III. The relief of debtors was a device peculiar to Solon, which, more than anything else confirmed the liberty of the citizens. For laws to establish equality are of no use if poor men are prevented from enjoying it because of their debts; and in the states which appear to be the most free, men become mere slaves to the rich, and conduct the whole business of the state at their dictation. It should be especially noted that although an abolition of debt would naturally produce a civil war, yet this measure of Solon's, like an unusual but powerful dose of medicine, actually put an end to the existing condition of internal strife; for the well-known probity of Solon's character outweighed the discredit of the means to which he resorted. In fact Solon began his public life with greater glory than Poplicola, for he was the leading spirit, and followed no man, but entirely single handed effected the most important reforms; while Poplicola was more enviable and fortunate at the close of his career. Solon himself saw his own constitution overthrown, while that of Poplicola preserved order in the city down to the time of the civil wars; and the reason was that Solon, as soon as he had enacted his laws, went on his travels, leaving them written on wooden tablets, defenceless against all assailants; whereas Poplicola remained at home, acted as consul, and by his statesmanship ensured the success and permanence of the new constitution. Moreover, Solon could not stop Peisistratus, although he perceived his designs, but was forced to see a despotism established; while Poplicola destroyed a monarchy which had existed for many years, showing equal virtue with Solon, but greater good fortune and power to enable him to carry out his intentions. IV. With regard to warlike achievements, Daimachus of Plataea will not even admit that Solon made the campaign against the Megarians, which we have related; but Poplicola both by strategy and personal valour won many great battles. As a statesman, Solon seems to have acted somewhat childishly in pretending that he was mad, in order to make his speech about Salamis, while Poplicola ran the very greatest risks in driving out the tyrant and crushing the conspiracy. He was especially responsible for the chief criminals being put to death, and thus not only drove the Tarquins out of the city, but cut off and destroyed their hopes of return. And while he showed such vigour in enterprises that required spirit and courage, he was equally admirable in peaceful negotiations and the arts of persuasion; for he skilfully won over the formidable Porsena to be the friend instead of the enemy of Rome.
