The Arabian Edrisi portrays it under the name of the Gulf of Colzoum, and relates that vessels perished there in great numbers on the sandbanks and that no one would risk sailing in the night. It is, he pretends, a sea subject to fearful hurricanes, strewn with inhospitable islands, and ‘which offers nothing good either on its surface or in its depths.’” “One may see,” I replied, “that these historians never sailed on board the Nautilus.” “Just so,” replied the Captain, smiling; “and in that respect moderns are not more advanced than the ancients. It required many ages to find out the mechanical power of steam. Who knows if, in another hundred years, we may not see a second Nautilus? Progress is slow, M. Aronnax.” “It is true,” I answered; “your boat is at least a century before its time, perhaps an era. What a misfortune that the secret of such an invention should die with its inventor!” Captain Nemo did not reply. After some minutes’ silence he continued: “You were speaking of the opinions of ancient historians upon the dangerous navigation of the Red Sea.” “It is true,” said I; “but were not their fears exaggerated?” “Yes and no, M. Aronnax,” replied Captain Nemo, who seemed to know the Red Sea by heart. “That which is no longer dangerous for a modern vessel, well rigged, strongly built, and master of its own course, thanks to obedient steam, offered all sorts of perils to the ships of the ancients.
