angelic figure in the painting, who represents Regiomontanus as well as three youths, recently deceased, from the Cardinal’s circle. This explains the fact that the blonde young man wears a death shroud and is barefoot, but his shroud is red because he was the protege of a cardinal. King does not expect that these revelations, documented in "Astrolabes and Angels, Epigrams and Enigmas" (2006) will be digestible for art historians. To best understand them, it is necessary to look at the dedication and the painting for a long time, or, better, to view the epigram enlarged so as to fit on top of the painting; the discoveries were made by a member of King’s instrument seminar, Bertold Holzschuh, who did precisely that.
In 2013, King was awarded the Koyré Medal of the Académie internationale d'histoire des sciences for his life's work.
