Matenadaran - The Heritage There are many manuscripts at the Matenadaran, containing the works of Aristotle(389 322 BC), Zeno, theon of alexandria (1st century AD), Secudius (2nd http://www.matenadaran.am/en/heritage/philosophy.html
Extractions: Philosophical thought has reached a high degree of development in ancient and medieval Armenia.The manuscripts of the Matenadaran include the works of more than 30 Armenian philosophers, such as Eznik Koghbatsi, Movses Kertogh (5th century), David Anhaght (5th - 6th centuries), David Harkatsi (7th century), Stepanos Sunetsi (8th century), Hovhannes Sarkavag (1045/50 - 1129), Hovhannes Yerzenkatsi, Vahram Rabuni (13th century), Hovhan Vorotnetsi (1315 - 1386), Grigor Tatevatsi (1346 - 1409), Arakel Sunetsi (1425), Stepanos Lehatsi (1699), etc. 'The Refutation of the Sects' of the 5th century famous Armenian philosopher Eznik Koghbatsi is the first original philosophical work written in Armenian after the creation of the Alphabet. Having the extention of Christianity as a purpose, he thoroughly criticises both the Armenian and the Greek paganism, the Persian zoroastrianism, the sects, etc. 'The Definition of Philosophy' written by David Anhaght (5th - 6th centuries) is the most important monument of the mundane philosophical thought in Armenia. It is one of the rare works that continues the antique philosophical traditions, widely using the theories of Platon, Aristotle, Pythagoras. At the same time many progressive theories on philosophy and logics are worked out. Many important theories were brought forward by the medieval Armenian philosophers. They regarded the primacy of sensually perceptible things and the role of the senses, the contradictions of natural phenomena, space and time, the origin and destruction of matter, etc. There are numerous interests about natural phenomena and their cognition in the works of Armenian philosophers. The 12th century scholar Hovhannes Sarkavag notes the role of experiment in the cognition of the world and advises to check the knowledge by the experiments.

Riverworld PBEM: Hypatia She learned Mathematics from her father, theon of alexandria, thelast president (possibly) of the famous Alexandrian Musuem. http://www.pennmush.org/~alansz/rw-pbem/bg/chars/hypatia.html
Extractions: She is a short (5'), slender woman of unaffected beauty. Her eyes are a warm brown, her skin is clear and sun-darkened a rich bronze. She is typically serious of mien but occassionally a lovely smile will part her full lips. ? Hypatia, was born ca. 370 AD in Alexandria, Egypt. She was killed at the hands of a Christian mob in 413 AD, having spent her life in Alexandria as a teacher of mathematics and philosophy. In addition, she was a knowledgable and prominent member of her religious community. She learned Mathematics from her father, Theon of Alexandria, the last "president" (possibly) of the famous Alexandrian Musuem. She soon surpassed him and went on to pen at least 3 texts which are known today within the fields of geometry, (?), and astronomy. She speaks Greek, Latin, Arabic (she is a mathematician, so I assume), and (possibly the language indigenous to the region, however she is of a 'privileged' and learned class so perhaps not). I also assume she can write in all of these languages. There is actually very little historical information about this amazing woman. (Not that books do not exist, but that in depth info about her life appears, from the reviews on the Web I read and the published bibliographies) and especially her mathematics is lacking.

Adventures In CyberSound: Euclid theon of alexandria (4th century AD) brought out a new revision of the work withtextual changes and some additions; his version was the basis of all published http://www.acmi.net.au/AIC/EUCLID_BIO.html
Extractions: Euclid (alt: Euklid, Eucleides) : 365 - 300 BC Euclid's The Optics is the earliest surviving work on geometrical optics, and is generally found in Greek manuscripts along with elementary works on spherical astronomy. There were a number of medieval Latin translations, which became of new importance in the fifteenth century for the theory of linear perspective. This technique is beautifully illustrated in the miniature of a street scene in this elegant manuscript from the library of the Duke of Urbino. It may once have been in the possession of Piero della Francesca, who wrote one of the principal treatises on perspective in painting.
ONE BOOK, 1393 YEARS - A History Of The Almagest Two important commentaries were by, Pappus (320) and theon of alexandria (360),these failed to improve on Ptolemys astronomy and served mainly to educate http://www.star-names.freeserve.co.uk/almagest.html
Extractions: ONE BOOK, 1393 YEARS - A history of the Almagest 1.1 Introduction One book dominated astronomy for nearly one-thousand four-hundred years. This was the Almagest of Claudius Ptolemy. Why was just one book so influential and so dominant that it took so long to be surpassed? 1.2 Ptolemy Ptolemy lived in Egypt in the period when it was part of the Roman Empire. We know very little about him personally and the dates of his life (AD.100 to 178) are only approximate. He worked in the city of Alexandria. Alexandria is located on the northern (Mediterranean) coast of Egypt. It was a city renowned for learning and had a famous library and museum. Possibly, Ptolemy himself worked in one or other of these institutions. Ptolemy wrote in Greek, which was the scientific and philosophical language of his day. He is famous for writing many books on scientific subjects. These are: "Mathematical Syntaxis" (The Almagest) Astronomy "On the Apprations of the Fixed Stars and a Collection of Prognostics" Astronomy
The Thirteenth Floor HYPATIA (370415) The daughter of theon of alexandria, was born in about 370CE. She is the earliest woman scientist whose works have been documented. http://www.sonypictures.com/movies/13thfloor/basement/data/hypatia.htm
Extractions: The daughter of Theon of Alexandria, was born in about 370 CE. She is the earliest woman scientist whose works have been documented. As a young woman, she traveled to Athens and Italy. Upon her return to Alexandria, she became a philosopher and mathematician. She was appointed to expound the doctrines of Plato and Aristotle and was a noted lecturer on the subjects of mathematics, astronomy, philosophy, and mechanics. Most of her writings dealt with mathematics, especially algebra. Her most noted work, called Arithmetica, was a commentary on the writings of Diophantus. Hypatia also wrote an explanation of the geometry works of Apollonius of Perga, which was titled, On the Conics of Apollonius. Later in her career she worked with Theon and coauthored a work on Euclid's geometry which is titled Elements. In addition to her mathematical works, Hypatia also developed an apparatus for distilling water, an instrument for measuring the level of water, a plane astrolabe (for measuring the positions of the stars, planets, and sun) and a graduated brass hydrometer for determining the specific gravity of a liquid. Hypatia's philosophical beliefs were in conflict with the views of the Christian rulers of the city of Alexandria. When Cyril, a fanatical Christian, became Partiarch of Alexadria in 412 CE he began a persecution of scholars in the city. In 415 CE Hypatia was arrested, tortured and killed in the church called Caesarium.

