The history of this Crates was distinguished by the one solitary romance of Greek philosophy. A young lady of noble family, named Hipparchia, fell desperately in love with him, refused several most eligible suitors, and threatened to kill herself unless she was given to him in marriage. Her parents in despair sent for Crates. Marriage, for a philosopher, was against the principles of his sect, and he at first joined them in endeavouring to dissuade her. Finding his remonstrances unavailing, he at last flung at her feet the staff and wallet which constituted his whole worldly possessions, exclaiming, ‘Here is the bridegroom, and that is the dower. Think of this matter well, for you cannot be my partner unless you follow the same calling with me.’ Hipparchia consented, and thenceforth, heedless of taunts, conformed her life in every respect to the Cynic pattern.[13] Zeno had more delicacy or less fortitude than Hipparchia; and the very meagre intellectual fare provided by Crates must have left his inquisitive mind unsatisfied. Accordingly we find him leaving this rather disappointing substitute for Socrates, to study philosophy under Stilpo the Megarian dialectician and Polemo the head of the Academy;[14] while we know that he must have gone back to Heracleitus for the physical basis from which contemporary speculation had by this time cut itself completely free. At length, about the beginning of the third century B.C., Zeno, after having been a learner for twenty years, opened a school on his own account. As if to mark the practical bearing of his doctrine he chose one of the most frequented resorts in the city for its promulgation. There was at Athens a portico called the Poecile Stoa, adorned with frescoes by Polygnôtus, the greatest painter of the Cimonian period. It was among the monuments of that wonderful city, at once what the Loggia dei Lanzi is to Florence, and what Raphael’s Stanze are to Rome; while, like the Place de la Concorde in Paris, it was darkened by the terrible associations of a revolutionary epoch. A century before Zeno’s time fourteen hundred Athenian citizens had been slaughtered under its colonnades by order of the Thirty. ‘I will purify the Stoa,’ said the Cypriote stranger;[15] and the feelings still associated with the word Stoicism prove how nobly his promise was fulfilled.
