The question, why did such-and-such nations take to the sea and why for so long a time, and then again abandon it for so long a time, I can answer in no other way.
It is a beckoning from powers outside mankind.
It is not even the establishment of commerce by sea which takes a people to sea. Nothing more likely than for a nation to become a nation of transport and yet to see its crews gradually becoming foreign, as its own people grew to dislike the nasty but mysteriously summoning business of wet decks and thumping. It certainly is not proximity to the sea that does the trick. You have all over the world great lumps of population, millions and millions, right on to the sea, who never take to it, but leave a fringe of foreigners to do their sailing. Witness the Slavs. And though, of course, it is true that inland nations are not seafaring nations, the real reason is much more that they choose to be inland than that they happen to be inland.
I have asked myself often enough why the old Egyptians did not take to the sea. Perhaps they did very long ago, but at any rate the memory of it has died out. The other people who traded with them from the North have not even legends of Egyptians coming to them. We have no stories or inscriptions of Egyptians common in the harbours of the Mediterranean. And yet they had a great river going straight out to sea and a coast that for thousands of years, in the height of their power, invited them. They had ships, no doubt, which were sea-going. We know of fleets, but we are not always certain that they were Egyptian fleets, even when they were fleets under the command of the Egyptian king. What we have not got is an Egyptian maritime legend or tradition.
On the other hand, you find an enormous, volcanic, seafaring energy just where it should not be—on the harbourless coast of the Levant. And it seems certain, to me reading, that those seafarers who kept it up for centuries, the people of Tyre and Sidon, were driven by masterful instinct. It seems possible or even probable that they started from some little islands in the Persian Gulf, and that, for some reason, they came all this way across desert land and began again from other little islands hundreds of miles away upon another sea. Once they had started from the Levantine coast they did everything that the sea makes one do. They explored, and they named. They must have felt the fun of the thing. Commerce can only have been their second motive, though naturally it is the motive we put first to-day.
A learned member of the University of Paris has shown that most of the inexplicable Greek names of the Mediterranean were but Phœnician names transformed, and they even went out of the tideless sea into the huge unknown swell of the ocean. And they reached, according to one story, those tin-mines which were either off the Spanish coast or in some part of Britain—perhaps Cornwall.
But remark that these people had everything against them. It is silly to say that they were driven to commerce by their geographical position between East and West. It was just the other way. Their geographical position was the worst possible. The splendid harbours which lay some days' sail to the west of them they knew nothing of. They were on a coast less suited for the shelter of vessels than any in the whole Mediterranean, unless it be the eastern coast of Barbary. They went to sea because a passion seized them for it, because it was in their blood.
I notice again that this passion for the sea does not go, as one would think it ought to, with a particular physical type, nor even with a particular mental type. It certainly goes with a love of adventure, but not with mere vigour, nor even with mere imagination. And the same race will appear, for generations, inhabited by this haunting of the sea, and then will suddenly drop it again.
This island is an example. It was seafaring all during the Roman centuries. Then after the robber raids of the Saxons, Angles, Irish, Frisians, Franks, and the rest, it lost all idea of the sea. When England had become a welter of little districts Pagan and Christian all fighting each other in the sixth and seventh centuries, England no longer went to sea. It got cut off; and when, a little later, seafaring men from Scandinavia attacked it, it could not defend itself. It lay passive. It was not till Alfred's time, more than four hundred years after the catastrophe of the first pirate raids in Britain, that there was something of a reluctant seafaring again; and even then it was for more than a hundred years easier to hire Scandinavian crews than to get Englishmen aboard.
But all this while the Irish and the people of the Far West, the Welsh, Southern and Northern, and the Cornish, were filling their legends with the sea.
