There follows a vast army of orators, Athens alone having produced ten remarkable orators [*]( Antiphon, Andocides, Lysias (flor. 403–380), Isocrates (435–338), Isacus, Demosthenes, Aeschines, Lycargus, Hyperides and Dinarchus. ) in the same generation. Of these Dermosthenes is far the greatest: indeed he came to be regarded almost as the sole pattern of oratory. Such is the force and compactness of his language, so muscular his style, so free from tameness and so self-controlled, that you will find nothing in him that is either too much or too little.
The style of Aesehines is fuller and more diffuse, while his lack of restraint gives an appearance of grandeur. But he has more flesh and less muscle. Hyperides has extraordinary charm and point, but is better qualified, not to say more useful, for cases of minor importance.
Lysias belongs to an earlier generation than those whom I have just mentioned. He has subtlety and elegance and, if the orator's sole duty were merely to instruct, it would be impossible to conceive greater perfection. For there is nothing irrelevant or far-fetched in his speeches. None the less I would compare him to a clear spring rather than to a mighty river.
