Institutio Oratoria

It was not therefore without reason that Plato regarded the knowledge of music as necessary to his ideal statesman or politician, as he calls him; while the leaders even of that school, which in other respects is the strictest and most severe of all schools of philosophy, [*](sc. the Stoics.) held that the wise man might well devote some of his attention to such studies. Lycurgus himself, the founder of the stern laws of Sparta, approved of the training supplied by music.
