Book 9
5.26
He was a truly noble character both as philosopher and as politician; at all events, his extant books are brimful of intellect. Again, he plotted to overthrow Nearchus the tyrant (or, according to others, Diomedon) but was arrested: so Heraclides in his epitome of Satyrus. On that occasion he was crossexamined as to his accomplices and about the arms which he was conveying to Lipara; he denounced all the tyrant’s own friends, wishing to make him destitute of supporters. Then, saying that he had something to tell him about certain people in his private ear, he laid hold of it with his teeth and did not let go until stabbed to death, meeting the same fate as Aristogiton the tyrannicide.
