The extract given above from the old writer impresses on us a fact we must bear well in mind, namely, that the Baltic mainland littoral at the time the Teutonic merchants began to ply their trade upon its coast was not a German possession, but inhabited and owned by a Slavonic people, who clung to their pagan creed long after their neighbours in the East and West had become converted to the new religion. And, as usual to this day, it was the trader who preceded the missionary, and gave the natives the first idea of a different code of ethics and morality. In the missionary's track, as at this day, followed the soldier, enforcing by the sword the arguments that reason had failed to inculcate. It was thus that German merchants had founded on Slavonic soil the various cities and ports that were later to be the pride and strength of the Hanseatic Union. Nor did they rest content with the coast that bounded their own lands. They traversed the narrow ocean, touching Finland, Sweden, and Russia, and they established on the isle of Gothland an emporium, which, in the first Christian centuries, became the centre of the Baltic trade, and in which "people of divers tongues," as an old writer calls these visitors, met to exchange their products. A glance at the map will show why this island assumed such importance. At a time when the mariner was restricted to short passages, not liking for long to lose sight of the shore, this spot naturally made a most favourable halting-place on the road to Finland, Livonia, or Sweden. It is evident from the chronicles that the Germans soon acquired and exercised great power in this island, and that they were accorded special privileges. Thus Pope Honorius II. granted them his protection for their town and harbour of Wisby, in acknowledgment of the part they had played in the conversion of the pagan nations. There are many testimonies to the ancient wealth and commercial importance of the island of Gothland; among them the amount of Roman, Byzantine, Anglo-Saxon, and German coins still found on its soil, as also the number of ruined churches, many of them of great size and architectural beauty, dotted over its area. To this day the island, impoverished and depopulated, owns a church to every six hundred inhabitants. The churches have fallen into sad decay, but yet remain to testify of past prosperity and glory.
