Bryn Mawr Classical Review 04.06.12 Harold Tarrant, Thrasyllan Platonism. Ithaca: Cornell University Press, 1993. Pp. x + 260. ISBN 0-8014-2719-3. Reviewed by Lloyd Gerson, University of Toronto. Most classicists, including those specializing in ancient philosophy, will likely know at most two facts about Thrasyllus: he was the Emperor Tiberius' astrologer and he arranged the Platonic corpus into tetralogies. Many will assume that there is not a great deal more than this to be known about him given the extant documents. For example, John Dillon's careful and thorough survey, The Middle Platonists. 80 B.C. to A.D. 220 , devotes less than a page to Thrasyllus. It will also be assumed that this is not a particularly lamentable state of affairs, since Thrasyllus is likely to have been at best a minor figure in the history of Platonism. Harold Tarrant has set out to challenge these assumptions in his latest book, Thrasyllan Platonism. Tarrant believes that a careful study of the evidence reveals Thrasyllus to be a far more formidable figure than anyone has hitherto supposed. At the conclusion of his book he writes, "The influence of Thrasyllus, if my arguments have any credibility, would seem to have been immense. It falls into five main areas: philosophical influence upon (1) Neopythagoreanism, (2) Middle Platonism, and (3) Neoplatonic and early Christian thought; and influence upon Platonic interpretation down to our own times by means of (4) an arrangement of the Platonic corpus that survives and presents the material to us in a particular manner, giving an initial claim to authenticity to all that it contains and overwhelming suspicions of spuriousness to all that it does not contain, and (5) a text of Plato that Thrasyllus' interpretative hand has coloured (208)."

26. Pythagoras' Contribution a large part of the material in Dr. Guthrie's book and Fideler's introduction, buta good note on which to close is the excerpt from theon of smyrna, a second http://www.theosociety.org/pasadena/sunrise/37-87-8/rel-imo2.htm

Pythagoras' Contribution By I. M. Oderberg The stream of an ancient wisdom flows out of a remote antiquity. At times traces of its existence are observable while at others, when dogmatism prevails, the stream runs underground, its treasures in texts or fragments preserved in old cultures for future mankinds. In eras barren of spirituality, solitary individuals emerge out of the darkness like beacons. One whose light has endured for millennia was Pythagoras, the Greek philosopher of the sixth century BC, best known in our school days as a mathematician and formulator of the theorem of the right-angled triangle. There was, however, another side to his teachings: that involving the development and training of character. While we do not have any of his own writings, those of his immediate students and later followers testify to the quality of his life and teaching that survived his personality. Plato writes, for example, that there is no record of Homer presiding, like Pythagoras, over a band of intimate disciples who loved him for the inspiration of his society and . . . the way of life which the Pythagoreans called after their founder and which to this day distinguishes them from the rest of the world . . .

Sunrise Online A uthor Index: O - S P R S O'Day, Marilyn From Our Readers (Jun/Jul 99) Oderberg, I. M. Longtime Sunrise contributor Israel Manuel Oderberg died September 18, 2002. He was born November 30, 1912, in London, England, shortly before his family moved to Melbourne, Australia. By his midteens he had developed a serious interest in ancient Egypt and, skipping an afterschool activity to play truant at the public library, he discovered H. P. Blavatsky's Isis Unveiled . At 18 he joined the Theosophical Society, but resigned at his parents' insistence, to rejoin when he turned 21. In 1930 he entered the University of Melbourne, studying pharmacy before taking an honors course in philosophy. Employed as a pharmacist until World War II, he served in the armed forces in the signal corps. After the war he became a journalist with the Australian Jewish News , and by the early 1950s was its editor. Heavily involved in theosophical work in Australia, he visited the theosophical headquarters in 1962 and was invited to join the staff. He donated most of his large collection of books to the headquarters, and when the Theosophical Library Center opened to the public in 1972, he was appointed Research Librarian, a post he held until the mid-1990s. Manuel will be remembered not only for his encyclopedic knowledge, but for his warmth of heart, playful sense of humor, love of discussion, boundless curiosity, and youthful spirit.

28. Greek Mathematics theon of smyrna and Proclus ordered the divisions differently. Likethe Pythagoreans they placed arithmetic first, but followed http://www.perseus.tufts.edu/GreekScience/Students/Chris/GreekMath.html

Chris Weinkopf Greek Mathematics April 19, 1995 Look at the comments on this paper. Table of Contents The Divisions The Pure and the Physical Order, Purpose, and Method Greek mathematics was premised on inductive reasoning. Whereas ancient historians sough to deduce facts from observations, the mathematicians sought to explore and discover truths working from a factual foundation. Theoretical mathematics also provided ancient philosophers with the tools of logic, which were thus employed in the pursuit of practical ends. The classical interpretation of mathematics, as well as the subdivision of the discipline into specific categories, demonstrates the Greeks' approach to the subject. The Divisions A fragment of Archytus , a Pythagorean friend and contemporary of Plato, explains the Quadrivivium , the four fields into which the Pythagoreans divided mathematics: arithmetic, geometry, sphaeric (astronomy), and music. Plato classified mathematics into the same categories, but included as a separate division stereometry three-dimensional geometry between geometry and sphaeric. (The Pythagoreans considered stereometry as subfield of geometry). The ordering of the Pythagorean and Platonic classifications of mathematics was based on the physical dimensions . Arithmetic, which deals exclusively with numbers, is one-dimensional, is consequently the most simplistic of the mathematics and therefor falls first in the order. It is followed by two-dimensional geometry, then stereometry, and next astronomy, which deals with three dimensional objects in motion. Music follows astronomy because both are governed by the laws of harmony the flow of celestial bodies is harmonious to the eye as music is to the ear.

