Good story -- unhackneyed background -- and this particular pair of authors can be counted on for sound scholarship and excellent handling of their material. A story of the northlands, of a son of a yarl of Norway, destined to rule, and condemned instead to slavery in the hands of German savages, a galley slave, cowed and beaten and held captive during many years. Finally he escapes to Constantinople -- there grows soft in luxury -- and finally is roused to action by the blind harper who has sought him over Europe. They return, to find that Christian leaders of Norway have been driven forth and heathen reinstated. They follow their people -- and the sign of the White Christ, to a new land, first the New World, then Greenland, where they settle.
