Strabo has given a melancholy history of these works, in the ninth book of his geography. Aristotle, as we have stated above, had bequeathed them to Theophrastus, the most distinguished of his pupils, and his successor in the school. That philosopher left them, together with his own works, to his scholar Neleus, who carried them to his native city, Scepsis in Asia Minor. The heirs of Neleus, who were unlettered men, kept them locked up; and when they understood that the King of Pergamos, to whom the town belonged, was collecting books, to form a library on the plan of the Alexandrian, they concealed them in a vault or cellar, where they lay forgotten 130 years. When accidentally discovered, at the end of that period, they were found to be greatly injured by damp and vermin. At length they were sold to an inhabitant of Athens, named Apellicon, who, however, was not so much a lover of philosophy as a collector of manuscripts, and who adulterated the original text by his injudicious emendations and interpolations. Several copies thus altered were published by him. When Athens was taken by Sylla, the library of this citizen was carried to Rome, where the works of Aristotle were corrected by Tyrannion, a grammarian. Andronicus of Rhodes afterwards arranged the whole into sections, and gave them to the world. According to Dr Gillies, Aristotle must have "composed above 400 different treatises, of which only forty-eight have been transmitted to the present age. But many of these last consist of several books; and the whole of his remains together still form a golden stream of Greek erudition, exceeding four times the collective bulk of the Iliad and Odyssey."
