Andronicus of Rhodes (first century B.C.), Greek philosopher, a leading member of the Lyceum who was largely responsible for establishing the canon of Aristotle’s works still read today. He also edited the works of Theophrastus. At the time, Aristotle was known primarily for his philosophical dialogues, only fragments of which now survive; his more methodical treatises had stopped circulating soon after his death. By producing the first systematic edition of Aristotle’s corpus, Andronicus revived study of the treatises, and the resulting critical debates dramatically affected the course of philosophy. Little is recorded about Andronicus’s labors; but besides editing the texts and discussing titles, arrangement, and authenticity, he sought to explicate and assess Aristotle’s thought. In so doing, he and his colleagues initiated the exegetical tradition of Aristotelian commentaries. Nothing he wrote survives; a summary account of emotions formerly ascribed to him is spurious.
