Science and Technology

Woman learned in mathematics, astronomy, and philosophy (d. 415 ce). Daughter of the mathematician *Theon(4) of *Alexandria (1), she revised the third book of his Commentary on the Almagest. Commentaries by her on *Diophantus and *Apollonius(2) are lost. Influential in Alexandria as a teacher of Neoplatonist philosophy, she was torn to pieces by a mob of Christians at the instigation of their bishop (later Saint) Cyril (but see cyril of alexandria).

Leucippus (3), originator of the atomic theory in the second half of the 5th cent. bce. His birthplace is reported to be *Elea, *Abdera, or *Miletus (Diog. Laert. 9. 30), but all of these may be inferences from affinities between his work and that of philosophers known to come from these places; Miletus is slightly more probable than the others. He wrote later than *Parmenides, and almost certainly later than *Zeno (1) and *Melissus. *Epicurus is said to have denied his existence (Diog. Laert. 10. 13), but this is not to be taken seriously, in the face of *Aristotle's frequent mentions of him.

Of the Democritean works (see democritus) collected by Thrasyllus (Diog. Laert. 9. 45–9), two are sometimes attributed to Leucippus: The Great World System and On Mind. Both attributions appear to stem from *Theophrastus and may well be right.

Pythagoras, son of Mnesarchus, one of the most mysterious and influential figures in Greek intellectual history, was born in *Samos in the mid-6th cent. bce and migrated to *Croton in c.530 bce. There he founded the sect or society that bore his name, and that seems to have played an important role in the political life of *Magna Graecia for several generations. Pythagoras himself is said to have died as a refugee in Metapontum. Pythagorean political influence is attested well into the 4th cent., with *Archytas of Tarentum.

The name of Pythagoras is connected with two parallel traditions, one religious and one scientific. On the religious aspects, see below. Pythagoras seems to have become a legendary figure in his own lifetime and was identified by some with the *Hyperborean*Apollo. His supernatural status was confirmed by a golden thigh, the gift of bilocation, and the capacity to recall his previous incarnations. Classical authors imagine him studying in Egypt; in the later tradition he gains universal wisdom by travels in the east. Pythagoras becomes the pattern of the ‘divine man’: at once a sage, a seer, a teacher, and a benefactor of the human race.
