He was called 'the old Theon' by Theon of Alexandria and 'Theon the mathematician' by Ptolemy . The date of his birth is little better than a guess, but we do have some firm data about dates in his life. We know that he was making astronomical observations of Mercury and Venus between 127 and 132 since Ptolemy lists four observations which Theon made in 127, 129, 130 and 132. From these observations Theon made estimates of the greatest angular distance that Mercury and Venus can reach from the Sun. The style of his bust, dedicated by his son 'Theon the priest', gives us the date of his death to within 10 years and it is placed within the period 130-140 (hence our midpoint guess of 135). Theon's most important work is Expositio rerum mathematicarum ad legendum Platonem utilium. This work is a handbook for philosophy students to show how prime numbers , geometrical numbers such as squares, progressions, music and astronomy are interrelated. Its rather curious title means that it was intended as an introduction to a study of the works of

Theon of Smyrna (lived lived c. AD 130) Greek astronomer and mathematician. In his celestial mechanics, the planets, Sun, Moon, and the sphere of fixed stars were all set at intervals congruent with an octave. His only surviving work, Expositio rerum mathematicarum ad legendum Platoneum utilium, is in two manuscripts, one on mathematics and one on astronomy and astrology. Theon collated and organized discoveries made by his predecessors, and articulated the interrelationships between arithmetic, geometry, music, and astronomy. The section on mathematics deals with prime, geometrical, and other numbers in the Pythagorean pantheon; the section on music considers instrumental music, mathematical relations between musical intervals, and the harmony of the universe. The astronomical section is by far the most important. Theon puts forward what was then known about conjunctions, eclipses, occultations, and transits. Other subjects covered include descriptions of eccentric and epicyclic orbits, and estimates of the greatest arcs of Mercury and Venus from the Sun.

Theon of Smyrna (ca. –ca. ) was a Greek philosopher and mathematician , whose works were strongly influenced by the Pythagorean school of thought. Little is known about the early life of Theon of Smyrna; Ptolemy cites work of his on several occasions between 127 and 132, but there are few other dates that are known for certain. His death can only be dated to within ten years, based on the style of his bust created at his death; 135 is often given as a midpoint guess between the possible dates of 130 and 140 CE. Theon wrote several commentaries on the works of mathematicians and philosophers of the time; he authored three works on the philosophy of Plato , of which two are lost. The only one which survives is On Mathematics Useful for the Understanding of Plato . Theon's aim was not to create new research but rather to give a reader the necessary background to understand the writings of Plato, but the Dictionary of Scientific Biography criticizes it for failing to be useful to a student of Plato and being rather a general handbook for a student of mathematics. Other criticism of this work targets its lack of originality: it is not so much a groundbreaking work as a reference work of ideas already known at the time; however, its status as a compilation of already-established knowledge and its thorough citation of earlier sources is part of what makes it valuable.

Theon of Smyrna Theon of Smyrna, was a student of Pythagorus. His book, "Math Useful in Understanding Plato" is one of the few records we have left of the way numbers were used by the Greeks. In particular he recorded the tetractys , which represented everything representable to the Greeks. repersentable represent What was before beginning is important Theon of Smyrna (a channel ) has explained the first part of Genesis (and numbers) to me (Harold) by thinking differently (he must have used a Mac;-) and going to "before the beginning". He said it several different ways so I could understand. The beginning of perception: iaod "Before the beginning, human's existence was beyond all words Then a descriptor arose and it was god and it was a word and it was called 'the builder's word'." Or this way: "In the beginning was the info , and the info was with god, and the info was god" or this way: (he seems to be up on Marshall McLuhan ;-): "In the beginning god made the media and the media was god and the media was the message". Or "Before the beginning was 'The' or 'That' (no nouns or verbs, only

Theon ...is, of course, one of the early mathematical thinkers from Greeco-Roman times. My channel is a greater development of the Earthly Theon, called "One". One is not the original one. It is the evolved one. The original one would be back sliding as Theon believes even God learns. Mathematics was studied differently and taught differently during his life in that time. Each number being separate and individual from other numbers. One (1 One) was never added to "1" to get "2" because "1" was itself. Two One (2 One) was separately existent, as was "3". One "1" was never divided, "2" was always divided. Although he will answer to Theon, he has evolved into his beloved "1". He feels that today's math is a violation of our unity in diversity. Tones and harmonics of of the "Single Thing" are closer to his idea of fractions.

13. "One Is One For Evermore: Theon Of Smyrna" By I. M. Oderberg See p. xi, theon of smyrna Mathematics Useful for Understanding Plato One of the most interesting themes among the many in theon of smyrna is that of http://www.theosophy-nw.org/theosnw/world/med/my-imo7.htm

One Is One For Evermore By I. M. Oderberg Whenever we may think of arithmetic and other subjects dealing with figures, we tend to remember most our early struggles in school with geometry based on Euclid's Elements. But among the eminent mathematicians in Greece, the Pythagoreans took an approach very different from his. For them, mathematics had a connection with philosophy; there was a mystical tone in their work similar to that in Oriental thought. The followers of Pythagoras were indeed meticulous in their thinking with figures and their empirical work with them, but their precise mathematical speculation was not severed from the depth of metaphysical concepts. The profound difference between these two points of view may be summed up by comparing Euclid's propositions, which are logical but display no philosophical basis, with the texts of Theon of Smyrna which are in a direct line from the older Pythagoreans. The latter proceeded from principles or a priori established laws accompanied with simple demonstrations for verification and contemplation, but always using these as a means, for philosophizing about the nature of the Universe." [See p. xi, Theon of Smyrna: Mathematics Useful for Understanding Plato , by Theon of Smyrna, translated by Robert and Deborah Lawlor from the 1892 Greek/French edition of J. Dupuis (Secret Doctrine Reference Series, Wizards Bookshelf); the notes by J. Dupuis are invaluable, as also the translators' introduction and the publisher's glossary and note. The index and end-papers are of assistance, the latter showing a) a map of the ancient sites in Greece and Magna Graecia, and b) a table of five of the chief foreign alphabets.]

15. "Pythagoras' Contribution" By I. M. Oderberg (See p. xi, theon of smyrna Mathematics Useful for Understanding Plato , bytheon of smyrna, translated by Robert and Deborah Lawlor from the 1892 http://www.theosophy-nw.org/theosnw/world/med/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 . . .
