"The number of tombs of the bronze epoch which have been discovered in Denmark is very considerable. There are thousands of _tumuli_, and many of them contain a large number of funeral urns. A great many of these _tumuli_ have been searched at various times and have produced a number of different bronze articles. The Museum of Copenhagen possesses no less than 600 swords dating back to the bronze epoch."[38] Twenty years ago, however, a very curious discovery was made at Lübeck (Pomerania), for it exhibited, so to speak, in the same tomb, the three modes of interment belonging to the pre-historic epochs of the stone, bronze, and iron ages. At Waldhausen, near Lübeck, a _tumulus_ was found, which was 13 feet 9 inches in height. This _tumulus_ was pulled down in horizontal layers, and the following details were successively brought to light. At the top was a very ancient burial-place, evidently belonging to the iron age; for the skeleton it contained was accompanied by an object made of rusty iron and several earthenware articles. It was buried in loose earth. Underneath this, and half way down the _tumulus_, there were some small enclosures composed of uncemented walls, each one containing a sepulchral urn filled with calcined bones, as well as necklaces, hair-pins, and a bronze knife. Lastly, at the base of the _tumulus_, there was a tomb belonging to the Stone Age. It was formed of large rough blocks of stone, and contained, in addition to the bones, some coarse specimens of pottery, with flint hatchets. It is evident that the first inhabitants of the country began by building a tomb on the bare ground, according to the customs of the age, and then covered it up with earth. During the bronze epoch another burial-place was made on this foundation, and a fresh heap of earth doubled the height of the mound. Lastly, during the iron age, a dead body was buried in a grave hollowed out on the top of the same mound. Here, then, we have a clear delineation of the three different modes of interment belonging to the three pre-historic periods. In short, during the bronze epoch, the dead were generally buried in sepulchral chambers, and sometimes, exceptionally, they were burned. The custom of funeral feasts still remained in full force. The pious practice of placing by the side of the dead body the instruments or weapons which the individual had been fond of during his lifetime, was likewise still kept up; and it is, moreover, owing to this circumstance that archæological science is now enabled to collect numerous vestiges of the ancient customs of these remote ages.
