The truth of the matter seems to be that, as in the case of a find of coins, it is the date of the last piece that fixes the time of the deposit. There may be coins in it a hundred or a thousand years older, but this hoard cannot have been buried before the last piece which it contains was coined. So it is with this barrow. The presence of Roman or post-Roman pottery in an avowedly undisturbed sepulchre fixes, beyond doubt, the age before which the skeletons could not have been deposited where they were found by Dr. Thurnam. The presence of flints and coarse pottery only shows, but it does so most convincingly, how utterly groundless the data are on which antiquaries have hitherto fixed the age of these monuments. It proves certainly that flints and shards were deposited in tombs in Roman or post-Roman times; and if there is no mistake in Dr. Thurnam's data, this one excavation is, by itself, sufficient to prove that the Danish theory of the three ages is little better than the "baseless fabric" of--if not "a vision"--at least of an illusion, which, unless Dr. Thurnam's facts can be explained away, has no solid foundation to rest upon. If any systematic excavations had been undertaken in the Scandinavian long barrows, it would not, perhaps, be necessary to adduce English examples to illustrate their age or peculiarities. Several are adduced by Sjöborg, but none are reported as opened. This one, for instance, is externally like the long barrow at West Kennet, and, if Sjöborg's information is to be depended upon, is one of several which mark the spot where Frode V. (460-494) landed in Sweden, where a battle was fought, and those who fell in it were buried in these mounds, or where the Bauta stones mark their graves. If this is so, the form of the long barrow with its peristalith was certainly not unknown in the fifth century; and there is no improbability of its being employed in England also in that age. In settling these questions, however, the Scandinavians have an immense advantage over us. All their mounds have names and dates; they may be true or they may be false, but they give a starting-point and an interest to the enquiry which are wanting in this country, but which, it is hoped, will one day enable the Northmen to reconstruct their monumental history on a satisfactory basis.
