Very few of the _old_ Northern letters are found. The "Dragon" and "Worm Knot" are still perfectly distinct, and have evidently been carved by superior artists. With the exception of two stones--one of which is shewn in the drawing of the interior of the tumulus, and on which four letters are carved--none have been found bearing any inscription amongst the debris, nor is there any reason to suppose that stones bearing inscriptions have been removed from the walls. The two stones before alluded to had evidently been used to close up the cells, and lay on the basement floor just below the entrances to the cells from which they had been rudely torn. In one of the cells, that on the left side of the chamber, a few letters were indistinctly written. By accident they were forgotten, and no casts were taken of them. It is not easy to account for the various elevations at which the carvings were made. Those on the higher parts could not have been reached by persons standing at the bottom, but they might have been inscribed after the roof had been broken in, and when the building was in a partially ruined state. Many of the marks, possibly some of the "scratches" or "scribbles" to which no importance is attached, and perhaps even some of the doubtful letters, may be the result of violence used in breaking in the roof. Most of the Runes belong to the Norwegian division of the Scandinavian class, and have nothing to do with the Gothic or older alphabet, but, in the opinion of Professor Munch, they exhibit some archaicisms which prevent their being placed in the latest times of the Norwegian class; they must therefore be referred to about A. D. 1150. [Sidenote: _Date of Inscriptions._] The meaning of the word Maes-Howe is very obscure. It is, as Professor Munch remarks, not easy to explain. The haugr, pronounced how, is plain enough; the word Maes might have been derived from Meitis, pronounced almost like Meiss, Meitir, gen. Meiris, which was the name of a fabulous sea king, and was afterwards used to denominate any mighty king or warrior. Meiris-haugr therefore might have been synonymous with the how, or tumulus of this fabulous sea king. This opinion of Professor Munch's is at all events not unlikely to be correct; certainly local tradition has always ascribed a sepulchral character to the mound. Professor Rafn thinks that the word is derived from Mar,[3] the name of a man, and that valuable information might be obtained if it were found possible to read with a greater degree of accuracy the Runes Nos. 6 and 7, since Orki and Mar are named in these inscriptions, and it is to be inferred that Mar Orkason had engraved some of these Runes.
