Here he trafficked with the people, the first he had met, except the Finn hunters, since leaving his fiord. Besides his wish to see the country, he was looking for walrus-ivory and hides.
The Finns and Biarma-men (men of Archangel), it seemed to him, spoke nearly the same language, but between his home and this Biarmaland no human being lived in any fixed dwelling, and all the Northman's land was long and narrow and thinly peopled, decreasing in breadth as it stretched northward, from sixty to three days' journey.
Again Alfred told how Ohthere, sailing south for a month from his house, having Ireland on his right and coasting Norway all the time on his left, came to Jutland, "where a great sea runs up into the land, so vast that no man can see across it," whence in five days more he reached the coast, "from which the English came to Britain."
Wulfstan, in the service of the same king, told him how he sailed in seven days from Sleswick to Truso and the Vistula, having Wendland (or Pomerania and Prussia) on his right all the way. He described "Witland near the Vistula and Estland and Wendland and Estmere and the Ilfing running from the Truso lake into Eastmere," but neither the king nor his captains knew enough to contradict the old idea, found in Ptolemy and Strabo, of Scandinavia as one vast island.
Thus it was for the satisfaction of their Saxon Lord that Wulfstan and Ohthere, by their voyages along the coasts of Norway and Lapland, of Pomerania and Prussia, round the White Sea and the Gulf of Riga and southern Finland, added a more coherent view of north-east Europe, and specially of the Baltic Gulf, to Western geography; but these Norse discoveries, though in the service of an English king, were scarcely used save by Norsemen, and they must partly go to the credit of Vikings, as well as of Alfred the Great. Thus in 965 King Harold Grayskin of Norway "went and fought with the folk on the banks of the Dwina," and plundered them, and in 1026 Thorer Hund joined himself to a fleet sent by St. Olaf to the White Sea, pillaged the temple of the idol Jomala, and destroyed his countrymen by treachery on their way home. Where two expeditions are recorded they may well stand for twenty unknown and uneventful ones, and the same must be equally granted as to the gradual advance of knowledge through the unceasing attacks of the Norse kings and pirates on the lands to the south of the Baltic, where lived the Wends.
Thus on the west and east, north-west and north-east, the Northmen could and did make a definite advance into the unknown; even the south-west lines of Northern invasion and settlement, though they hardly yield any general results to discovery, certainly led to a more thorough inclusion of every part of the British isles in the civilised West, through the Viking earldoms in Caithness, in the Orkneys and the Shetlands, in Man and the Hebrides, and on the coast of Ireland, where the Ostman colonies grew into kingdoms. From about 840, when the first of these settlements was fairly and permanently started, to the eleventh century, when a series of great defeats,—by Brian Boru at Clontarf in 1014, by Godwine and Harold in England from 1042 to 1066, and by the Norman and Scottish kings in the next generation,—practically destroyed the Norse dominion outside the Orkneys,—for those two hundred years, Danes and Northmen not only pillaged and colonised, but ruled and reorganised a good half of the British isles.
By the time of Alfred the Viking principalities were scattered up and down the northern and western coasts of the greater of our two islands, and were fringing three sides of the lesser. About a.d. 900 the pioneer of the Norse kings, Harold Fair-hair, pursued his traitors, first to Shetlands and Orkneys, then to Caithness, the Hebrides, and Man. His son Eric, who followed him, ranged the Northern seas from Archangel to Bordeaux, and so Hakon the Good in 936 and other Norse princes in 946, 961, 965, above all, the two great Kings Olaf in 985-9 and 1009-14, fought and triumphed through most of the world as known to the Northmen. Thus, Frankland, England, Ireland, Scotland were brought into a closer unity through the common danger, while as the sea-kings founded settled states, and these grew by alliance, first with one another and then with their older Christian victims, as the Norse kingdoms themselves became parts of Latin Christendom, after Latin Christendom had itself been revived and re-awakened by their attacks, the full value of the time of trial came out on both sides, to conquered and to conquerors.
For the effects—formative, invigorative, provocative,—of the Northern invasions had a most direct bearing on the expansion that was to come in the next age even for those staid and sober Western countries, England and France and Italy, which had long passed through their time of migration, and where the Vikings could not, as in the far north-east and north-west, extend the area of civilisation or geographical knowledge.
Lastly, the new start made by England in exploration, and trade, and even in pilgrimage, is plainly the result—in action and reaction—of the Norse and Danish attacks, waking up the old spirit of a kindred race, of elder cousins that had sunk into lethargy and forgotten their seamanship.
But from the Peace of Wedmore (878) Alfred first of all began to build an English navy able to meet and chase and run down the Viking keels; then established a yearly pilgrimage and alms-giving at the Threshold of the Apostles in Rome; then sent out various captains in his service to explore as much of the world as was practicable for his new description of Europe. His crowning effort in religious extension was in 883, when Sigehelm and Athelstan bore Alfred's gifts and letters to Jerusalem and to India, to the Christians of San Thomé; the corresponding triumph of the King's scientific exploration, the discoveries in the White Sea and the Baltic, seem to have happened nearer the end of the reign, somewhere before 895.
