XII. He is also said to have been the first man who trained athletes on meat; and Eurymenes was the first man, according to the statement of Phavorinus, in the third book of his Commentaries, who ever did submit to this diet, as before that time men used to train themselves on dry figs and moist cheese, and wheaten bread; as the same Phavorinus informs us in the eighth book of his Universal History. But some authors state, that a trainer of the name of Pythagoras certainly did train his athletes on this system, but that it was not our philosopher; for that he even forbade men to kill animals at all, much less would have allowed his disciples to eat them, as having a right to live in common with mankind. And this was his pretext; but in reality he prohibited the eating of animals, because he wished to train and accustom men to simplicity of life, so that all their food should be easily procurable, as it would be, if they ate only such things as required no fire to dress them, and if they drank plain water; for from this diet they would derive health of body and acuteness of intellect. The only altar at which he worshipped was that of Apollo the Father, at Delos, which is at the back of the altar of Ceratinus, because wheat, and barley, and cheese-cakes are the only offerings laid upon it, being not dressed by fire; and no victim is ever slain there, as Aristotle tells us in his Constitution of the Delians. They say, too, that he was the first person who asserted that the soul went a necessary circle being changed about and confined at different times in different bodies. XIII. He was also the first person who introduced measures and weights among the Greeks; as Aristoxenus the musician informs us. XIV. Parmenides, too, assures us, that he was the first person who asserted the identity of Hesperus and Lucifer. XV. And he was so greatly admired, that they used to say that his friends looked on all his sayings as the oracles of God.[109] And he himself says in his writings, that he had come among men after having spent two hundred and seven years in the shades below. Therefore the Lucanians and the Peucetians, and the Messapians, and the Romans, flocked around him, coming with eagerness to hear his discourses; but until the time of Philolaus there were no doctrines of Pythagoras ever divulged; and he was the first person who published the three celebrated books which Plato wrote to have purchased for him for a hundred minæ. Nor were the number of his scholars who used to come to him by night fewer than six hundred. And if any of them had ever been permitted to see him, they wrote of it to their friends, as if they had gained some great advantage. The people of Metapontum used to call his house the temple of Ceres; and the street leading to it they called the street of the Muses, as we are told by Phavorinus in his Universal History.
