A third barrow explored by the Rev. W. Stillingfleet also covered the skeleton of a warrior with the remains of his martial equipment, consisting of the bosses of his shield, one wheel of his chariot, two of his horses’ bridle-bits. Two wild boars’ tusks (one of which was perforated with a square hole, and enclosed in a case of thin brass) were associated with this burial; indicating, perhaps, some religious or superstitious belief connected with this animal.[112] [112] A Late-Celtic boar’s head of bronze was found at Liecheston, in Banffshire, in 1816 (see Dr. J. Anderson’s _Scotland in Pagan Times: Iron Age_, p. 117). Three little bronze figures of boars, from Hounslow, now in the British Museum, are illustrated in the _Proc. Soc. Ant. Lond._ (2nd ser., vol. iii., p. 90); and the splendid bronze shield from the Thames at Battersea, in the same collection, has a boar represented upon it (see Kemble’s _Horæ Ferales_, pl. 14). The boar also occurs on one of the Scotch symbol-bearing slabs at Knock-na-Gael, near Inverness (see Stuart’s _Sculptured Stones of Scotland_, vol. i., pl. 38). For a boar on a helmet, see account of Benty Grange tumulus on p. 67. A portion of the antiquities mentioned are now in York Museum, and the Rev. W. Stillingfleet’s manuscript notes on his diggings in 1815-17 are preserved in the Library of the York Philosophical Institute. The barrow at Arras, opened by the Rev. Canon W. Greenwell, covered a circular grave, 12 feet in diameter, sunk in the chalk to a depth of 3 feet, on the floor of which was laid the skeleton of a woman, resting on the left side, with her left hand up to the face, and the head to the west. Two tame pigs were buried with the deceased, and the grave-goods comprised an iron mirror, a bronze harness-ring, a pair of iron chariot-wheels, two snaffle-bits, and what may have been a whip-shank. In 1875 Canon Greenwell explored a tumulus near Beverley, in Yorkshire, which yielded two chariot-wheels and a bridle-bit, but no human or other bones.
