Arnaut de Zwolle, Henri
- John Koster
(b Zwolle, late 14th or early 15th century; d Paris, Sept 6, 1466). Franco-Flemish physician, astrologer, astronomer and author of a treatise on musical instruments, of which he was presumably also a maker. Even if he did not, as has been assumed, study at the University of Paris, he would have become familiar with much of its curriculum through Jean Fusoris, whom Arnaut called his master. Fusoris, who had received degrees in theology, arts and medicine at the University, was a physician, astrologer, astronomer and prolific maker of astronomical and horological devices. By 1432 Arnaut had entered the service of Philip the Good, Duke of Burgundy, as ‘professeur en medecine’, ‘astronomien’ and ‘maistre … en astrologie’. Between 1454 and 1461 he left the Burgundian court in Dijon and entered the service of the French king in Paris (Charles VII, and later Louis XI), where he died of the plague....
