The theory that he was born in Halifax is now discredited because Halifax means 'holy hair', not 'holy wood'. He was educated at Oxford University . According to a seventeenth century account, he arrived at the University of Paris on June 5 , but whether as an arts student or as a licentiate (one having a Master of Arts degree from another university and thus qualified to teach) is unclear. In due course, he became a Professor of Mathematics at the University of Paris. About , his most well known work, Tractatus de Sphaera , was published. In this book, Sacrobosco discussed the

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

Books General Pages Home Index Johannes de Sacrobosco Sacrobosco (d. 1256?) is famous for his textbook De Sphaera (c. 1230) which explained the spherical geometry used by Ptolemy and his Islamic commentators and remained popular for four hundred years. It is thought he was born in England and taught at the University of Paris. Larger image (228K) Very large image (2.2M) Reliable information about the life of Johannes de Sacrobosco is scarce, and standard sources such as the Dictionary of Scientific Biography have unfortunately included as fact material deriving from the speculations and inventions of sixteenth- and seventeenth-century antiquarians. On the basis of a statement made in 1271 by his commentator Robertus Anglicus , he is believed to have been of English origin; his name is frequently anglicised as John of Holywood. At some time in the earlier part of the thirteenth century (according to a seventeenth-century account, it was June 5th 1221) he arrived in Paris and formed an association with the university there, although whether it was initially as an arts student or as a licentiate (one who, by virtue of having been made a master of arts at another university was already qualified to teach) is not clear. It is presumed that at some point he was enrolled as a regent master lecturing on mathematics and astronomy. After his death, which may have occurred in 1256, a memorial was constructed in the monastery of St. Mathurin, closely associated with the University of Paris. This was decorated with an astronomical instrument, perhaps an astrolabe, and a few lines of Latin verse which referred to Sacrobosco's
