Aristocracy was the soul of the Dorian political constitutions, and the towns of Magna Græcia were all Dorian colonies; but in consequence of their extensive commerce the tendency of the people was at that time towards democracy. To preserve the aristocratic principle was the object of Pythagoras; but he wished to make the aristocracy not merely one of birth; he desired that, like the sacerdotal castes of the East, it should also have the supremacy in knowledge. As his system was contrary to the general feeling, Pythagoras saw that it was only by gaining the veneration of the people that he could carry it into effect; and by his personal advantages of beauty of form, skill in gymnastic exercises, eloquence, and dignity, he drew to himself the popular favour by casting the mantle of mystery over his doctrines. He thus at once inspired the people with awe for them, and the nobles with zeal to become initiated in his secrets. The most perfect success, we are told, attended the project of the philosopher. A total change of manners took place in Croton; the constitution became nearly Spartan; a body of 300 nobles, rendered by the lessons of the sage as superior to the people in knowledge of every kind as they were in birth, ruled over it. The nobles of the other states flocked to Croton to learn how to govern by wisdom; Pythagorean missionaries went about everywhere preaching the new political creed; they inculcated on the people religion, humility, and obedience; such of the nobles as were deemed capable were initiated in the wisdom of the order, and taught its maxims and principles; a golden age, in which power was united with wisdom and virtue, seemed to have begun upon earth.
