 The critical engagement with Aristotle that began toward the end of the Hellenistic age and continued throughout the centuries that followed was directed to works such as the Categories, which had been largely ignored in the preceding centuries. This engagement presupposes the availability of Aristotle’s writings in a form that suited the interests and needs of the time. Although the information in our possession is slim, it strongly suggests that an intense editorial activity took place in the 1st century BCE. Apellicon of Teos, a bibliophile rather than a philosopher, seems to have produced copies of Aristotle’s works in the 90s (Strabo, Geo. XIII I 54); Tyrannion of Amisus, a grammarian and enthusiast of Aristotle (philaristotelês), who had access to Apellicon’s books, may have done the same in the 60s (but our sources do not say that he edited the works of Aristotle; they only say that he “put in order the books of Aristotle”; Strabo, Geo. XIII I 54; Plutarch, Sulla 26 468 B-C). According to the tradition, these editorial labors were surpassed by that of Andronicus of Rhodes, who is credited with the production of the first reliable edition of Aristotle; an edition that exercised an enormous influence on the Post-Hellenistic return to Aristotle. More information on Andronicus and his putative edition of Aristotle is available in the
