Crossing seas as smooth as pavements inlaid with turquoise and lapis lazuli, and relieved with marble mountains as clear and famous as marble statues, it was easy to feel all that had been pure and radiant even in the long evening of paganism; but that did not make me forget what strong stars had comforted the inevitable night. The historical moral was the same whether these marble outlines were merely "the isles" seen afar off like sunset clouds by the Hebrew prophets, or were felt indeed as Hellas, the great archipelago of arts and arms praised by the Greek poets; the historic heritage of both descended only to the Greek Fathers. In those wild times and places, the thing that preserved both was the only thing that would have permanently preserved either. It was but part of the same story when we passed the hoary hills that held the primeval culture of Crete, and remembered that it may well have been the first home of the Philistines. It mattered the less by now whether the pagans were best represented by Poseidon the deity or by Dagon the demon. It mattered the less what gods had blessed the Greeks in their youth and liberty; for I knew what god had blessed them in their despair. I knew by what sign they had survived the long slavery under Ottoman orientalism; and upon what name they had called in the darkness, when there was no light but the horned moon of Mahound. If the glory of Greece has survived in some sense, I knew why it had ever survived in any sense. Nor did this feeling of our fixed formation fail me when I came to the very gates of Asia and of Africa; when there rose out of the same blue seas the great harbour of Alexandria; where had shone the Pharos like the star of Hellas, and where men had heard from the lips of Hypatia the last words of Plato. I know the Christians tore Hypatia in pieces; but they did not tear Plato in pieces. The wild men that rode behind Omar the Arab would have thought nothing of tearing every page of Plato in pieces. For it is the nature of all this outer nomadic anarchy that it is capable sooner or later of tearing anything and everything in pieces; it has no instinct of preservation or of the permanent needs of men. Where it has passed the ruins remain ruins and are not renewed; where it has been resisted and rolled back, the links of our long history are never lost. As I went forward the vision of our own civilisation, in the form in which it finally found unity, grew clearer and clearer; nor did I ever know it more certainly than when I had left it behind.
