    Having now completed our account of the philosophy of Ionia starting with Thales, as well as of its chief representatives, let us proceed to examine the philosophy of Italy, which was started by Pythagoras,[*](Compare Clement Alex. Strom. i. 62 Πυθαγόρας μὲν οὖν Μνησάρχου Σάμιος, ὥς φησιν Ἱππόβοτος, ὡς δὲ Ἀριστόξενος ἐν τῷ Πυθαγόρου βίῳ, καὶ Ἀρίσταρχος καὶ Θεόπομπος, Τυρρηνὸς ἦν, ὡς δὲ Νεάνθης, Σύριος ἢ Τύριος, ὥστε εἷναι κατὰ τοὺς πλείστους τὸν Πυθαγόραν βάρβαρον τὸ γένος. Porphyry also (V. Pyth. i.) favours the connexion with Phoenicia, so that the boy Pythagoras was instructed there by Chaldaeans before, on his return to Samos, he enjoyed the instruction of Pherecydes of Syros and of Hermodainas of Samos.) son of the gem-engraver Mnesarchus, and according to Hermippus, a Samian, or, according to Aristoxenus, a Tyrrhenian from one of those islands which the Athenians held after clearing them of their Tyrrhenian inhabitants. Some indeed say that he was descended through Euthyphro, Hippasus and Marmacus from Cleonymus, who was exiled from Phlius, and that, as Marmacus lived in Samos, so Pythagoras was called a Samian.

    From Samos he went, it is said, to Lesbos with an introduction to Pherecydes from his uncle Zoïlus. He had three silver flagons made and took them as presents to each of the priests of Egypt. He had brothers, of whom Eunomus was the elder and Tyrrhenus the second; he also had a slave, Zamolxis, who is worshipped, so says Herodotus,[*](iv. 93 sq.) by the Getans,

    V2_323
    as Cronos. He was a pupil, as already stated, of Pherecydes of Syros, after whose death he went to Samos to be the pupil of Hermodamas, Creophylus’s descendant, a man already advanced in years. While still young, so eager was he for knowledge, he left his own country and had himself initiated into all the mysteries and rites not only of Greece but also of foreign countries.

    Now he was in Egypt when Polycrates sent him a letter of introduction to Amasis; he learnt the Egyptian language, so we learn from Antiphon in his book On Men of Outstanding Merit, and he also journeyed among the Chaldaeans and Magi. Then while in Crete he went down into the cave of Ida with Epimenides; he also entered the Egyptian sanctuaries,[*](Compare Clement Alex. Strom. i. 66 Θαλῆς . . . τοῖς Αἱγυπτίων προφήταις συμβεβληκέναι εἴρηται, καθάπερ καὶ ὁ Πυθαγόρας αὐτοῖς γε τούτοις διʼ οὓς καὶ περιετέμνετο, ἵνα δὴ καὶ εἰς τὰ ἄδυτα κατελθὼν τὴν μνστικὴν παρὰ Αλγυπτίων ἐκμάθοι φιλοσοφίαν. Cf. also Iamblichus, Vit. Pyth. 18 sq.) and was told their secret lore concerning the gods. After that he returned to Samos to find his country under the tyranny of Polycrates; so he sailed away to Croton in Italy, and there he laid down a constitution for the Italian Greeks, and he and his followers were held in great estimation; for, being nearly three hundred in number, so well did they govern the state that its constitution was in effect a true aristocracy (government by the best).

    This is what Heraclides of Pontus tells us he used to say about himself: that he had once been Aethalides and was accounted to be Hermes’ son, and Hermes told him he might choose any gift he liked except immortality; so he asked to retain through life and through death a memory of his experiences. Hence in life he could recall everything, and when he died he still kept the

    V2_325
    same memories. Afterwards in course of time his soul entered into Euphorbus and he was wounded by Menelaus. Now Euphorbus used to say that he had once been Aethalides and obtained this gift from Hermes, and then he told of the wanderings of his soul, how it migrated hither and thither, into how many plants and animals it had come, and all that it underwent in Hades, and all that the other souls there have to endure.

