and men came to hear his words from afar, among them Lucanians, Peucetians, Messapians and Romans. Down to the time of Philolaus it was not possible to acquire knowledge of any Pythagorean doctrine, and Philolaus alone brought out those three celebrated books which Plato sent a hundred minas to purchase. Not less than six hundred persons went to his evening lectures ; and those who were privileged to see him wrote to their friends congratulating themselves on a great piece of good fortune. Moreover, the Metapontines named his house the Temple of Demeter and his porch the Museum, so we learn from Favorinus in his Miscella/ieous History .° And the rest of the Pythagoreans used to say that not all his doctrines were for all men to hear, our authority for this being Aristoxenus in the tenth book of his Rules of Pedagogy, where we are also told that one of the school, Xenophilus by name, asked by some one how he could best educate his son, replied, " By making him the citizen of a well-governed state." Throughout Italy Pythagoras made many into good men and true, men too of note like the lawgivers Zaleucus and Charondas : for he had a great gift for friendship, and especially, when he found his own watchwords adopted by anyone, he would immediately take to that man and make a friend of him The following were his watchwords or precepts : don't stir the tire with a knife, don't step over the beam of a balance, don't sit down on your bushel, b don't eat your heart, don't help a man off with a load but help him on, always roll your bed-clothes up, don't put God's image on the circle of a ring, don't leave the pan's imprint on the ashes, don't wipe up b The x "^ was about a quart, in dry measure.
