Plato indeed wrote to him that the eyes of all the world were now upon him; but it is evident that he himself had fixed his eye upon one place in one city, the Academy, and considered that the spectators and judges there regarded not great actions, courage, or fortune, but watched to see how temporately and wisely he could use his prosperity, how evenly he could behave himself in the high condition he now was in. Neither did he remit anything of his wonted stateliness in conversation or serious charge to the people; he made it rather a point to maintain it, notwithstanding that a little condescension and obliging civility were very necessary for his present affairs; and Plato, as we said before, rebuked him, and wrote to tell him that self-will keeps house with solitude. But certainly his natural temperament was one that could not bend to complaisance; and, besides, he wished to work the Syracusans back the other way, out of their present excess of license and caprice.
Heraclides began again to set up against him, and, being invited by Dion to make one of the Council, refused to come, saying he would give his opinion as a private citizen in the public assembly. Next he complained of Dion because he had not demolished the citadel, and because he had hindered the people from throwing down Dionysius's tomb and doing despite to the dead; moreover, he accused him for sending to Corinth for counsellors and assistants in the government, thereby neglecting and slighting his fellow-citizens. And indeed he had sent messages for some Corinthians to come to him, hoping by their means and presence the better to settle that constitution he intended; for he designed to suppress the unlimited democratic government, which indeed is not a government, but, as Plato calls it, a market-place of governments, and to introduce and establish a mixed polity, on a Spartan and Cretan model, between a commonwealth and a monarchy, wherein an aristocratic body should preside, and determine all matters of greatest consequence; for he saw also that the Corinthians were chiefly governed by something like an oligarchy, and the people but little concerned in public business.
Now knowing that Heraclides would be his most considerable adversary, and that in all ways he was a turbulent, fickle, and factious man, he gave way to some whom formerly he hindered when they designed to kill him, who, breaking in, murdered Heraclides in his own house. His death was much resented by the citizens.
Nevertheless, when Dion made him a splendid funeral, followed the dead body with all his soldiers, and then addressed them, they understood that it would have been impossible to have kept the city quiet, as long as Dion and Heraclides were competitors in the government.
Dion had a friend called Callippus, an Athenian, who, Plato says, first made acquaintance and afterwards obtained familiarity with him, not from any connection with his philosophic studies, but on occasion afforded by the celebration of the mysteries, and in the way of ordinary society. This man went with him in all his military service, and was in great honour and esteem; being the first of his friends who marched by his side into Syracuse, wearing a garland upon his head, having behaved himself very well in all the battles, and made himself remarkable for his gallantry. He, finding that Dion's principal and most considerable friends were cut off in the war, Heraclides now dead, and the people without a leader, and that the soldiers had a great kindness for him, like a perfidious and wicked villain, in hopes to get the chief command of Sicily as his reward for the ruin of his friend and benefactor, and, as some say, being also bribed by the enemy with twenty talents to destroy Dion, inveigled and engaged several of the soldiers in a conspiracy against him, taking this cunning and wicked occasion for his plot. He daily informed Dion of what he heard or what he feigned the soldiers said against him; whereby he gained that credit and confidence, that he was allowed by Dion to consort privately with whom he would, and talk freely against him in any company, that he might discover who were his secret and factious maligners. By this means, Callippus in a short time got together a cabal of all the seditious malcontents in the city; and if any one who would be drawn in advised Dion that he was tampered with, he was not troubled or concerned at it, believing Callippus did it in compliance with his directions.
While this conspiracy was afoot, a strange and dreadful apparition was seen by Dion. As he sat one evening in a gallery in his house, alone and thoughtful, hearing a sudden noise he turned about, and saw at the end of the colonnade, by clear daylight, a tall woman, in her countenance and garb like one of the tragical Furies, with a broom in her hand, sweeping the floor. Being amazed and extremely affrighted, he sent for some of his friends, and told them what he had seen, entreating them to stay with him and keep him company all night;for he was excessively discomposed and alarmed, fearing that if he were left alone the spectre would again appear to him. He saw it no more. But a few days after, his only son, being almost grown up to man's estate, upon some displeasure and pet he had taken upon a childish and frivolous occasion, threw himself headlong from the top of the house and broke his neck.