Different linear symmetry groups (frieze groups) "printed" by animals were briefly discussed by Wolf and Wolff (1956). I should recall here the Japanese director A. Kurosawa's movie Dersu Uzala . This title is the name of an old man living in the Siberian forest. He has an extraordinary ability to "read" footprints. For example, he tells the visitors that the actual footprints are belonging to an old tiger and they should be very careful because the tiger is very hungry, etc. I am sure that this ability of Dersu Uzala was a common knowledge in the hunting and gathering society.

What we know of Ptolemy's biography The most definite information that we have about Ptolemy's life comes from his own writings. His astronomical treatise, the Almagest , contains references to several dated observations that he says that he made of the several heavenly bodies at Alexandria in Egypt from the mid 120s to the early 140s A.D. The full list is as follows: 125 April 5, lunar eclipse (Ptolemy does not say who made this observation) 127 March 26, opposition of Saturn 132 February 2, Mercury at greatest elongation 130 December 15, opposition of Mars 132 September 25, autumnal equinox 133 May 6, lunar eclipse 133 May 17, opposition of Jupiter 133 June 3, opposition of Saturn 134 February 18, Venus at greatest elongation 134 June 4, Mercury at greatest elongation 134 October 3, Mercury at greatest elongation 134 October 20, lunar eclipse 135 February 21, opposition of Mars 135 April 5, Mercury at greatest elongation 135 October 1, altitude of moon 136 March 6, lunar eclipse 136 July 8, opposition of Saturn 136 August 31, opposition of Jupiter

Theon of Smyna Theon Of Smyrna The Importance Of The Quaternary Obtained By Addition Is Great In Music Because All The Harmonies Are Found In It. 2 But It Is Not Only For This Reason That All Pythagorean-Theanoians Hold It In Highest Esteem, It Is Also Because It Seems To Symbolize The Entire Nature Of The Universe. 3 It Is For This Reason That The Formula Of Their Oath Was: I Swear By The Ones Who Have Bequeathed The Tetraktys, The Source Of Eternal Nature, Into Our Souls And Unto Future Generations. 4 The Ones Who Bestowed It Were Pythagoras And Theano, And It Has Been Said The Tetraktys Appears Indeed To Have Been Discovered By Them. 5 The First Quaternary Is The One Which We Have Just Spoken: It Is Formed By Addition Of The First Four Numbers. 6 The Second Is Formed By Multiplication, Of Even And Odd Numbers, Starting From Unity. 7 Of These Numbers, Unity Is The First, Because As We Have Said, It Is The Principle Of All The Even Numbers, The Odd Numbers And Of All The Odd-Even Numbers, And Its Essence Is Simple. 8 Next Comes Three Numbers From The Odd As Well As The Even Series.

38. Tetractys Of Pythagoras According to theon of smyrna, it contains the principles of ratio, of limit andof point. The 2 and 3 on the second level are prime, incomposite numbers http://www.dontyson.150m.com/tetract.html

Free Lake Scene Screen Saver HOME RESOURCES DEMONS ... TYSON THE TETRACTYS OF PYTHAGORAS (Pythagorean tetractys of addition, as interpreted by Robert Fludd, 1626) The tetractys is a symbol composed of ten dots in an upward-pointing triangular formation. It was a sacred pattern for the school of philosophers who followed the teachings of the Greek sage Pythagoras (lived 6th century BC). They used the tetractys to swear their oaths upon, in much the same way that modern Christians swear oaths upon the Bible. The Pythagorean oath, as quoted by the Renaissance magician Cornelius Agrippa, is as follows: "I with pure mind by the number four do swear; That's holy, and the fountain of nature Eternal, parent of the mind..." Some authorities claim that the oath was sworn to the "one who bestowed the tetractys to the coming generations," which might be interpreted to mean the Monad, or the teacher Pythagoras. Probably all three God, Pythagoras, and the tetrad were in the mind of the individual taking the oath. However, I believe that the oath was primarily focused upon the tetractys itself, as the symbolic blueprint of creation. Pythagoreans possessed two tetractys, the tetractys of addition (1 + 2 + 3 + 4 = 10) and the tetractys of multiplication (1 + 2 + 3 + [2x2] + [2x2x2] + [3x3] = [3x3x3]). It is easier to understand the tetractys of multiplication by means of a simple diagram.
