The Greeks, lying encamped on the mountains, could watch every movement of the Persians on the plain below, while they were enabled completely to mask their own.  Miltiades also had, from, his position, the power of giving battle whenever he pleased, or of delaying it at his discretion, unless Datis were to attempt the perilous operation of storming the heights.

If we turn to the map of the Old World, to test the comparative territorial resources of the two states whose armies were now about to come into conflict, the immense preponderance of the material power of the Persian king over that of the Athenian republic is more striking than any similar contrast which history can supply.  It has been truly remarked that, in estimating mere areas Attica, containing on its whole surface only seven hundred square miles, shrinks into insignificance if compared with many a baronial fief of the Middle Ages, or many a colonial allotment of modern times.  Its antagonist, the Persian, empire, comprised the whole of modern Asiatic and much of modern European Turkey, the modern kingdom of Persia and the countries of modern Georgia, Armenia, Balkh, the Punjaub, Afghanistan, Beloochistan, Egypt and Tripoli.

Nor could a European, in the beginning of the fifth century before our era, look upon this huge accumulation of power beneath the sceptre of a single Asiatic ruler with the indifference with which we now observe on the map the extensive dominions of modern Oriental sovereigns; for, as has been already remarked, before Marathon was fought, the prestige of success and of supposed superiority of race was on the side of the Asiatic against the European.  Asia was the original seat of human societies, and long before any trace can be found of the inhabitants of the rest of the world having emerged from the rudest barbarism, we can perceive that mighty and brilliant empires flourished in the Asiatic continent.  They appear before us through the twilight of primeval history, dim and indistinct, but massive and majestic, like mountains in the early dawn.

Instead, however, of the infinite variety and restless change which has characterized the institutions and fortunes of European states ever since the commencement of the civilization of our continent, a monotonous uniformity pervades the histories of nearly all Oriental empires, from the most ancient down to the most recent times.  They are characterized by the rapidity of their early conquests, by the immense extent of the dominions comprised in them, by the establishment of a satrap or pashaw system of governing the provinces, by an invariable and speedy degeneracy in the princes of the royal house, the effeminate nurslings of the seraglio succeeding to the warrior sovereigns reared in the camp, and by the internal anarchy and insurrections which indicate and accelerate the decline and fall of these unwieldy and ill-organized fabrics of power.
