At about the same distance west from Belfast is another dolmen, which, in itself, is a much finer example than this Grave of the Giant. Its cap-stone is said to weigh 40 tons, and is supported by five upright stones of considerable dimensions. It has, however, no circle or accompaniments. The Celtic name of the district in which it stands was 'Baille clough togal,' _i.e._ the Town of the Stone of the Strangers, which would seem to indicate that it was not very old, nor its origin quite forgotten. [Illustration: 78. Dolmen at Knockeen.] At Knockeen, county Waterford, there is a remarkable dolmen (woodcut No. 78), though it neither has any surroundings nor any tradition attached to it.[260] It is interesting, however, as it looks as if we were approaching the form out of which Stonehenge grew, which, I have not a doubt, could be found in Ireland if looked for. It is also interesting as showing in plan (woodcut No. 79), an arrangement which is peculiar, I believe, to Irish dolmens. The cell is well formed, but in front of it is a demicell, or ante-chamber, which looks as if it might have been used for making offerings to the dead after the cell was closed. [Illustration: 79. Plan of Dolmen at Knockeen.] [Illustration: 80. Calliagh Birra's House, north end of Parish of Monasterboice.] One other dolmen deserves being illustrated before going further, as it belongs to a class of monuments common in Brittany, hitherto unknown in Great Britain. It consists of a cell 12 feet 8 inches long internally, with a width of 4 feet at the entrance, but diminishing to 3 feet at its inner end. It is situated near Monasterboice, at the northern limit of the parish, and not far, consequently, from New Grange, and close to Greenmount. Locally it is known as the house or tomb of Calliagh Vera, or Birra,[261] the hag whose chair is illustrated in woodcut No. 73, and whose name is indissolubly connected with the Lough Crew tombs. According to the traditions collected by Dr. O'Donovan and Mr. Conwell, she broke her neck before completing the last tumulus, and was buried, close to where she died,[262] in the parish of Diarmor, where, however, nothing remains to mark the spot. From the mode in which it is constructed, it seems hardly doubtful that the original intention was to cover it with a tumulus; but probably it never was occupied. If I am correct in my surmise as to its age, its builder may have been converted to Christianity before he had occasion for it. But, be that as it may, its exposed position may serve to explain how a king or chief who had erected such a structure for his burying-place might very well have amused himself, if his life were prolonged, in adorning both the interior and exterior with carvings. I cannot believe that the internal ornaments were ever executed by artificial light, and both, therefore, must have been completed before the chamber was buried.
