Ἀμφίων

This man [was the] discoverer of ancient music.¹ Concerning him, the Transgressor says in a letter: "for you have leisure, and you possess a fine nature, and you love philosophy, if anyone ever has; these three things coming together at the same time were enough to reveal Amphion as the discoverer of ancient music - time, divine inspiration, a love of hymnody. For not even the lack of tools is enough to stand in the way of these, and he who has a share in these three might easily discover them: for indeed do we not accept the tradition that this man discovered not only the scales but also the lyre itself with them, either by using a rather marvellous intelligence or some divine gift, through an unassisted success? And most of the ancients, especially excelling in these three things, seemed in truth to have been philosophers, as they needed nothing else."²
Zethos and another Amphion: look under Antiope.³
