As he grew older there arose a special reason why he should become able to speak for himself. His father, who was also named Demosthenes, had been a rich man. He was a manufacturer of swords or knives, in which he employed thirty-two slaves; and also had a couch or bed factory, employing twenty more. His mother was the daughter of a rich corn-dealer of the Bosphorus. The father died when his son was seven years old, leaving his estate in the care of three guardians. These were rich men, and relatives and friends, whom he thought he could safely trust; the more so as he left them legacies in his will. Yet they proved rogues, and when Demosthenes became sixteen years of age--which made him a man under the civil law of Athens--he found that the guardians had made way with nearly the whole of his estate. Of fourteen talents bequeathed him there were less than two left. The boy complained and remonstrated in vain. The guardians declared that the will was lost; their accounts were plainly fraudulent; they evidently proposed to rob their ward of his patrimony. This may seem to us to have been a great misfortune. It was, on the contrary, the greatest good fortune. It forced Demosthenes to become an orator. Though he never recovered his estate, he gained a fame that was of infinitely greater value. The law of Athens required that every plaintiff should plead his own cause, either in person or by a deputy speaking his words. Demosthenes felt that he must bring suit or consent to be robbed. That art of oratory, towards which he had so strong an inclination, now became doubly important. He must learn how to plead eloquently before the courts, or remain the poor victim of a party of rogues. This determined the young student of rhetoric. He would make himself an orator. He at once began an energetic course of study. There were then two famous teachers of oratory in Athens, Isocrates and Isaeus. The school of Isocrates was famous, and his prices very high. The young man, with whom money was scarce, offered him a fifth of his price for a fifth of his course, but Isocrates replied that his art, like a good fish, must be sold entire. He then turned to Isaeus, who was the greatest legal pleader of the period, and studied under him until he felt competent to plead his own case before the courts. Demosthenes soon found that he had mistaken his powers. His argument was formal and long-winded. His uncouth style roused the ridicule of his hearers. His voice was weak, his breath short, his manner disconnected, his utterance confused. His pronunciation was stammering and ineffective, and in the end he withdrew from the court, hopeless and disheartened.
