Branch of Science Scholars Nationality English John of Holywood (ca. 1200) Also called John of Sacrobosco. Twelfth Century English translator who put together a book on spherical trigonometry called The Sphere from what he was able to understand of the ancient Greeks' work. The Sphere became the standard textbook in astronomy until the mid-fifteenth century. Like Gerard , the translator of the Almagest, John did not have the mathematical sophistication to comprehend any but the most basic concepts.

He became a canon of the Order of St Augustine at the monastery of Holywood in Nithsdale. In 1220 Sacrobosco went to study in Paris. Although almost all dates for Sacrobosco are guesses we do know one date precisely for, on 5 June 1221, he was appointed a teacher at the University of Paris. Soon after this he became professor of mathematics at Paris. Sacrobosco promoted Arabic methods of arithmetic and algebra in his teachings. In De Algorismo he discusses calculating with positive integers. The work contains 11 chapters, one each on topics such as addition, subtraction, multiplication, division, square roots and cube roots. In 1220 Sacrobosco wrote Tractatus de Sphaera a book on astronomy in four chapters. The first chapter deals with the shape and place of the Earth within a spherical universe. The second chapter deals with various circles on the shy. The third chapter describes rising and setting of heavenly bodies from different geographical locations while the fourth chapter gives a brief introduction to

Sacrobosco's De sphaera mundi (editio princeps 1472) was the first printed astronomical book, and a fundamental text of medieval and post-medieval astronomy. It is a synthesis of Ptolemy and his Arabic commentators, presenting an elegant, accessible Ptolemaic cosmology, and for this reason was adopted as the most authoritative astronomical textbook of its time. From the time of its composition, ca 1220, Sacrobosco's De sphaera 'enjoyed great renown, and from the middle of the thirteenth century it was taught in all the schools of Europe. In the sixteenth century it gained the attention of mathematicians, including Clavius. As late as the seventeenth century it was used as a basic astronomy text... ' (John F. Daly in DSB). It was the most frequently printed astronomical work, some 30 incunable editions alone being published, and an even greater number of sixteenth-century editions.
