Thus Dionysius was in constant dread. He had a wide trench round his bedroom, with a drawbridge that he drew up and put down with his own hands; and he put one barber to death for boasting that he held a razor to the tyrant's throat every morning. After this he made his young daughters shave him; but by and by he would not trust them with a razor, and caused them to singe of his beard with hot nutshells! He was said to have put a man named Antiphon to death for answering him, when he asked what was the best kind of brass, 'That of which the statues of Harmodius and Aristogeiton were made.' These were the two Athenians who had killed the sons of Pisistratus the tyrant, so that the jest was most offensive, but its boldness might have gained forgiveness for it. One philosopher, named Philoxenus, he sent to a dungeon for finding fault with his poetry, but he afterwards composed another piece, which he thought so superior, that he could not be content without sending for this adverse critic to hear it. When he had finished reading it, he looked to Philoxenus for a compliment; but the philosopher only turned round to the guards, and said dryly, 'Carry me back to prison.' This time Dionysius had the sense to laugh, and forgive his honesty. All these stories may not be true; but that they should have been current in the ancient world shows what was the character of the man of whom they were told, how stern and terrible was his anger, and how easily it was incurred. Among those who came under it was a Pythagorean called Pythias, who was sentenced to death, according to the usual fate of those who fell under his suspicion. Pythias had lands and relations in Greece, and he entreated as a favor to be allowed to return thither and arrange his affairs, engaging to return within a specified time to suffer death. The tyrant laughed his request to scorn. Once safe out of Sicily, who would answer for his return? Pythias made reply that he had a friend, who would become security for his return; and while Dionysius, the miserable man who trusted nobody, was ready to scoff at his simplicity, another Pythagorean, by name of Damon, came forward, and offered to become surety for his friend, engaging, if Pythias did not return according to promise, to suffer death in his stead. Dionysius, much astonished, consented to let Pythias go, marveling what would be the issue of the affair. Time went on and Pythias did not appear. The Syracusans watched Damon, but he showed no uneasiness. He said he was secure of his friend's truth and honor, and that if any accident had cause the delay of his return, he should rejoice in dying to save the life of one so dear to him.
