Theon of Smyrna Born: about 70 Died: about 135 Little is known of Theon of Smyrna 's life. 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 Plato , but this is rather fanciful. As Huxley writes in [1]:-

Introduction Smyrna, in what is now W Turkey, was one of the first Christian communities in the world, and is mentioned in Revelation . See also the 2nd cent. AD mathematician Theon of Smyrna Part of the Ottoman (i.e. Turkish) Empire from c.1425, Smyrna was for centuries a prosperous trading port to rival Constantinople. The Western powers established commercial bases there (by agreement with the Ottoman Empire) as early as the 16th century (e.g. the English government-backed Levant Company estab 1581), and many western merchants lived there with their families. For centuries Smyrna was a cosmopolitan place with a large permanent European population. The westerners, from many different countries in W Europe, tended to marry among themselves, and all the families ended up related. The Maltass family went out there from England in the mid-18th cent. Late 18th cent. - early 19th cent.

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.

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.]

Zahra Ziaie Moayyed Professor E.R. Seaquist November 11, 2002 Claudius Ptolemy: Entrenching the Geocentric Concept or Abandoning the Scientific Pursuit of Knowledge? Claudius Ptolemy, the astronomer, mathematician and geographer whose geocentric system for the universe held sway for 1,500 years, serves as a reminder that intellectual capacity is no guarantee against being dead wrong. As is the case with a plethora of important ancient figures, not much is known about the life of Claudius Ptolemy. It may be rather ironic that little knowledge remains about the lives of the people who made some of the first and most significant contributions to the wealth of knowledge, but such is the tragedy of the inadequacies of historical recordings. Unfortunately, all that is known about the life of Claudius Ptolemy is that he lived from approximately 90 to 170 CE. His name is a mixture of the Roman 'Claudius' and the Greek Egyptian 'Ptolemy', which suggests that he was from a Greek family living in Egypt and a citizen of Rome. As a young boy, Claudius was taught by

Home Ancient Greek Scientists AGRICULTURALISTS ARCHITECTS ... PHYSICISTS MATHEMATICIAN, ASTRONOMER, GEOGRAPHER HIPPARCHUS OF RHODES (fl. 190 - 120 BC) Life The greatest astronomical observer of all time, and the father of astronomy, Hipparchus was born in Nicaea in Bithynia, but lived most of his life in Rhodes and Alexandria. He insisted that geography - the determination of the positions of places on earth - had to be based on the use of astronomical methods to determine their latitude and longitude: he determined latitude by application of the gnomon, the zenith of the fixed stars, the duration of the longest day of the year, and thought that longitude could be determined by observing, from each place, the moments when a solar eclipse began and ended. Work His maps were based on geometric calculation, and marked a great step forward in the history of cartography. One of the craters on the moon has been named "Hipparchus" in his honour. His work is chronicled in Stobaeus. Hipparchus invented an improved type of astrolabe, which he used to determine with accuracy the co-ordinates of the stars. He devised a globe and a planisphere. The planisphere allowed "stereographic projections" - also invented by Hipparchus - to be used to determine the precise time. He improved the dioptra, an instrument used to estimate the apparent diameter, distance and size of the sun and the moon, and used and improved various older instruments, including the plumb, the gnomon, the polos, the sundial, the clepsydra, the fixed sphere, the water clock and the rings.
