From the preface of The Spartans, The World of the Warrior-Heroes of Ancient Greece by Paul Cartledge, 2004: "Who were the ancient Spartans, and why should we care? The events of 11 September 2001 jolted many of us into rethinking what was distinctive and distinctively admirable - or at least defensible - about Western civilization, values and culture. Some of us were provoked into wondering aloud whether any definition of that civilization and its cultural values would justify our dying for them, or even maybe killing for them. Those of us who are historians or ancient Greece wondered this with especial intensity, since the world of ancient Greece is one of the principal tap roots of Western civilization. As J. S. Mill put it, the battle of Marathon, fought in 459 BC between the Athenians, with the support from the Plataeans and the invading Persians, was much more important than the Battle of Hastings, even as an event in English history. "So too, arguably, as we shall see, was the battle of Thermopylae of ten years later. This was a defeat for the small, Spartan-led Greek force at the hands of the overwhelmingly larger force of Persian and other invaders, yet it gave hope of better times to come, and its cultural significance is inestimable. Indeed, some would say that Thermopylae was Sparta's finest hour. "Thus, one not insignificant reason why we today should care who the ancient Spartans were, is that they played a key role - some might say the key role - in defending Greece and so preserving from foreign and alien conquest a form of culture or civilization that constitutes one of the chief roots of our own Western civilization."
