circles, and flowing lines nearly equidistant, but, except on one stone, never of spirals, and then less graceful than the Irish. The sculpture, however, on some of the stones at Lough Crew, and that in the centre especially of woodcut No. 75, is absolutely identical with the patterns found here; and altogether there is more similarity between these sculptures and those at Lough Crew than between almost any other monuments of the class that I know of.
In the chamber on the left-hand side is a stone (woodcut No. 153), with three holes in it, which have given rise to an unlimited amount of speculation. Generally it is assumed that it was here that the Druids tied up the human victims whom they were about to sacrifice. But, without going back to the question as to whether there ever were any Druids in the Morbihan, would any priest choose a small dungeon 8 feet square and absolutely dark for the performance of one of their greatest and most solemn rites? So far as we know anything of human sacrifices, they were always performed in the open day and in the presence of multitudes. Assuming for the moment, however, that these holes were intended for some such purpose, two would have sufficed, and these of a form much simpler and more easily cut. As will be seen from the woodcut, not only are the three holes joined, but a ledge or trough is sunk below them which might hold oil or holy water, and must, it appears to me, have been intended for some such purpose.
The existence of these holes seems to set at rest another question of some interest. Generally it has been assumed that the tattooing on the stones of the chambers, &c., may have been done with stone implements. This cannot be denied, though it seems improbable; but the undercutting of the passages between these holes and the formation of the trough could only be effected by a tool which would bear a blow on its head, and a heavy one too, or, in other words, by some well-tempered metal tool.
At Tumiac, opposite Gavr Innis, existed a very large tumulus, which was opened in 1853 by Messrs. Fouquet and L. Galles. It was found to contain a small chamber, partly formed of large slabs, partly of small stones. Some of the former had rude carvings upon them, but without any meaning that can now be made out.
