Only one other group need be mentioned here. On a spot of land, in the island of Freyrsö, off the entrance of the Drontheim Fiord, in the year 958, Hakon, the son of Harald Harfagar, overthrew his nephews, the sons of Erik Blodoxe, in three battles. The first and second of these, as shown in the plan (woodcut No. 104), are marked by cairns and mounds; and the third by eight large barrows, three of which are of that shape known in Scandinavia as ship barrows, and measure from 100 to 140 feet in length. There are also three tumuli at 4 in the woodcut, in one of which one of Erik Blodoxe's sons is said to be buried. It is not clear whether the five large mounds that stud the plain do not cover the remains of those also who fell in this fight. It does not appear that any excavations have been made in them. The interest of this battle-field to us is not so much because it shows the persistence of this plan of marking battle-fields at so late a date--later ones have just been quoted--but because all the actors in the scene are familiar to us from the part they took in the transactions in the Orkneys in the tenth century. If they, in their own country, adhered to these old-world practices, we should not be astonished at their having erected circles or buried in mounds in their new possessions. It is true that none of these Scandinavian circles can compare in extent with the Standing Stones of Stennis or the Ring of Brogar, but this would not be the first time that such a thing has happened. The Greeks erected larger and, in proportion to the population, more numerous Doric temples in Sicily than they possessed in their own country; and the Northmen may have done the same thing in Orcadia, where they possessed a conquered, probably an enslaved, race to execute these works.
