The Pythagoreans were bound together in a brotherhood, the members of which had rules that are not now understood, but which linked them so as to form a sort of club, with common religious observances and pursuits of science, especially mathematics and music. And they were taught to restrain their passions, especially that of anger, and to endure with patience all kinds of suffering; believing that such self-restraint brought them nearer to the gods, and that death would set them free from the prison of the body. The souls of evil-doers would, they thought, pass into the lower and more degraded animals, while those of good men would be gradually purified, and rise to a higher existence. This, though lamentably deficient, and false in some points, was a real religion, inasmuch as it gave a rule of life, with a motive for striving for wisdom and virtue. Two friends of this Pythagorean sect lived at Syracuse, in the end of the fourth century before the Christian era. Syracuse was a great Greek city, built in Sicily, and full of all kinds of Greek art and learning; but it was a place of danger in their time, for it had fallen under the tyranny of a man of strange and capricious temper, though of great abilities, namely Dionysius. He is said to have been originally only a clerk in a public office, but his talents raised him to continually higher situations, and at length, in a great war with the Carthaginians, who had many settlements in Sicily, he became general of the army, and then found it easy to establish his power over the city. This power was not according to the laws, for Syracuse, like most other cities, ought to have been governed by a council of magistrates; but Dionysius was an exceedingly able man, and made the city much more rich and powerful, he defeated the Carthaginians, and rendered Syracuse by far the chief city in the island, and he contrived to make everyone so much afraid of him that no one durst attempt to overthrow his power. He was a good scholar, and very fond of philosophy and poetry, and he delighted to have learned men around him, and he had naturally a generous spirit; but the sense that he was in a position that did not belong to him, and that everyone hated him for assuming it, made him very harsh and suspicious. It is of him that the story is told, that he had a chamber hollowed in the rock near his state prison, and constructed with galleries to conduct sounds like an ear, so that he might overhear the conversation of his captives; and of him, too, is told that famous anecdote which has become a proverb, that on hearing a friend, named Damocles, express a wish to be in his situation for a single day, he took him at his word, and Damocles found himself at a banquet with everything that could delight his senses, delicious food, costly wine, flowers, perfumes, music; but with a sword with the point almost touching his head, and hanging by a single horsehair! This was to show the condition in which a usurper lived!