Extractions: This timeline is distilled down from a more general timeline originally created for Phurba. It is meant to give a better idea of the linear history of the topics discussed in Cosmologic. Some dates given are simply there to give a better grasp of the timeperiods, comparatively. This document will be expanded and fleshed out heavily in time.

Extractions: Series Editor Dwardu Cardona Volume II The history, of calendars is far from cut-and-dried. Almost every topic that this book addresses has long been the subject of heated controversy. Rose sees Hellenistic and Roman Egypt as of unparalleled importance in the history of calendar development. Even the Julian calendar had its origins in Hellenistic Egypt. Very likely, the Julian calendar itself was Sothic that is, designed to follow the movements of the star Sothis (Sirius), and not just the annual motion of the Sun. Since the traditional Egyptian calendar of 365 days fell about one-fourth of a day short of the natural year, the ancients assumed that the heliacal rising of Sirius would move through the Egyptian calendar in 365 x 4 = 1460 Julian years (that is, one Sothic peniod). Egypt's Middle Kingdom has conventionally been dated to some 4000 years ago, largely on the basis of documents indicating a heliacal rising of Sirius on Pharmuthi 16 in Year 7 of Sesostris III (in -1871, according to Parker).
Theon_of_Smyrna 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. http://homepages.compuserve.de/thweidenfeller/mathematiker/Theon_of_Smyrna.htm
Extractions: 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]:-

Extractions: English-language Abstracts of Main Articles 'An Astrologer's Map: A Relic of Late Antiquity' by Evelyn Edson and Emilie Savage-Smith A Greek map of the world, which includes a windrose, zones, places in and around Egypt, and hell, is studied in reference to its context: an anonymous astrological miscellany. Other examples of this map have been found in a second context, among anonymous scholia to Theon of Alexandria's commentary on Ptolemy's Handy Tables (Procheiroi kanones) , which were also of use to astrologers. The selection of Egyptian place-names found on the map provides some clue to its possible origin, while the omission of the Mediterranean as well as the port of Alexandria is significant. Evidence suggests that the original map (known today only through later copies) is of an earlier date than the texts surrounding it, and that it may be one of the earliest world maps preserved from Late Antiquity.

CATHOLIC ENCYCLOPEDIA: Jordanus De Nemore (Catholic Encyclopedia)Category Society Religion and Spirituality N was printed by Valderus, at Basle, in 1536, in a collection containing the cosmographicalworks of Ziegler, Proclus, Berosius, and theon of alexandria, and the http://www.newadvent.org/cathen/10740b.htm
Extractions: Home Encyclopedia Summa Fathers ... N > Jordanus (Jordanis) de Nemore A B C D ... Z The name given in MSS. of the thirteenth and fourteenth centuries to a mathematician who in the Renaissance period was called Jordanus Nemorarius. A number of his works are extant, but nothing is known of his life. It is customary to place him early in the thirteenth century. Emile Chasles, the geometrician, concluded from a study of the "Algorismus Jordani" that its author lived not later than the twelfth century. In the fourteenth century the English Dominican Nicolas Triveth, in a chronicle of his order, attributed the "De ponderibus Jordani" and the "De lineis datis Jordani" to Jordanus Saxo, who, in 1222, succeeded St. Dominic as master general of the Friars Preachers. Since then, the identity of Jordanus Saxo with Jordanus Nemorarius has been accepted by a great many authors; it seems difficult to maintain this opinion, however, as the Dominican superior general never adds de Nemore to his name, and the mathematician never calls himself Saxo. The literal translation of Jordanus de Nemore Roger Bacon quotes his "De ponderibus", as well as a commentary which had been written on it at that period. Thomas Bradwardine and the logicians who succeeded him in the school of Oxford likewise make a great deal of use of the writings of Jordanus. During the Renaissance his "De ponderibus" powerfully influenced the development of the science of statics.
Archimedes - Best Of Sicily Magazine the earth. Catoptrica dealt with, among other things, the refractionof light, and is quoted by theon of alexandria. On Sphere http://www.bestofsicily.com/mag/art77.htm
Extractions: Experimentation yielded "Archimedes' Principle" that a body immersed in fluid loses as much weight as the weight of the liquid it displaces. This is a fundamental principle of buoyancy. Using water displacement in this way, Archimedes demonstrated that Hieron's crown was not made of solid gold. Realising his discovery's validity but forgetting to dress before leaving the pool where he was experimenting, he ran down the streets of Syracuse naked shouting the now famous phrase "Eureka!" ("I've found it.") "Give me a place to stand and I'll move the Earth." Archimedes' boast became a fundamental principle of mechanics that states that a great weight can be moved by a small force using levers and other means. The water screw he devised for irrigation is still copied and used in parts of Egypt, and it was used in ancient and medieval Sicily as well.
