520 PROSPECTS OF THE WESTERN CIVILIZATION to the 6th August, A.D. 1945, when an atomic bomb was dropped on Hiroshima. Let us suppose, however, that the Babylonic, Egyptiac, and Syriac civilizations had been 2,425 years ahead of a latter-day Western Civilization in the development of Military Technology. The supposi- tion is not fantastic, considering that, in some branches of Technology, these older civilizations were at least that much in advance; and, if we allow this licence to our imagination, we may find ourselves puzzled to estimate how Leonidas and his three hundred would have acted in circum- stances that would have stultified most of the considerations that are attributed to them. Suppose that Xerxes' invading army had not been constrained, as it was, by the state of Military Technology at the time, to kill Leonidas and his three hundred companions in hand-to-hand combat with swords and spears, or at short range with arrows; suppose that they had had a stock of two atomic bombs, one to drop on the Greek force at Thermopy- lae, and another to drop simultaneously on Sparta—or, better still, that they had had a single hydrogen bomb whose explosion would instan- taneously have destroyed all life in Continental European Greece and in the Aegean Archipelago before the Achaemenian expeditionary force had started cautiously to advance from its assembly-point in the interior of Anatolia: in those then inconceivable circumstances there would have been no perpetuation of the three hundred devotees' families, since the sons whom they had left behind at home would have been killed at the same instant as their fathers; there would have been no Sparta to receive the news of the three hundred heroes' faithfulness unto death1 and to remember their deed and their names; no Simonides to compose an epitaph; and no monumental mason to engrave it. The presupposition of the three hundred Spartiates' self-sacrifice was an assurance—which, in these hypothetical circumstances, would have been denied to them— that, in giving their lives, they were saving their country's existence; and this was likewise the theme of another epitaph composed by Simonides in commemoration, not of Spartiates who had fallen in defence of Sparta against Achaemenian aggression, but of Tegeatans who had fallen in defence of Tegea against Lacedaemonian aggression some years later.
