Andronicus of Rhodes (c. 70 B.C.), was the eleventh scholarch of the Peripatetics. His chief work was the arrangement of the writings of Aristotle and Theophrastus with materials supplied to him by Tyrannion . Before his time, Aristotle's dialogues were widely known, but his treatises had been lost in obscurity. Besides arranging the works, he seems to have written paraphrases and commentaries, none of which is extant. Two treatises are sometimes erroneously attributed to him, one on the Emotions, the other a commentary on Aristotle's Ethics (really by Constantine Palaeocappa in the 16th century, or by John Callistus of Thessalonica).
