between the mounds at Jellinge and Stennis and those on the Boyne than has been accorded above; and as it seems equally difficult to bring them nearer to one another, the probability seems to be in favour of the dates already assigned to them. To return, however, from this digression; besides those just mentioned, Denmark possesses a nearly complete series of royal tombs such as are not to be found in any other country of Europe. Even Worsaae acknowledges the existence of that of Frode Frodegode, who lived about the Christian era, of Amlech, near Wexio--Shakespeare's Hamlet, of Humble, and Hjarne,[352] besides those of Hildetand, and Gorm and Thyra, already mentioned. If the Danes would only undertake a systematic examination of these royal sepulchres, it might settle many of the disputed points of mediæval archæology. To explore tombs to which no tradition attaches may add to the treasures of their museums, but can only by accident elucidate either the history of the country or the progress of its arts. If ten or twelve tombs with known names attached to them were opened, one of two things must happen: either they will show a succession and a progress relative to the age of their reputed occupants, or no such sequence will be traceable. In the first case the gain to history and archæology would be enormous, and it is an opportunity of settling disputed questions such as no other country affords. If, on the other hand, no such connection can be traced, there is an end of much of the foundations on which the reasoning of the previous pages is based, but in either case such an enquiry could not fail to throw a flood of light on the subject which we were trying to elucidate. The fear is that all have been rifled. The Northmen certainly spared none of the tombs in the countries they conquered, and our experience of Maes-Howe and Thyra's tomb would lead us to fear that after their conversion to Christianity they were as little inclined to spare those of their own ancestors. All they however cared for were the objects composed of precious metals; so enough may still be left for the less avaricious wants of the antiquary. DOLMENS.
