On all the coast, the pirates stood in awe only of the navigators from the Marina, so fearless and warlike were they. If their villages were ever attacked, it was because their seafaring defenders were on the Mediterranean and, in their turn, had gone to sack and burn some village on the coast of Africa.

The Triton and his nephew used to eat their supper under the arbor in the long summer twilights. After the cloth was removed Ulysses would manipulate his grandfather's little frigates, learning the technical parts and names of the different apparatus, and the management of the sets of sails. Sometimes the two would stay out on the rustic porch until a late hour gazing out over the luminous sea sparkling under the splendor of the moon, or streaked with a slender wake of starry light in the murky nights.

All that mankind had ever written or dreamed about the Mediterranean, the doctor had in his library and could repeat to his eager little listener. In Ferragut's estimation the mare nostrum ["Mare Nostrum" (Our Sea), the classic name for the Mediterranean.] was a species of blue beast, powerful and of great intelligence—a sacred animal like the dragons and serpents that certain religions adored, believing them to be the source of life. The rivers that threw themselves impetuously into its bosom in order to renew it were few and scanty. The Rhone and the Nile appeared to be pitiful little rivulets compared with the river courses of other continents that empty into the oceans.

Losing by evaporation three times more liquid than the rivers bring to it, this sunburnt sea would soon have been converted into a great salt desert were not the Atlantic sending it a rapid current of renewal that was precipitated through the Straits of Gibraltar. Under this superficial current existed still another, flowing in an opposite direction, that returned a part of the Mediterranean to the ocean, because the Mediterranean waters were more salt and dense than those of the Atlantic. The tide scarcely made itself felt on its strands. Its basin was mined by subterranean fires that were always seeking extraordinary outlets through Vesuvius and Aetna and breathed continually through the mouth of Stromboli. Sometimes these Plutonic ebullitions would come to the surface, making new islands rise up upon the waters like tumors of lava.

In its bosom exist still double the quantity of animal species that abound in other seas, although less numerous. The tunny fish, playful lambs of the blue pasture lands, were gamboling over its surface or passing in schools under the furrows of the waves. Men were setting netted traps for them along the coasts of Spain and France, in Sardinia, the Straits of Messina and the waters of the Adriatic. But this wholesale slaughter scarcely lessened the compact, fishy squadrons. After wandering through the windings of the Grecian Archipelago, they passed the Dardanelles and the Bosphorus, stirring the two narrow passageways with the violence of their invisible gallopade and making a turn at the bowl of the Black Sea, swimming back, decimated but impetuous, to the depths of the Mediterranean.

Red coral was forming immovable groves on the substrata of the Balearic Islands, and on the coasts of Naples and Africa. Ambergris was constantly being found on the steep shores of Sicily. Sponges were growing in the tranquil waters in the shadow of the great rocks of Mallorca and the Isles of Greece. Naked men without any equipment whatever, holding their breath, were still descending to the bottom as in primitive times, in order to snatch these treasures away.

The doctor gave up his geographic descriptions to discourse on the history of his sea, which had indeed been the history of civilization, and was more fascinating to him. At first miserable and scanty tribes had wandered along its coasts seeking their food from the crustaceans drawn from the waves—a life similar to that of the rudimentary people that Ferragut had seen in the islands of the Pacific. When stone saws had hollowed out the trunks of trees and human arms had ventured to spread the first rawhides to the forces of the atmosphere, the coasts became rapidly populated.

Temples were constructed on the promontories, and maritime cities—the first nuclei of modern civilization—came into existence. On this landlocked sea mankind had learned the art of navigation. Every one looked at the waves before looking at the sky. Over this blue highway had arrived the miracles of life, and out of its depths the gods were born. The Phoenicians—Jews, become navigators—abandoned their cities in the depths of the Mediterranean sack, in order to spread the mysterious knowledge of Egypt and the Asiatic monarchies all along the shores of the interior sea. Afterwards the Greeks of the maritime republics took their places.

In Ferragut's estimation the greatest honor to which Athens could lay claim was that she had been a democracy of sailors, her freemen serving their country as rowers and all her famous men as great marine officials.

"Themistocles and Pericles," he added, "were admirals of fleets, and after commanding ships, governed their country."
