“In the large and almost complete circle at Cothiemuir, in the parish of Keig, the recumbent stone is of peculiar rounded shape, and has numerous hollows upon its surface, caused by weathering. Two of these on the outside, rather larger than their fellows, are known as the ” Devil’s Hoofmarks,” their shape resembling the mark of a cloven hoof.”
