Under all human conditions it is necessary that some method should be adopted for the disposal of the dead; but there can be no doubt that the religious sentiment has ever been the predominating factor in all burial customs. The earliest method of disposing of the dead was by simple interment; and even when cremation became general, the practice was never entirely abandoned. Both forms may occur in the same mound; but the general result is that the inhumed remains are found at the bottom, and the cremated remains nearer the surface, which shows these were later in point of time. Where, however, the earliest interments have been burnt bones, inhumed bodies, as at Ballon Hill, may form secondary burials. The result of Canon Greenwell’s explorations in the barrows of Yorkshire showed that out of 379 burials 301 were by inhumation, and in 78 cremated remains were found. Exploration in other parts of England gave similar results.[57] Out of 297 interments in Derby, Stafford, and York, Mr. Bateman found that 124 were of burnt bones; 163 were of ordinary burials, of which latter the bodies in 97 had been placed in a contracted or sitting position. Sir R. C. Hoare found that out of 267 interments in Wiltshire, 214 were of cremated remains, 53 of inhumed, of which the skeletons of 15 were found contracted. In the district of Glasinac is a vast collection of tumuli. ‘Their total number,’ says Dr. Munro, ‘is estimated at 20,000--an estimation which is now regarded as coming far short of the actual number--of which about 1000 have been explored.... The builders of these burial mounds practised both inhumation and cremation, the former being in the proportion of 60 per cent., and the latter 30 per cent., while the remaining 10 per cent. were of a mixed character, _i.e._, contained both kinds of interments.’[58] In the Hallstatt cemetery in the Noric Alps (which has given its name as a distinctive term to an archæological period, owing to the importance of its ‘grave-goods’), tombs to the number of 993 were examined as far back as 1868. Of these ‘525 contained simple interments; 455 had incinerated human remains; and in 13 the bodies had only been partially burnt before being interred.’[59] Great quantities of implements, domestic articles, and objects for personal use and adornment have been found in both classes of graves.
