Conon of Samos Born: about 280 BC in Samos Died: about 220 BC in (possibly) Alexandria, Egypt Show birthplace location Previous (Chronologically) Next Biographies Index Previous (Alphabetically) Next Main index Version for printing Conon of Samos is said to have served as court astronomer to Ptolemy III (also known as Ptolemy Euergetes) in Alexandria, see for example [1] and [2]. However, Neugebauer [5] claims that:- It is only a modern invention to make Conon a 'court astronomer'; no such rank existed in Ptolemaic Egypt... Conon is remembered particularly for Callimachus's poem Berenice's Lock about the constellation Coma Berenices. It may be as a result of this poem that Conon is well known to Virgil and Propertius The story of the constellation Coma Berenices is that Queen Berenice II, the wife of Ptolemy Euergetes, swore a vow that she would dedicate a lock of her hair to the temple if her husband returned victorious from the Third Syrian War. The war was fought by Ptolemy Euergetes to avenge the murder of his sister in Syria. When he returned victorious in 245 BC, Berenice cut off the lock of her hair and placed it in the temple. The following day the lock of hair had vanished and Conon declared that he could see it in the stars between Virgo, Leo and Bootes. From that time on the constellation has been known as Coma Berenices. Conon was a lifelong friend of Archimedes and the two exchanged mathematical ideas.

Home Ancient Greek Scientists AGRICULTURALISTS ARCHITECTS ... PHYSICISTS GEOGRAPHER CONON OF SAMOS (fl. 3rd century BC) Life Conon lived mostly in Alexandria, where he was court astronomer to Ptolemy III Euergetes. He succeeded Euclid at the Alexandrian School. Although he is chiefly known as an astronomer and astro-meteorologist, he also worked on many mathematical problems with Archimedes, who had been a student of his. He is cited by Apollonius of Perga and Pappus. He discovered the Spiral of Archimedes, a curve that was used extensively by Archimedes in some of his mathematical investigations. Conon discovered the constellation which he called Coma Berenices ("Berenice's Hair"), thus immortalising Ptolemy's wife, Queen Berenice, and her luxuriant tresses. Callimachus wrote a poem under this title, which was translated into Latin by Catullus. Work Conon's principal writings are: "On astronomy": 7 books. Dedicated to Ptolemy III Euergetes. Contained among other matters some of his own observations on eclipses. Hipparchus based his work on these books. Lost. "Parapegma": Calendar of meteorological forecasts and of the risings and settings of the stars. Based on observations made in Italy and Sicily at the time of Ptolemy. (It was then that he made the acquaintance of Archimedes.) Lost.

18. Archimedes the form of correspondence with the principal mathematicians of his time,including the Alexandrian scholars conon of samos and Eratosthenes of Cyrene. http://www.crystalinks.com/archimedes.html

Archimedes Archimedes was a famous mathematician whose theorems and philosophies became world known. He gained a reputation in his own time which few other mathematicians of this period achieved. He is considered by most historians of mathematics as one of the greatest mathematicians of all time. He discovered pi. Most of the facts about his life come from a biography about the Roman soldier Marcellus written by the Roman biographer Plutarch. According to Plutarch, Archimedes had so low an opinion of the kind of practical invention at which he excelled and to which he owed his contemporary fame that he left no written work on such subjects. While it is true thatapart from a dubious reference to a treatise, On Sphere-Making - all of his known works were of a theoretical character, nevertheless his interest in mechanics deeply influenced his mathematical thinking. Not only did he write works on theoretical mechanics and hydrostatics, but his treatise Method Concerning Mechanical Theorems shows that he used mechanical reasoning as a heuristic device for the discovery of new mathematical theorems. He was best known for his discovery of the relation between the surface and volume of a sphere and its circumscribing cylinder, for hisformulation of a hydrostatic principle Archimedes' principle and for inventing the Archimedes screw (a device for raising water).

In Bradbury's "Fahrenheit 451" the job of firemen is to burn books. Some men and women memorize the content of important books ( like in Homer's time) hoping that in the future the state will again allow these books to be printed. The Bibliotheke or Library of Alexandria Michael Lahanas Die Bibliothek von Alexandrien ...I have always imagined that Paradise will be a kind of library. Jorge Luis Borges Poema de los Dones, from El Hacedor Archaeologists have found what they believe to be the site of the Library of Alexandria, often described as the world's first major seat of learning. A Polish-Egyptian team has excavated parts of the Bruchion region of the Mediterranean city and discovered what look like lecture halls or auditoria. Two thousand years ago, the library housed works by the greatest thinkers and writers of the ancient world. Many works were later destroyed in a fire. For example from the 90 plays of Aeschylus we know only 7 in complete form. Announcing their discovery at a conference being held at the University of California, Zahi Hawass, president of Egypt's Supreme Council of Antiquities, said that the 13 lecture halls uncovered could house as many as 5,000 students in total. A conspicuous feature of the rooms, he said, was a central elevated podium for the lecturer to stand on. See: BBC News BIBLIOTHEKE biblioqhkh , or apoqhkh bibliwn ), primarily, the place where a collection of books was kept; secondarily, the collection itself (Festus, s.v.). Little as the states of antiquity dealt with the instruction of the people, public collections of books appear to have been very ancient. That of Peisistratus was intended for public use (Gell.vii.17;Athen. i. p3); it was subsequently removed to Persia by Xerxes. About the same time
