In examining the monument of New Grange, the author had been led by long study, and the comparison with motives common in the AEgean at about the same period, to explain the ornamentation, notably in the cases of the large stones illustrated in the book, p. 75, as derived from combinations of ornaments commonly found on AEgean pottery, these motives being themselves connected with the symbolism of sun-worship. In the case of other markings, it was considered these were possibly derived from the decoration of certain objects of Scandinavian origin. In an article in _L'Anthropologie_, vol. xxiii, p. 29, dealing with the subject, M. J. Dechelette has put forward other views with regard to the markings at New Grange. M. Dechelette sees in the markings at New Grange a degenerated copy of the female idols of neolithic times, carvings of which in a more or less rudimentary form have been found in the Iberian peninsula, Italy, France, England, and Scandinavia. It may be mentioned that from the occurrence of carvings of this idol on sepulchral monuments it is to be connected with funeral rites. M. Dechelette supports his contentions with a wealth of illustrations drawn from the tattooed idols of Greece, Portugal, and Aveyron, the engraved chalk cylinder from Madrid, the incised lines from Almizaraque, the sculptures from the artificial grottos of Marne, the vase fragments of Charantaise, the chalk drum from Folkton Wold (Yorkshire), and the engravings from the dolmens of Locmariaquer. On p. 43 M. Dechelette gives a scheme of the evolution of the pattern of the idol, starting from fairly well-defined eyes, eyebrows, and nose, with chevron marks imitating tattooing. The face becomes stylized by the substitution of a mere arched line for the eyebrows, and concentric circles for the eyes, the tattooing marks becoming a conventional pattern of regular chevrons. In the Irish examples the spiral replaces the concentric circles for the eyes, and the pattern below is further enriched by lozenges, and finally we arrive at a form in which the spiral has an eyebrow above and a single lozenge below, and this form M. Dechelette compares to the engravings on the slabs at New Grange. The shield-like figure on the roofing stone of the right recess at New Grange is compared by M. Dechelette to the engravings on the dolmen of Pierres-Plates at Locmariaquer, which also appear to be a stylized form of the idol. M. Dechelette compares the very remarkable boundary-stone at Dowth, with the engraving of suns on it, to the vases from Millares, province d'Almerie, which are ornamented with raised circles, these in their turn being derived from a degenerate form of the idol. M. Dechelette applies the same explanation to the scribings at Gavir'inis, the spiral ornamentation of which is to be regarded as derived from Ireland.
