There would appear to be a law determining the _site_, as well as the _character_, of great events. It has often been remarked, that there is a resemblance between all the great battle-fields of the world. One attribute in especial they all possess, namely, that of vastness; inspiring the mind of the spectator with an idea of grandeur, to which the recollection of the carnage of which they were the scene adds a feeling of melancholy. The Troy and the Marathon of the ancient world have found their representative in the modern one, in that gloomy expanse in Flanders where Napoleon witnessed the total defeat of his arms and the final overthrow of his fortunes. We would make the same remark regarding great capitals. There is a family likeness in their sites. The chief cities of the ancient world arose, for the most part, on extensive plains, nigh some great river; for rivers were the railroads of early times. I might instance queenly Thebes, which arose in the great valley of the Nile, with a boundary of fine mountains encircling the plain on which it stood. Babylon found a seat on the great plain of Chaldea, on the banks of the Euphrates. Niniveh arose on the same great plain, on the banks of the Tigris, with the glittering line of the snowy Kurdistan chain bounding its horizon. To come down to comparatively modern times, ROME has been equally fortunate with her predecessors in a site worthy of her greatness and renown. No one needs to be told that the seat of that city, which for so many ages held the sceptre of the world, is the CAMPAGNA DI ROMA.
