How near, to "speak as a fool," the plans of God came to being defeated by human enterprise is illustrated by unquestioned facts. The fact of medieval exploration, colonization, and even evangelization in North America seems now to have emerged from the region of fanciful conjecture into that of history. That for four centuries, ending with the fifteenth, the church of Iceland maintained its bishops and other missionaries and built its churches and monasteries on the frozen coast of Greenland is abundantly proved by documents and monuments. Dim but seemingly unmistakable traces are now discovered of enterprises, not only of exploration and trade, but also of evangelization, reaching along the mainland southward to the shores of New England. There are vague indications that these beginnings of Christian civilization were extinguished, as in so many later instances, by savage massacre. With impressive coincidence, the latest vestige of this primeval American Christianity fades out in the very year of the discovery of America by Columbus.
