“There exist several explanations on the subject, M. Aronnax. Would you like to know the opinion of a chronicler of the fourteenth century?”

“Willingly.”

“This fanciful writer pretends that its name was given to it after the passage of the Israelites, when Pharaoh perished in the waves which closed at the voice of Moses.”

“A poet’s explanation, Captain Nemo,” I replied; “but I cannot content myself with that. I ask you for your personal opinion.”

“Here it is, M. Aronnax. According to my idea, we must see in this appellation of the Red Sea a translation of the Hebrew word ‘Edom’; and if the ancients gave it that name, it was on account of the particular colour of its waters.”

“But up to this time I have seen nothing but transparent waves and without any particular colour.”

“Very likely; but as we advance to the bottom of the gulf, you will see this singular appearance. I remember seeing the Bay of Tor entirely red, like a sea of blood.”

“And you attribute this colour to the presence of a microscopic seaweed?”

“Yes.”

“So, Captain Nemo, it is not the first time you have overrun the Red Sea on board the Nautilus?”

“No, sir.”

“As you spoke a while ago of the passage of the Israelites and of the catastrophe to the Egyptians, I will ask whether you have met with the traces under the water of this great historical fact?”

“No, sir; and for a good reason.”

“What is it?”

“It is that the spot where Moses and his people passed is now so blocked up with sand that the camels can barely bathe their legs there. You can well understand that there would not be water enough for my Nautilus.”

“And the spot?” I asked.

“The spot is situated a little above the Isthmus of Suez, in the arm which formerly made a deep estuary, when the Red Sea extended to the Salt Lakes. Now, whether this passage were miraculous or not, the Israelites, nevertheless, crossed there to reach the Promised Land, and Pharaoh’s army perished precisely on that spot; and I think that excavations made in the middle of the sand would bring to light a large number of arms and instruments of Egyptian origin.”

“That is evident,” I replied; “and for the sake of archaeologists let us hope that these excavations will be made sooner or later, when new towns are established on the isthmus, after the construction of the Suez Canal; a canal, however, very useless to a vessel like the Nautilus.”

“Very likely; but useful to the whole world,” said Captain Nemo. “The ancients well understood the utility of a communication between the Red Sea and the Mediterranean for their commercial affairs: but they did not think of digging a canal direct, and took the Nile as an intermediate. Very probably the canal which united the Nile to the Red Sea was begun by Sesostris, if we may believe tradition. One thing is certain, that in the year 615 before Jesus Christ, Necos undertook the works of an alimentary canal to the waters of the Nile across the plain of Egypt, looking towards Arabia. It took four days to go up this canal, and it was so wide that two triremes could go abreast. It was carried on by Darius, the son of Hystaspes, and probably finished by Ptolemy II. Strabo saw it navigated: but its decline from the point of departure, near Bubastes, to the Red Sea was so slight that it was only navigable for a few months in the year. This canal answered all commercial purposes to the age of Antonius, when it was abandoned and blocked up with sand. Restored by order of the Caliph Omar, it was definitely destroyed in 761 or 762 by Caliph Al-Mansor, who wished to prevent the arrival of provisions to Mohammed-ben-Abdallah, who had revolted against him. During the expedition into Egypt, your General Bonaparte discovered traces of the works in the Desert of Suez; and, surprised by the tide, he nearly perished before regaining Hadjaroth, at the very place where Moses had encamped three thousand years before him.”
