Solon is said to have been aware that he had left many imperfections in his laws. He described them not as the best laws which he could devise, but as the best which the Athenians could receive. Having bound the government and people of Athens by a solemn oath to observe his institutions for at least ten years, he left Athens and travelled in foreign lands. During his absence the old dissensions between the Plain, the Shore, and the Mountain broke out afresh with more violence than ever. The first was headed by Lycurgus, the second by Megacles, an Alcmaeonid, and the third by Pisistratus, the cousin of Solon. Of these leaders, Pisistratus was the ablest and the most dangerous. He had espoused the cause of the poorest of the three classes, in order to gain popularity, and to make himself master of Athens. Solon on his return to Athens detected the ambitious designs of his kinsman, and attempted to disuade him from them. Finding his remonstrances fruitless, he next denounced his projects in verses addressed to the people. Few, however, gave any heed to his warnings: and Pisistratus, at length finding his schemes ripe for action, had recourse to a memorable strategem to secure his object. One day he appeared in the market-place in a chariot, his mules and his own person bleeding with wounds inflicted with his own hands. These he exhibited to the people, telling them that he had been nearly murdered in consequence of defending their rights. The popular indignation was excited; and a guard of fifty clubmen was granted him for his future security. He gradually increased the number of his guard and soon found himself strong enough to throw off the mask and seize the Acropolis (B.C. 560). Megacles and the Alcmaeonidae left the city. Solon alone had the courage to oppose the usurpation, and upbraided the people with their cowardice and their treachery. "You might," said he, "with ease have crushed the tyrant in the bud; but nothing now remains but to pluck him up by the roots." But no one responded to his appeal. He refused to fly; and when his friends asked him on what he relied for protection, "On my old age," was his reply. It is creditable to Pisistratus that he left his aged relative unmolested, and even asked his advice in the administration of the government. Solon did not long survive the overthrow of the constitution. He died a year or two afterwards at the advanced age of eighty. His ashes are said to have been scattered by his own direction round the island of Salamis, which he had won for the Athenian people.
