The statement as to the death of Pythagoras, which occurred when he was about eighty, vary. One account says that he was banished from Crotona and fled to Metapontum where he died after a self-imposed fast of forty days. Another says that he was murdered by his enemies when the temple of the school at Crotona was burned to the ground, either by the nefarious Kylon who because of his unworthiness had been refused admittance to the Brotherhood and his wicked associate Ninon, or by the frenzied townspeople. At the same time similar persecutions in the other cities where the branch schools had been established resulted in the (supposed) murder of all but a few of the younger and stronger members, who succeeded in escaping to Egypt. Thereafter individual Pythagoreans, unorganized in Schools, which were everywhere successfully suppressed, continued to keep the light burning for centuries. The doubtful point is, whether the temple and the various assembly halls of the Pythagoreans were burned at the end of the Leader's life, or about a hundred years after his banishment and death by starvation. Telauges, his "son," is said to have succeeded his father as the Head of the shattered society, but little is known of him. It is significant that the Pythagorean Brotherhood and School of the Mysteries at Crotona flourished during the last twenty-five years of the sixth century B.C., the accepted date of its overthrow being about 500 B. C. II. THE SCHOOL It was a Pythagorean maxim that "everything ought not to be told to everybody." Therefore membership in the society was secret, silent, and guarded by the most solemn forms of obligatory pledges and initiations. Members were classified as Akousmatikoi or Listeners, Probationary Members, who did not live at the School, and Mathematikoi or Students, Accepted Members, who lived with their families at the central School of the Mysteries or at one of its branches. Probably the Mathematikoi were further divided into two classes: the Pythagoristae or exoteric members, and the Pythagoreans or esoteric members. Practically any candidate of an upright and honest life was admitted at request as a Listener, but only the fit and the worthy were accepted as Students. Listeners, wishing to become Students, were forced to pass through a period of probation lasting from two to five years, during which their powers of maintaining silence were especially tested as well as their general temper, disposition, and mental capacity. A good working knowledge of arithmetic, geometry, astronomy, and music, (the four branches of Pythagorean mathematics), was required preliminary to admission to the School. Only the most approved members were admitted to the Esoteric Section. Women were admitted (an innovation from the Greek standpoint). Among these Theano was the most distinguished. She had general supervision of the women.
