If any history were attached to these Western dolmens, or any remains had been found under them which would enable us to fix their dates, even approximately, or to arrange them in any intelligible sequence, it might be worth while recapitulating their names or illustrating their forms. Nothing of the sort, however, has yet been attempted; and apparently no materials exist from which any such series could be elaborated. [Illustration: 51. Arthur's Quoit, Gower. From a drawing by Sir Gardner Wilkinson.] [Illustration: 52. Plan of Arthur's Quoit.] Only one dolmen in Wales, so far as I know, bears a name; but it is the illustrious one of King Arthur. The dolmen bearing his name is situated in the peninsula of Gower, on the northern slopes of the bleak Bryn Cefn, about ten miles west from Swansea.[196] It forms the centre of a very extensive group of monuments--eighty cairns, at least, are still to be counted in an area less than half a mile in length, by a quarter of a mile in width. These are mostly small, 12 to 15 feet in diameter; one, 20 feet across, was opened by Sir Gardner Wilkinson, but proved to contain no interment. The largest is 68 feet in diameter, but has not been opened. About 350 feet from this is the dolmen. The cap stone is 14 feet 6 inches in length, 7 feet 5 inches in height, and 6 feet 8 inches in breadth even now, but a very large piece has been broken off, and now lies beside it, measuring upwards of 3 feet in thickness; and another piece seems to have been broken off on the other end, so that when complete it must have weighed between 35 and 40 tons. It rested originally on ten or eleven upright stones, two of which, however, have fallen, and only four now touch the cap stone. Sir Gardner is of opinion that it once was covered with a tumulus; but this appears very doubtful. The slight mound, backed up with large stones, that now surrounds it, with a diameter of 73 to 74 feet, seems an enclosure more like that of Hob Hurst's House (woodcut No. 53) than the remains of a tumulus, and till some further evidence is adduced, we must be allowed to doubt whether any cap stone on legs was ever so treated. Sir Gardner traced, doubtfully, an avenue, of which, however, only five stones now remain, extending to about 500 feet in a direction that would have passed the dolmen on the north, as that at Shap did the circle at its front, or the lines at Merivale Bridge, the circle still found there; Sir Gardner also points out some small circular enclosures, which, from the analogy of those found on Dartmoor, he assumes to be hut-circles.
