From Scepsis came the Socratic philosophers Erastus and Coriscus and Neleus the son of Coriscus, this last a man who not only was a pupil of Aristotle and Theophrastus, but also inherited the library of Theophrastus, which included that of Aristotle. At any rate, Aristotle bequeathed his own library to Theophrastus, to whom he also left his school; and he is the first man, so far as I know, to have collected books and to have taught the kings in Egypt how to arrange a library. Theophrastus bequeathed it to Neleus; and Neleus took it to Scepsis and bequeathed it to his heirs, ordinary people, who kept the books locked up and not even carefully stored. But when they heard bow zealously the Attalic kings1
to whom the city was subject were searching for books to build up the library in Pergamum, they hid their books underground in a kind of trench. But much later, when the books had been damaged by moisture and moths, their descendants sold them to Apellicon2
of Teos for a large sum of money, both the books of Aristotle and those of Theophrastus. But Apellicon was a bibliophile rather than a philosopher; and therefore, seeking a restoration of the parts that had been eaten through, he made new copies of the text, filling up the gaps incorrectly, and published the books full of errors. The result was that the earlier school of Peripatetics who came after Theophrastus had no books at all, with the exception of only a few, mostly exoteric works, and were therefore able to philosophize about nothing in a practical way, but only to talk bombast about commonplace propositions, whereas the later school, from the time the books in question appeared, though better able to philosophise and Aristotelise, were forced to call most of their statements probabilities, because of the large number of errors.3
Rome also contributed much to this; for, immediately after the death of Apellicon, Sulla, who had captured Athens, carried off Apellicon's library to Rome, where Tyrannion the grammarian, who was fond of Aristotle, got it in his hands by paying court to the librarian, as did also certain booksellers who used bad copyists and would not collate the texts—a thing that also takes place in the case of the other books that are copied for selling, both here4
and at Alexandria. However, this is enough about these men.
