Extractions: [this web page last updated 31 Dec 2003] Ý The Green Lion announces a first English translation of Book IV of Conics, translated and annotated by Michael N. Fried, as a companion volume to our edition of Conics Books I-III. Conics IV deals with the way pairs of conic sections can intersect or touch each other. In his Introduction to the translation, Fried shows that this book has been misappraised by scholars too much inclined to see Apollonius's work merely as a precursor to the analytic geometry of the seventeenth century. He writes, "Playfulness is one of the real delights of Book IV. One can see in this playfulness the artful way Apollonius contends with the main challenge of the book-the problem of how the opposite sections, specifically, meet other sections of a cone and other opposite sections- how he gives this problem both foundation and context." 7 x 10", 104 pages.

Extractions: Astronomy column for 4/29/2001 Bernice's Hair The bright star Arcturus in the constellation Bootes is rising in the east right now, a sure sign that spring is finally here and that summer can't be far behind. Above Arcturus is one of the strangest sights in the sky a large fuzzy patch that resolves into a dozen or so stars for the sharp-eyed observer. The simplest pair of binoculars will reveal even more stars. The constellation associated with the fuzzy patch, called Coma Berenices, has a long and checkered history. Few fuzzy patches get their own names, let alone their own constellations. Coma Berenices, or Berenice's Hair, did, but it took a long time to get there. Also, virtually all the constellations are named after great heroes, animal and human, from ancient mythology. Coma is the only constellation named after a real, historical person. For the longest time, Berenice's Hair wasn't considered a constellation at all. The ancient Greeks hooked the fuzzy patch up with nearby Leo, the Lion, picturing it as a puff of fur at the end of the lion's tail. By 150 AD, Ptolemy, the greatest of the Greek astronomers, refers to the stars as "a nebulous mass, called the lock,", i.e., of hair. Even earlier, around 200 BCE, the Greek scientist and writer Eristosthenes identified the puff of stars as Berenice's Hair in his famous work on constellation science and mythology called The Catasterisms. Both astronomers worked in Alexandria, the great seat of ancient scholarship at the mouth of the Nile River in northern Egypt. The Berenice in question must surely be Queen Berenice II of Egypt, who lived during the third century BCE, just before Eristosthenes wrote his book. By the first century AD, the designation was set forever by the Roman poet Hyginus in his Poetic Astronomy, even though he still considered the star patch as part of Leo. It took another 1500 years for the stellar grouping to become a constellation in its own right. In 1551, the Dutch star mapper Gerardus Mercator grabbed a few nearby stars and combined them with the fuzzy patch to form the official constellation Coma Berenices. In the process, the lion finally lost its tail. The real mystery is how the stars got to be associated with the hair of an ancient Egyptian Queen in the first place. About Queen Berenice little is known. During the third century BCE, she was first the sister and then the wife of the Egyptian pharaoh Ptolemy III Euergetes. (The pharaohs often married their close relatives to keep the royal bloodline pure.) Berenice was something of a warrior and horsewoman, distinguishing herself in battle before she married Ptolemy. According to Hyginus, Ptolemy left his new wife just a few days after their nuptials to make war on Asia. Berenice vowed to the gods that she would cut off her hair if Ptolemy returned safely. This had to be considered a major sacrifice. She was apparently quite attached to her long, amber-colored tresses. At the pharaoh's safe return, the now-hairless Berenice placed her hair on the altar of the temple dedicated to her mother Arisinoe. The next day, the hair was gone. The temple priests clearly had some serious explaining to do to a very angry pharaoh and a very bald queen. Conon of Samos, an astronomer and mathematician who who worked in Alexandria, came up with the life-saving solution. He pointed to the fuzzy patch at the tail of Leo and told the royal couple that Berenice's hair had gone to join the stars. The story has the ring of truth to it. We can imagine a desperate Conon in fear of his life raising his eyes toward heaven for inspiration and finding there a glorious patch of light.

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.

Extractions: In ancient times, Samos, although small, played a really significant role in culture and politics not only for the region of Ionia, but for the entire ancient Greece. From the evidence that has been found, derives that human beings have lived on Samos since the 3rd millenium BC, if not earlier. Its favourable position at the sea crossroad that link central Greece with East played a significant role for its development. Bones from the Paleontological Museum of Mytilinion Samos Traces of the human race have been found at the Hill of Castro from the late Neolithic era (fourth millennium B.C.). The first inhabitants belong to the Pelasgic tribes that spread the worship of Hera. According to mythology, Hera was born at the banks of the rive Imvras and was considered as the protector of Samos. Thus, her sacred bird, the peacock, often appeared on currency and escutcheons of the hegemony of Samos later.

Extractions: 4 See also Berenice I , wife of an obscure Macedonian soldier, came to Egypt as a lady-in-waiting to Eurydice, bride of Ptolemy Soter , Alexander's general and founder of the Ptolemaic dynasty Before long, Berenice caught the eye of the king. Her son, Ptolemy Philadelphus , was recognized as heir in preference to Eurydice's children. Ptolemy named for her the new port he built on the Red Sea (see below). So great was her ability and her influence that King Pyrrhus of Epirus also gave the name Berenicis to a new city. Her son Philadelphus decreed divine honours to her on her death. (See Theocritus Idylls xv. and xvii.) Berenice was the daughter of Ptolemy Philadelphus , wife of the Seleucid monarch Antiochus II Theos in modern-day Syria , who, following an agreement with Ptolemy ( 249 BC ), had divorced his wife Laodice and transferred the succession to Berenice's children.

Extractions: The Ptolemaic Legacy When Ptolemy Soter assumed power, he asked Demitrius Phalerus , a follower of Aristotle , to found a library system at Alexandria that would rival that of Athens. The Alexandrian Mouseion , however, far superseded its Greek prototype to become an intellectual and scientific institution; a university system rather than a bibliotheca. It was here, in the third century BC, that Archimedes invented the pump still in use today and known as Archimedes' screw , and, in the second century BC, that Hypsicles first divided the circle of the zodiac into 360 degrees. Ancient historians claim that the library's 500,000 book collection was so comprehensive that no manuscript was available in any library worldwide that was not available in Alexandria. Have you ever heard of Euclidean Geometry? Did you know that Euclid lived, developed his theories, and wrote Elements at the Alexandria Mouseion during the reign of Ptolemy II Philadelphus? In his Elements , Euclid provided a comprehensive analysis of geometry, proportions, and theory of numbers. His other notable contribution

Extractions: 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.
