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

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.

Chronology Based on statistical, census and antiquarian accounts Neolithic - Earthwork causeways (cursus), burials and, later, at least one stone circle (later dubbed ' The Twelve Apostles ') built through the parish. The area was a religious/ceremonial/occupation centre of some significance. 6th century AD - Irish preacher Congal (?) said to have settled in the oaken wood (Dair Congal in gaelic is 'the oak of Congal'). Said to have died in 602. 'Reviresco', 'Holywood: A Forgotten Dumfriesshire Abbey', Gallavidian Annual (1922), pp. 4-40. Late 12th century - 'Reviresco' suggests that John, Lord of Kirkconnell of the Maxwell family was responsible for the establishment of Holywood Abbey c1121. Later historians put the foundation closer to 1180. The abbey was founded by the Premonstratensian Order, which followed the rule of St. Augustine. Six other monasteries of this Order were founded in Scotland, including Saulseat, Whithorn and Tongland in Galloway. The Abbey was documented by the names Dercongal, Drumcongal, Dercongall (Celtic); Sacro Bosco, Sacri Nemoris, Sancti Nemoris Halywood (Latin); St.Bois, Saint Boyse, Seint Boyse, Le Wod (French); Haliwood, Halywood, Holtwood, Holywood and Holy Wood (Anglo-Saxon).

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.

Paradigm , No. 16 (May, 1995) John Denniss Chessins, Chignal Smealey, Chelmsford, Essex CM1 4TN In this article two particular features of the presentation of multiplication tables (or, more accurately, the multiplication table, as it was always referred to) in textbooks are considered namely, the range of numbers to be included in the table and the organisation of the results on the page. The texts in question are all in English and cover the period from around 1300 (when what is thought to be the earliest arithmetical manuscript in English was written) to 1900, after which separate textbooks tended to be written for the Primary and Secondary schools, the latter not usually including tables at all and the former often giving results in partial form at different stages. (However, there was, and still is, considerable variation.) In all some 45 texts are considered. Dates in the body of this text refer to year of original publication. commutative principle (e.g. 3 x 4 = 4 x 3) and thus require children to learn nearly twice as many results as they need.

Brief History of Origami European Classic Origami Origami is not "Japanese" art. We can recognize a picture in the 1490 edition of "Tractatus de Sphaera Mundi," which was written by Johannes de Sacrobosco (John of Holywood) in 13th century and printed over 60 times through the middle of 17th century, to be the same as that of Boat in "Ramma Zushiki." If it is really an origami boat, it is unlikely to have descended from Japan, since Japanese origami at that time would be ceremonial one if any. John Webster referred to a "paper prison" in his play "The Duchess of Malfi," which was premiered around 1614 and published in 1623. It is probably an origami model known as Water Bomb today. It does not appear in any Japanese sources of Edo era. We can find some unequivocal references to the origami of 19th century all across Europe. In addition, German National Museum has origami horses and riders, which are thought to have been folded around 1820. In the middle of 19th century, Friedrich Fröbel established the world first kindergarten. His educational system included some toys called "Gifts" and some plays called "Occupations." One of the occupations was undoubtedly origami. Only a few models of 19th century European origami can be found in contemporary Japanese sources. Even now, very few Japanese know Pajarita (Little Bird,) though every Spanish knows it. On the other hand, Orizuru was not known in Europe at that time though it was typical of Japanese classic origami.