    When Euphorbus died, his soul passed into Hermotimus, and he also, wishing to authenticate the story, went up to the temple of Apollo at Branchidae, where he identified the shield which Menelaus, on his voyage home from Troy, had dedicated to Apollo, so he said: the shield being now so rotten through and through that the ivory facing only was left. When Hermotimus died, he became Pyrrhus, a fisherman of Delos, and again he remembered everything, how he was first Aethalides, then Euphorbus, then Hermotimus, and then Pyrrhus. But when Pyrrhus died, he became Pythagoras, and still remembered all the facts mentioned.

    There are some who insist, absurdly enough, that Pythagoras left no writings whatever. At all events Heraclitus, the physicist,[*](Fr. 129 D., 17 B.) almost shouts in our ear, Pythagoras, son of Mnesarchus, practised inquiry beyond all other men, and in this selection of his writings made himself a wisdom of his own, showing much learning but poor workmanship. The occasion of this remark was the opening words of Pythagoras’s treatise On Nature, namely, Nay, I swear by the air I breathe, I swear by the water I drink, I will never suffer censure on account of this

    V2_327
    work. Pythagoras in fact wrote three books. On Education, On Statesmanship, and On Nature.

    But the book which passes as the work of Pythagoras is by Lysis of Tarentum, a Pythagorean, who fled to Thebes and taught Epaminondas.[*](§§ 6-7 ἔνιοι μὲν καθηγησαμένου. Hesychius in Suidas (s.v.), an authority older than Schol. Plat. 600 B, proves that this passage is a coherent whole. The fragment of Heraclitus (B 129 Diels, 17 Byw.) is certainly genuine. There may be, in ἱστορίην, an allusion to the study of mensuration in Egypt. The pretended explanation, he spoke thus because . . . introduces an extract from a work which, like all those attributed to Pythagoras, must have been a late forgery.) Heraclides, the son of Serapion, in his Epitome of Sotion, says that he also wrote a poem On the Universe, and secondly the Sacred Poem which begins:

      Young men, come reverence in quietude
    1. All these my words;
    thirdly On the Soul, fourthly Of Piety, fifthly Helothales the Father of Epicharmus of Cos, sixthly Croton, and other works as well. The same authority says that the poem On the Mysteries was written by Hippasus to defame Pythagoras, and that many others written by Aston of Croton were ascribed to Pythagoras.

    Aristoxenus says that Pythagoras got most of his moral doctrines from the Delphic priestess Themistoclea. According to Ion of Chios in his Triagmi he ascribed some poems of his own making to Orpheus.[*](F.H.G. Fr. 12, ii. p. 49. The same fragment is found in Clem. Alex. Strom. i. 131 Ἴων δὲ ὁ Χῖος ἐν τοῖς Τριαγμοῖς καὶ Πυθαγόραν εἰς Ὀρφέα ἀνενεγκεῖν τινα ἱστορεῖ. The verbal agreement, except for τινα ἱστορεῖ, is exact.) They further attribute to him the Scopiads which begins thus:

    Be not shameless, before any man.
    Sosicrates in his Successions of Philosophers says that, when Leon the tyrant of Phlius asked him who he was, he said, A philosopher,[*](Cf. i. 12, whence it would seem that Sosicrates used Heraclides of Pontus as his authority for this anecdote.) and that he compared life to the Great Games, where some went to
    V2_329
    compete for the prize and others went with wares to sell, but the best as spectators; for similarly, in life, some grow up with servile natures, greedy for fame and gain, but the philosopher seeks for truth. Thus much for this part of the subject.

    The contents in general of the aforesaid three treatises of Pythagoras are as follows. He forbids us to pray for ourselves, because we do not know what will help us. Drinking he calls, in a word, a snare, and he discountenances all excess, saying that no one should go beyond due proportion either in drinking or in eating. Of sexual indulgence, too, he says, Keep to the winter for sexual pleasures, in summer abstain; they are less harmful in autumn and spring, but they are always harmful and not conducive to health. Asked once when a man should consort with a woman, he replied, When you want to lose what strength you have.

