The piece, catalogued from Leggetsrath in County Kilkenny, is wedge-shaped, roughly the size of a large hardback book, and bears the quiet marks of a long and complicated life.

The block is described as possibly having been reused as a voussoir, one of the wedge-shaped stones that lock together to form an arch, which would explain its tapered profile, wider at the top than at the base. What makes it genuinely puzzling is what remains of its surface. Most faces appear to have been crudely chiselled, or else carry the ghost of a decorative pattern so worn and eroded that it now reads only as a pitted, pocked texture. Whether the carving was deliberately obscured when the stone was repurposed, or whether centuries of exposure simply reduced it to this ambiguous state, is not clear. The dimensions are modest: 0.27 metres across at the widest point, 0.32 metres tall, and 0.175 metres thick. It is the kind of object that archaeologists sometimes call a spolia, a piece stripped from one structure and pressed into service in another, carrying traces of an original context that can no longer be fully read. The stone is held in the Office of Public Works store in Kilkenny, assigned depot reference KD036.
