Johannes de Sacrobosco Born: about 1195 in Holywood, Yorkshire, England Died: 1256 in Paris, France Show birthplace location Previous (Chronologically) Next Biographies Index Previous (Alphabetically) Next Main index John of Holywood or Johannes de Sacrobosco was educated at Oxford. 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 Ptolemy 's theory of the planets and of eclipses.

14. The Teaching Of Mathematics In Britain In The Mediaeval Ages. despite this John of Holywood, known better as johannes de sacrobosco, not onlystudied at the University in Paris but also lectured there helping to promote http://www-gap.dcs.st-and.ac.uk/~history/Education/mediaeval.html

The teaching of mathematics in Britain in the Mediaeval Ages. The decline in education in Europe and Britain especially continued through into the Mediaeval years, especially during the 11th century and the Norman conquest of England. King Harold's concerns about the English nobles' views of education and even the clergy's diminishing ability in Latin prose made little impact on the situation. Ability in warfare and defending ones land was more important at that time and the noblemen spent their time learning the skills of the fighter, rather than the scholar. Since there were few others with the time and the money to study, the level of education and mathematical knowledge of the populace dropped still further. By this time schools were reduced to little or no arithmetic, it is doubtful whether few knew more than basic counting and finger reckoning. During the 12th century the education in Scotland was beginning to improve thanks to efforts made by the Church, although the sciences were still neglected for the most part. The country was divided into 11 dioceses by the end of this century (although this number increased later) and schools attached to the new churches and cathedrals were set up much in the same manner as those south of the border. These schools aimed to teach people to read and write in order to aid their ability to understand the Scriptures. Many of these schools also started taking in the poor, rather than just the rich and those wanting to take up Orders. In Europe the situation was little better than England, although major centres of learning still existed in places like Paris where the University was founded during the 12th century, and this is where British students of ability went to study. This practise continued for many years in Scotland especially after the War of Independence with England, but English students were restricted by Henry II in 1167 when he banned them from attending the University of Paris. Cambridge and Oxford were then the only possible alternatives and these two rapidly grew into universities worthy of admiration. Despite this John of Holywood, known better as Johannes de

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

John of Holywood Johannes or Ioannes de Sacrobosco or Sacrobusco (John of Holywood) was the author of a handful of widely read medieval texts on mathematics and astronomy. Only the faintest sense of his life can be inferred; most details are speculation. Nearly all published details are, in fact, errors either invented, interpolated or propagated by commentators and authors from the Middle Ages, to eighteenth and nineteenth century antiquarians, to uncritical modern compilers. An 18th century sketch of a statue seen in Terregles church, reputed to be of John of Holywood. 'Revirosco' states that the statue was recovered from the abbey at the Reformation and taken for safekeeping to Terregles church. The statue is no longer there; it may have been removed when the oldest portion of the church was renovated for a family crypt in the late 19th century. For hundreds of years his name was a household word to any student of the liberal arts. The seven artes liberales included grammar, rhetoric and logic (the trivium ) and arithmetic, geometry, astronomy and music (the
