The antiquities of this plain resolve themselves into the tomb of the Athenians, the monument of Miltiades, and the tomb of the Platæans. Dr. Clarke found also many interesting relics, for an account of which we must refer to his Travels, in order that we may find space for some beautiful remarks, with which he closes his very agreeable account. "If there be a spot upon earth, pre-eminently calculated to awaken the solemn sentiments, which such a view of nature is fitted to make upon all men, it may surely be found in the plain of Marathon; where, amidst the wreck of generations, and the graves of ancient heroes, we elevate our thoughts towards HIM, 'in whose sight a thousand years are but as yesterday;' where the stillness of Nature, harmonizing with the calm solitude of that illustrious region, which once was a scene of the most agitated passions, enables us, by the past, to determine of the future. In those moments, indeed, we may be said to live for ages;--a single instant, by the multitude of impressions it conveys, seems to anticipate for us a sense of that eternity 'when time shall be no more;' when the fitful dream of human existence, with all its turbulent illusions, shall be dispelled; and the last sun having set, in the last of the world, a brighter dawn than ever gladdened the universe, shall renovate the dominions of darkness and of death."[351] NO. LI.--MEGALOPOLIS. This city, situated in Arcadia, had one of the most illustrious persons of ancient times for its founder, Epaminondas. Its population was collected from various small cities and towns of Arcadia. Soon after its establishment, the inhabitants sent to Plato for a code of laws. The philosopher was much pleased with so flattering an offer; but he ultimately declined sending them one, because he learned from a disciple, whom he had sent to Megalopolis, that the inhabitants would never consent to an equality of property. In 232 B.C., Megalopolis joined the Achaian league, and was taken and ruined by Cleomenes. At that period it was as large a city as Sparta. Its most valuable paintings and sculptures were conveyed to the Laconian capital, and great part of the city destroyed. The Athenians, soon after, beginning to see the impropriety of not keeping up the balance of power in Greece, Demosthenes signalised himself greatly in endeavouring to persuade them to take part with the Megalopolitans. "It has been a perpetual maxim with us," said he, "to assist the oppressed against the oppressor. We have never varied from this principle. The reproach of changing, therefore, ought not to fall upon us, but upon those whose injustice and usurpation oblige us to declare against them."
