Lives of the Eminent Philosophers
Book I .
Of songs still sung these verses belong to him:
Here too are certain current apophthegms assigned to him:
I may also cite one of my own, from my first book, Epigrams in Various Metres
Solon inserted one of his own:
That he foresaw the tyranny of Pisistratus is proved by a passage from a poem of his:
Of the songs sung this is attributed to Solon:
The inscription on his statue runs thus:
His apophthegm is: Give a pledge, and suffer for it. A short letter is also ascribed to him.
To him belongs the apophthegm, Know thine opportunity.
and Hipponax thus: More powerful in pleading causes than Bias of Priene.
For this earns most gratitude the headstrong spirit often flashes forth with harmful bane.
His apophthegm was: Moderation is best. And he wrote to Solon the following letter:
There is also an epigram of my own in the Pherecratean metre:
Book II .
I also have written an epigram upon him:
And again he calls Euripides an engine riveted by Socrates. And Callias in The Captives :
This disdainful, lofty spirit of his is also noticed by Aristophanes when he says:
There is another on the circumstances of his death:
Aristippus, however, put on the dress and, as he was about to dance, was ready with the repartee:
The pun upon καινοῦ (new) and καὶ νοῦ (mind as well) recurs vi. 3.
Book III
Moreover, there are verses of Timon which refer to Plato:
Then there is Timon who puns on his name thus:
And Alexis in the Olympiodorus :
Anaxilas, again, in the Botrylion Circe Rich Women
This, they say, was actually inscribed upon his tomb at Syracuse.
But according to others he wrote nothing but two treatises, one On the Solstice and one On the Equinox, regarding all other matters as incognizable. He seems by some accounts to have been the first to study astronomy, 19 the first to predict eclipses of the sun and to fix the solstices; so Eudemus in his History of Astronomy. It was this which gained for him the admiration of Xenophanes and Herodotus and the notice of Heraclitus and Democritus.
And some, including Choerilus the poet, declare that he was the first to maintain the immortality of the soul. He was the first to determine the sun's course from solstice to solstice, and according to some the first to declare the size of the sun to be one seven hundred and twentieth part of the solar circle, and the size of the moon to be the same fraction of the lunar circle. He was the first to give the last day of the month the name of Thirtieth, and the first, some say, to discuss physical problems.
Aristotle 20 and Hippias affirm that, arguing from the magnet and from amber, he attributed a soul or life even to inanimate objects. Pamphila states that, having learnt geometry from the Egyptians, he was the first to inscribe a right-angled triangle in a circle, whereupon he sacrificed an ox. Others tell this tale of Pythagoras, amongst them Apollodorus the arithmetician. (It was Pythagoras who developed to their furthest extent the discoveries attributed by Callimachus in his Iambics to Euphorbus the Phrygian, I mean "scalene triangles" and whatever else has to do with theoretical geometry.) 21
Thales is also credited with having given excellent advice on political matters. For instance, when Croesus sent to Miletus offering terms of alliance, he frustrated the plan; and this proved the salvation of the city when Cyrus obtained the victory. Heraclides makes Thales himself 22 say that he had always lived in solitude as a private individual and kept aloof from State affairs. Some authorities say that he married and had a son Cybisthus; others that he remained unmarried and adopted his sister's son, and that when he was asked why he had no children of his own he replied "because he loved children." The story is told that, when his mother tried to foroe him to marry, he replied it was too soon, and when she pressed him again later in life, he replied that it was too late. Hieronymus of Rhodes in the second book of his Scattered Notes relates that, in order to show how easy it is to grow rich, Thales, foreseeing that it would be a good season for olives, rented all the oil-mills and thus amassed a fortune. 23
His doctrine was that water is the universal primary substance, and that the world is animate and full of divinities. He is said to have discovered the seasons of the year and divided it into 365 days.
He had no instructor, except that he went to Egypt and spent some time with the priests there. Hieronymus informs us that he measured the height of the pyramids by the shadow they cast, taking the observation at the hour when our shadow is of the same length as ourselves. He lived, as Minyas relates, with Thrasybulus, the tyrant of Miletus.
The well-known story of the tripod found by the fishermen and sent by the people of Miletus to all the Wise Men in succession runs as follows. Certain Ionian youths having purchased of the Milesian fishermen their catch of fish, a dispute arose over the tripod which had formed part of the catch. Finally the Milesians referred the question to Delphi, and the god gave an oracle in this form: 24
Who shall possess the tripod? Thus replies
Apollo: "Whosoever is most wise." 25
