Note 99 — BOOK I.
Charles Duke Yonge translation
The best commentators on this passage agree that Cicero does not mean that Aristotle affirmed that there was no such person as Orpheus, but that there was no such poet, and that the verse called Orphic was said to be the invention of another. The passage of Aristotle to which Cicero here alludes has, as Dr. Davis observes, been long lost.
