Aulus Gellius, Attic Nights 3.16
- This too has been entrusted to history by the most trustworthy men: Plato bought three books of Philolaus the Pythagorean and Aristotle acquired a few volumes of the philosopher Speusippus at inconceivable prices.
It has been said that the philosopher Plato was a man without great financial resources; yet he nevertheless purchased three books of the Pythagorean Philolaus for ten thousand denarii. That amount, some write, Dio of Syracuse, his friend, gave to him. Aristotle too is said to have bought a few books of the philosopher Speusippus after his death for three Attic talents. That is as much as seventy-two thousand sesterces!
The acerbic Timon wrote a very libelous book which is called the Sillos [i.e. “Lampoon”]. In that book, he takes on Plato insultingly for the fact that he bought the book of Pythagorean philosophy for so high a price and that he cobbled together that noble dialogue the Timaeus from it. Here are Timon’s lines on the matter:
And You, Plato: the desire of education seized you
And you bought a small book for a vast sum,
This book is where you learned to write a Timaios.”
XVII. Id quoque esse a gravissimis viris memoriae mandatum, quod tris libros Plato Philolai Pythagorici et Aristoteles pauculos Speusippi philosophi mercati sunt pretiis fidem non capientibus.
1Memoriae mandatum est Platonem philosophum tenui admodum pecunia familiari fuisse atque eum tamen tris Philolai Pythagorici libros decem milibus denarium mercatum. 2 Id ei pretium donasse quidam scripserunt amicum eius Dionem Syracosium. 3 Aristotelem quoque traditum libros pauculos Speusippi philosophi post mortem eius emisse talentis Atticis tribus; ea summa fit nummi nostri sestertia duo et septuaginta milia. 4 Timon amarulentus librum maledicentissimum conscripsit, qui sillos inscribitur. 5 In eo libro Platonem philosophum contumeliose appellat, quod inpenso pretio librum Pythagoricae disciplinae emisset exque eo Timaeum, nobilem illum dialogum, concinnasset. Versus super ea re Timonos hi sunt (fr. 828):
καὶ σύ, Πλάτων· καὶ γάρ σε μαθητείης πόθος ἔσχεν,
πολλῶν δ’ ἀργυρίων ὀλίγην ἠλλάξαο βίβλον,
ἔνθεν ἀπαρχόμενος τιμαιογραφεῖν ἐδιδάχθης.
