GENIUS FEMINA. Cont'd.
Hypatia of Alexandria (A.D. 370 – 415)
A martyr to feminine intellect.
Hy
patia of Alexandria is
the earliest woman scientist whose life is well documented; she was also the
last scientist of the Golden Age of Pericles, before enlightenment gave way to
the Dark Ages. Her martyrdom has had more of an impact on the history than her
inventions, although the hydroscope itself—the first laboratory instrument to
measure the specific gravity of liquids—was a breakthrough. Born in Alexendria in A.D. 370, Hypatia came into a rarefied intellectual
world. Her father, Theon, was a mathematician and astronomer at the Museum at
Alexandria, and Hypatia was his prize pupil. She studied in Athens and Italy,
and she became a lecturer and writer in the fields of mathematics, philosophy,
astronomy and mechanics. Her classes were attended by students from throughout
the known world, and her treatise on algebra, Arithmetica, was a
thirteen-volume definitive study. Practical technology was Hypatia's main interest, which led to her invention
of the pane astrolabe, used to measure the positions of the sun and stars and to
calculate the ascendant sign of the zodiac. It consisted of a pair of rotating
discs made of open-work metal, rotating one on top of the other around a
removable peg. Hypatia perfected the device to the point where it could
accurately solve problems in spherical astronomy.
She also invented a device for measuring the level of water and another system for distillation, as well as the hydrometer. The hydrometer—or hydroscope—was a sealed tube about the size of a flute, weighted at one end. The depth to which the hydrometer sunk in a particular liquid gave a reading on the substances, specific gravity. Hypatia never married, although she was courted by and kept company with many of Alexandria's movers and shakers. Unhappily, these connections did not save her from the fanatical Christian sects whose influence was becoming increasingly felt. During her lifetime, intellectualism gave way to findamentalism, and to religious dogma. In A.D. 389 the Serapeum Library was sacked and burned by order of Theophilos, bishop of Alexandria. All neo-Platonists were persecuted, and Hypatia became a controversial figure because of her fame and influence. In A.D. 412 Cyril, the patriarch of Alexandria, vowed to rid the city of neo-Platonist "heretics." Hypatia was urged by her friends to renouce her thinking—and her teaching— but she refused. In March of A.D. 415, a group of overzealous monks took Cyril's ranting to heart and murdered Hypatia for her beliefs. Socrates Scholasticus described the scene: "They pulled her out of her chariot, they hale her to the church called Caesarium; they strip her stark naked; they raze the skin and rend the flesh of her body with sharp shells, until the breath is departed out of her body; they quarter her body, the bring her quarters unto a place called Cinaron, and burn them to ashes." It would be a thousand years until the world saw a rebirth of the pure science that Hypatia stood for...and died for.
HYPATIA, daughter of Theon the geometer and philosopher of Alexandria, was herself a well-known philosopher. She was the wife of the philosopher Isidorus, and she flourished under the Emperor Arcadius. Author of a commentary on Diophantus, she also wrote a work called The Astronomical Canon and a commentary on The Conics of Apollonius. She was torn apart by the Alexandrians and her body was mocked and scattered through the whole city. This happened because of envy and her outstanding wisdom especially regarding astronomy. Some say Cyril was responsible for this outrage; others blame the Alexandrians' innate ferocity and violent tendencies for they dealt with many of their bishops in the same manner, for example George and Proterius.
