Casgliadau Arlein

A piece of greenish, micaceous sandstone, such as was used in the phase IV and V paving of the baths, and evidently broken from the wall-cladding, for the stub of an iron cramp remains on one side. The stone has been ground flat on all four of its long sides to give a square section. Both ends have also been ground flat, and the edges bevelled with ground facets. Possibly a whetstone.
