the Tiber alike flow into the Mediterranean; so did the Egyptian and the Etrurian alike contribute to a Mediterranean civilisation. The glamour of the great sea spread indeed very far inland, and the unity was felt among the Arabs alone in the deserts and the Gauls beyond the northern hills. But the gradual building up of a common culture running round all the coasts of this inner sea is the main business of antiquity. As will be seen, it was sometimes a bad business as well as a good business. In that orbis terrarum or circle of lands there were the extremes of evil and of piety, there were contrasted races and still more contrasted religions. It was the scene of an endless struggle between Asia and Europe from the flight of the Persian ships at Salamis to the flight of the Turkish ships at Lepanto. It was the scene, as will be more especially suggested later, of a supreme spiritual struggle between the two types of paganism, confronting each other in the Latin and the Phoenician cities; in the Roman forum and the Punic mart. It was the world of war and peace, the world of good and evil, the world of all that matters most; with all respect to the Aztecs and the Mongols of the Far East, they did not matter as the Mediterranean tradition mattered and still matters. Between it and the Far East there were, of course, interesting cults and conquests of various kinds, more or less in touch with it, and in proportion as they were so intelligible also to us. The Persians came riding in to make an end of Babylon; and we are told in a Greek story how these barbarians learned to draw the bow and tell the truth. Alexander the great Greek marched with his Macedonians into the sunrise, and brought back strange birds coloured like the sunrise clouds and strange flowers and jewels from the gardens and treasuries of nameless kings. Islam went eastward into that world and made it partly imaginable to us; precisely because Islam itself was born in that circle of lands that fringed our own ancient and ancestral sea. In the Middle Ages the empire of the Moguls increased its majesty without losing its mystery; the Tartars conquered China and the Chinese apparently took very little notice of them. All these things are interesting in themselves;
