The ornaments which cover the walls of the chambers at New Grange are very varied, both in their form and character. The most prevalent design is that of spirals variously combined, and often of great beauty. They seem always to have been drawn by the hand, never outlined with an instrument, and never quite regular either in their form or combination. The preceding woodcuts from rubbings give a fair idea of their general appearance, though many are much more complex, and some more carefully cut. The most extensive, and perhaps also the most beautiful, is that on the external doorstep.[248] These spirals are, however, seldom alone, but more frequently are found combined with zigzag ornaments, as in (woodcut No. 66), and in lozenge-shaped patterns; in fact, in every conceivable variety that seemed to suit the fancy of the artist, or the shape of the stone he was employed upon. In one instance a vegetable form certainly was intended. There may be others, but this one most undoubtedly represents either a palm branch or a fern; my impression is that it is the former, though how a knowledge of the Eastern plant reached New Grange is by no means clear. One other example of the sculptures is worth quoting, if not for its beauty, at least for its interest (woodcut No. 68). It is drawn full size in the second volume of the 'Archæologia,' p. 238, and Governor Pownall, after a learned disquisition, concludes that the characters are Phœnician but only numerals (p. 259). General Vallancey and others have not been so modest; but one thing seems quite clear, that it is not a character in any alphabet now known. Still it can hardly be a mere ornament. It must be either a mason's mark, or a recognizable symbol of some sort, something to mark the position of the stone on which it is engraved, or its ownership by some person. Similar marks are found in France, but seem there equally devoid of any recognizable meaning. [Illustration: 69. Chambers in Mound at Dowth. From a MS. plan.]
