From the narrative of a voyage north of Baffin’s Bay, about the year 1267, it appears that they endeavoured at sea to get an idea of the sun’s altitude by observing where the shadow of the gunwale, on the side nearest the sun, fell on a man lying athwartships when the sun was in the south. This shows, at any rate, that the Norsemen did at least observe the sun’s altitude. Even in thick weather they could get along satisfactorily provided that the wind did not shift and send them off their course. But if the breeze veered or backed a few points they would be heading unconsciously in the wrong direction.
The observations of birds were of no little assistance. If the haze hid the land off whose coasts they imagined themselves to be, they could observe the kind of bird which was flying around them. A flight of wild-fowl, a particular breed of sea-bird, the difference in the fauna, and so on, when off such coasts as Scotland, Ireland, Iceland, and Norway, could not fail to assist them greatly. It is true, also, that in their sailing directions they took notice of the whale. Thus, when sailing from Norway to Greenland one should keep at such a distance to the southward of Iceland as to have birds and whales from thence. Similarly, the drift-ice, icebergs, driftwood, floating seaweed, the colour of the sea were all separate units in the whole method which enabled them to perform what they did. The Gulf Stream water, being of a purer blue than the greenish-brown water of the coastal current, must also have assisted them in their long voyages. Like the ancient seamen of the Mediterranean, they relied largely on the sounding lead, and there is a record that Ingolf and Hjorleif found Iceland “by probing the waves with the lead.”
Primitive Navigation of the Vikings.
Finding the ship’s latitude by the shadow of the gunwale.
As to the primitive method, referred to above, for finding the ship’s latitude by observing the shadow of the gunwale, it has been suggested that they might have measured the length of the shadow of the gunwale by marks on the thwart, and determined when the boat lay on an even keel by means of a bowl of water. They could thus obtain a fairly trustworthy measurement of the sun’s altitude. It has been thought possible that the Norwegians might have become acquainted with the hour-glass either from their voyages to Southern Europe, or else by plundering the monasteries. This would enable them to measure the length of day approximately, and so, taken in conjunction with the sun, be able to tell fairly correctly the direction of the cardinal points of the compass.
There are some who scoff at the idea that the Vikings discovered North America. But there are first-rate authorities, among whom may be reckoned Dr. Nansen himself, who are quite convinced that these men did sail across the sea and land there. Certain incredulous people would have us believe that an open craft such as the Viking type would never last out a voyage like that across the Atlantic. But this supposition is immediately refuted by the Norse craft which was built on the lines and to the exact dimensions of the Gogstad Viking ship discovered in 1880. Rigged with a squaresail, with a jib added and without any other ship as convoy, this replica was sailed from Bergen to Newport, Rhode Island, in the year 1893. The voyage began on May 1, and the United States were reached on June 13. She was commanded by Captain Magnus Andersen, who had already, in 1886, crossed the Atlantic in an open boat. Although bad weather was encountered, yet Captain Andersen and his crew of eleven men reached Newport in safety. His ship proved that the Viking type made a very fine seaboat, and furthermore that she was fast even in the deep furrows of the ocean; for she did an average of nine knots easily, but when the seas fitted her exactly she could reel off her eleven knots.
For these old Vikings, intrepid mariners and pioneers of the sea, had by their skill and experience been able to develop an improved type of ship which combined the advantages of speed and seaworthiness. In such craft they voyaged to places as far apart as Palestine and Greenland. By their travels they completely changed the existing ideas of geography. When they ceased to make merely coasting voyages and took to the blue water, they were doing more than perhaps they realised. They crossed the North Sea to the Shetlands and Orkneys, to Britain and Ireland, to the Faroe Isles, to Iceland, to Greenland, and finally to America. Just exactly when first the Northmen crossed the North Sea cannot be determined; but some authorities believe that it was undertaken before the Viking age. As early as the third century of the Christian era, the Eruli sailed from Scandinavia over the seas of Western Europe and ravaged Gaul and Spain, and even penetrated during the fifth century to the Mediterranean as far as Italy. During the sixth century the Vikings voyaged from Denmark to the land of the Franks, but the first Viking expedition began in A.D. 793. In the year 999, Leif, the son of Eric the Red, sailed from Greenland via the Hebrides to Norway. This is the first recorded time that such a lengthy sea voyage was attempted, for prior to this the journey had been made via Iceland. But it is also clear, from the sailing directions which have come down to us for navigating the northern waters, that voyages were made direct from Norway to Greenland. It was this same Leif who, in the year A.D. 1000, discovered America.
The question must necessarily occur (as in the case of the circumnavigation of Africa by the Phœnicians) as to the means of provisioning these Viking ships for such lengthy cruises. If Captain Andersen and his men in 1893 were able to last out, there is no reason why the ancient Norsemen should not, even if we make some allowance for the modern advantages of preserved foods. We know very little as to the methods adopted to ensure adequate food-supplies, but we do know that bronze cooking vessels have been found which belonged to these craft. They used salt meat and salt fish, and these they could obtain by hunting and fishing in the neighbourhood of Iceland, Scotland, Greenland, and so on. Nansen asserts that they certainly took cattle with them on some voyages; and they could also catch seals to keep the pot from running empty. In sheltered waters, such as the Norwegian fjords, when at anchor, the crew erected a triangular awning over the ship and turned-in in leather sleeping bags.
But it is by making a careful study of the Sagas that we are able to get a true idea of the life and methods of these magnificent seamen, and from this source I propose to extract the following interesting data. In these heroic narratives there is much to interest the lover of the sea and ships. There is a continual clashing of shield and sword, a slatting of canvas and a splashing of oars, as the long-ships leap over the cold, silvery seas. The air is full of the deep-throated shouts of the sea-kings; the horizon is bright with the coloured sails and the gilded prows. Every man is a picked fighter and seaman; every craft a thing of beauty and of strength. There are the dark, cruel rocks, and the crimson blood of the vanquished, the sound of the waterfalls coming down from the cliffs, the fluttering of pennants, the hammering of the shipwrights’ men ashore, the cries of the women-folk as they behold the distant battles. There is nothing subtle in the picture; the colours are laid thickly, and the tones are crude as a modern poster. But there is bravery and seamanship, and above all the sweet sea smell which pervades these accounts and stirs the enthusiasm of the reader to its full extent. You feel as you read them that ships and men both seem to have been of the right stuff, that in those days there was a grandeur about the sea which not easily can be forgotten.