    He divides man’s life into four quarters thus: Twenty years a boy, twenty years a youth, twenty years a young man, twenty years an old man; and these four periods correspond to the four seasons, the boy to spring, the youth to summer, the young man to autumn, and the old man to winter, meaning by youth one not yet grown up and by a young man a man of mature age. According to Timaeus, he was the first to say, Friends have all things in common and Friendship is equality; indeed, his disciples did put all their possessions into one common stock. For five whole years they had to keep silence, merely listening to his discourses without seeing him, [*](Because he lectured at night;cf.§ 15 νυκτερινὴ ἀκρόασις.) until they passed an examination, and thenceforward they were admitted to his house and allowed to see him. They would never

    V2_331
    use coffins of cypress, because the sceptre of Zeus was made from it, so we are informed by Hermippus in his second book On Pythagoras.

    Indeed, his bearing is said to have been most dignified, and his disciples held the opinion about him that he was Apollo come down from the far north. There is a story that once, when he was disrobed, his thigh was seen to be of gold; and when he crossed the river Nessus, quite a number of people said they heard it welcome him. According to Timaeus in the tenth book of his History, he remarked that the consorts of men bore divine names, being called first Virgins, then Brides, and then Mothers.[*](The allusion is to the Nymphs and the heavenly pair, mother and daughter (Demeter and Persephone).) He it was who brought geometry to perfection, while it was Moeris who first discovered the beginnings of the elements of geometry: Anticlides in his second book On Alexander[*](Scriptorum Alex. ill. fr. p. 147.) affirms this,

    and further that Pythagoras spent most of his time upon the arithmetical aspect of geometry; he also discovered the musical intervals on the monochord. Nor did he neglect even medicine. We are told by Apollodorus the calculator that he offered a sacrifice of oxen on finding that in a right-angled triangle the square on the hypotenuse is equal to the squares on the sides containing the right angle. And there is an epigram running as follows[*](Anth. Pal. vii. 119.):

      What time Pythagoras that famed figure found,
    1. For which the noble offering he brought.

    He is also said to have been the first to diet athletes on meat, trying first with Eurymenes[*](The story of Eurymenes was known to Porphyry, Vit. Pyth. 18. We can still see how these quotations made by D. L. himself from Favorinus disturb the context.)— so we learn from Favorinus in the third book of his Memorabilia—whereas in former times they had

    V2_333
    trained on dried figs, on butter,[*](Or rather soft cheese;cf. supra,i. § 7, note.) and even on wheatmeal, as we are told by the same Favorinus in the eighth book of his Miscellaneous History.

    Some say it was a certain trainer named Pythagoras who instituted this diet,[*](Cf. Iamblichus, Vit. Pyth. 25, and Porphyry, De abstinentia, i. 26.) and not our Pythagoras, who forbade even the killing, let alone the eating, of animals which share with us the privilege of having a soul. This was the excuse put forward; but his real reason for forbidding animal diet was to practise people and accustom them to simplicity of life, so that they could live on things easily procurable, spreading their tables with uncooked foods and drinking pure water only, for this was the way to a healthy body and a keen mind. Of course the only altar at which he worshipped was that of Apollo the Giver of Life, behind the Altar of Horns at Delos, for thereon were placed flour and meal and cakes, without the use of fire, and there was no animal victim, as we are told by Aristotle in his Constitution of Delos.

    He was the first, they say, to declare that the soul, bound now in this creature, now in that, thus goes on a round ordained of necessity. He too, according to Aristoxenus the musician, was the first to introduce weights and measures into Greece. It was he who first declared that the Evening and Morning Stars are the same, as Parmenides maintains.[*](Cf. inf. ix. 23.) So greatly was he admired that his disciples used to be called prophets to declare the voice of God, besides which he himself says in a written work that after two hundred and seven years in Hades he has returned to the land of the living. Thus it was that they remained his staunch adherents,

    V2_335
    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 Miscellaneous History.[*](See, however, Porphyry, Vit. Pyth. 4, who cites as his authority Timaeus the Sicilian historian (F.H.G. i. p. 211, Fr. 78), who was not improbably the source used by Favorinus.) 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.
