Yet to him who has preserved some shreds of his classical learning, the passage from the Atlantic to the Mediterranean has a still deeper significance. It marks the separation of the old and the new worlds. At the Pillars of Hercules the old world ended; they guarded the threshold of the unknown. On the inland sea within were cradled the civilizations on which our own is mainly based—Hebrew, Hellenic, Roman. Perhaps we may wonder at their limitations, especially at the comparative inefficiency of Rome in maritime affairs. If Rome with her vast resources had owned a spark of the naval enterprise of ancient Phœnicia or modern Britain; if she had spent on the sea a tithe of the energy she exercised on land— exhibited nowhere more completely than in that Northern Africa to which we are bound—the history of the world might, indeed, have taken a different course. But it was reserved for the great awakening of the fifteenth century to probe the secrets of the mysterious Atlantic, and to throw open vast fields for conquest and colonization to the European races. And when through the gathering darkness we look back to the twin peaks, we recall the legend of the two dragons guarding the entrance to the Garden of the Hesperides, and wonder if it was invented by ancient mariners to cover their lack of enterprise. Many Mediterranean cities present a fair prospect to him who comes by sea, especially in the pearly radiance of the Mediterranean dawn. Algiers surpasses all. The steepness of the hill-side which it fills and its own white brilliancy give to it a special distinction. Many writers, following a leader as sheep that have gone astray, have compared it to the tiers of seats rising one above another in a Greek theatre—a fanciful and baseless comparison. There is no such ordered arrangement. The straight lines of modern houses enclose a central mass of strange irregularity, so confused that from a distance it has the semblance of a heap of ruins. This is the remnant of the Arab city, a swarming ant-heap of native life, filled with strange and savage memories of the astonishing pirates who were through centuries, and even until living memory, the scourge of Christendom. The sea front has entirely lost its ancient aspect; its long line of symmetrical houses, with its Boulevard de la République, and its Boulevard Carnot, recalls Palermo or Messina. And stretching south and east along the hills which encircle the bay the city’s suburbs seem to have no end; white houses gleam amid dark foliage and splendid villas crown the heights.
