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.
The whole has the appearance of being considerably more modern than Gavr Innis.
Besides these, in the neighbourhood of Carnac and Locmariaker, there are at least three other groups of stones in France which deserve much more attention than has hitherto been bestowed upon them. The first is in the peninsula of Crozon, forming the southern side of the roadstead of Brest. It consists, among others, of three alignments of stones. The principal one is at a place called Kerdouadec, and consists of a single line of stones 1600 feet in length, arranged on a slightly curved plan, and terminating in a curious "Swastica"-like cross. The second, at Carmaret, is a single line, 900 feet long, and with two branches at right angles to it, near its centre. The third, at Leuré, is likewise a single line with a slight elbow in the centre, from which starts a short branch at right angles.[430]
154. Alignments at Crozon.
I am not able to offer a conjecture what these alignments represent, nor why or when they were placed here. Whether an inspection on the spot might suggest some clue is not clear, but they are so unlike anything found anywhere else, either in France or any other country, that they must for the present, I fear, remain a mystery.
The second group, known as the Gré de Cojou, is situated about halfway between Rennes and Redon. The remains here consist of a short double alignment some 500 feet long, several tumuli—one at least surmounted by a circle of stones—several stone enclosures, and frequent dolmens. They have been imperfectly described by M. Ramé,[431] and planned, but not published, by Sir Henry Dryden. Until these are given to the world more in detail than has hitherto been done, it is impossible to say whether they represent a battle-field or a cemetery. From their position—a bleak, barren heath, far from any centre of population—I would guess the former; but I have not visited the place myself, and the information at my command is too meagre to enable me to speak with any confidence regarding them.
