Therefore, Demosthenes, having heard the tutors and school-masters agreeing among themselves to be present at this trial, with much importunity persuades his tutor to take him along with him to the hearing; who, having some acquaintance with the doorkeepers, procured a place where the boy might sit unseen, and hear what was said. Callistratus having got the day, and being much admired, the boy began to look upon his glory with a kind of emulation, observing how he was courted on all hands, and attended on his way by the multitude;but his wonder was more than all excited by the power of his eloquence, which seemed able to subdue and win over anything. From this time, therefore, bidding farewell to other sorts of learning and study, he now began to exercise himself, and to take pains in declaiming, as one that meant to be himself also an orator. He made use of Isaeus as his guide to the art of speaking, though Isocrates at that time was giving lessons; whether, as some say, because he was an orphan, and was not able to pay Isocrates his appointed fee of ten minae or because he preferred Isaeus's speaking, as being more businesslike and effective in actual use. Hermippus says that he met with certain memoirs without any author's name, in which it was written that Demosthenes was a scholar to Plato, and learnt much of his eloquence from him; and he also mentions Ctesibius, as reporting from Callias of Syracuse and some others, that Demosthenes secretly obtained a knowledge of the systems of Isocrates and Alcidamas, and mastered them thoroughly.
As soon, therefore, as he was grown up to man's estate, he began to go to law with his guardians, and to write orations against them;who, in the meantime, had recourse to various subterfuges and pleas for new trials, and Demosthenes, though he was thus, as Thucydides says, taught his business in dangers, and by his own exertions was successful in his suit, was yet unable for all this to recover so much as a small fraction of his patrimony. He only attained some degree of confidence in speaking, and some competent experience in it. And having got a taste of the honour and power which are acquired by pleadings, he now ventured to come forth, and to undertake public business. And, as it is said of Laomedon, the Orchomenian, that, by advice of his physician, he used to run long distances to keep off some disease of his spleen, and by that means having, through labour and exercise, framed the habit of his body, he betook himself to the great garland games, and became one of the best runners at the long race; so it happened to Demosthenes, who, first venturing upon oratory for the recovery of his own private property, by this acquired ability in speaking, and at length, in public business, as it were in the great games, came to have the pre-eminence of all competitors in the assembly. But when he first addressed himself to the people, he met with great discouragements, and was derided for his strange and uncouth style, which was cumbered with long sentences and tortured with formal arguments to a most harsh and disagreeable excess.
Besides, he had, it seems, a weakness in his voice, a perplexed and indistinct utterance and a shortness of breath, which, by breaking and disjointing his sentences, much obscured the sense and meaning of what he spoke. So that in the end being quite disheartened, he forsook the assembly; and as he was walking carelessly and sauntering about the Piraeus, Eunomus, the Thriasian, then a very old man, seeing him, upbraided him, saying that his diction was very much like that of Pericles, and that he was wanting to himself through cowardice and meanness of spirit, neither bearing up with courage against popular outcry, nor fitting his body for action, but suffering it to languish through mere sloth and negligence.
Another time, when the assembly had refused to hear him, and he was going home with his head muffled up, taking it very heavily, they relate that Satyrus, the actor, followed him, and being his familiar acquaintance, entered into conversation with him. To whom, when Demosthenes bemoaned himself, that having been the most industrious of all the pleaders, and having almost spent the whole strength and vigour of his body in that employment, he could not yet find any acceptance with the people, that drunken sots, mariners, and illiterate fellows were heard, and had the husting's for their own, while he himself was despised, "You say true, Demosthenes,"replied Satyrus, "but I will quickly remedy the cause of all this, if you will repeat to me some passage out of Euripides or Sophocles." Which when Demosthenes had pronounced, Satyrus presently taking it up after him, gave the same passage, in his rendering of it, such a new form, by accompanying it with the proper mien and gesture, that to Demosthenes it seemed quite another thing. By this, being convinced how much grace and ornament language acquires from action, he began to esteem it a small matter, and as good as nothing for a man to exercise himself in declaiming, if he neglected enunciation and delivery. Hereupon he built himself a place to study in under ground (which was still remaining in our time), and hither he would come constantly every day to form his action and to exercise his voice; and here he would continue, oftentimes without intermission, two or three months together, shaving one half of his head, that so for shame he might not go abroad, though he desired it ever so much.
Nor was this all, but he also made his conversation with people abroad, his common speech, and his business, subservient to his studies, taking from hence occasions and arguments as matter to work upon. For as soon as he was parted from his company, down he would go at once into his study, and run over everything in order that had passed, and the reasons that might be alleged for and against it.
