Somewhere in the townland of Ballykean in County Wicklow, there is, or was, a small peaked stone bearing cup marks and carved gashes, the kind of abstract incised decoration that appears across Atlantic Europe during the Neolithic and Bronze Age periods. Nobody has seen it in decades, and the last person to leave a useful description of it did so in 1884.

That description came from Kinahan, writing in that year, who catalogued the stone as specimen D in a local survey. His account is brief but quietly interesting: two cup marks, which are small, deliberately ground depressions in the rock surface, and two gashes, one of which he judged to be considerably more recent than the other markings. The older cuts he considered genuinely ancient. That layering matters, because it suggests the stone attracted attention across multiple periods, later hands adding to, or perhaps responding to, what earlier people had made. When the location Kinahan identified was examined again in 1990, the stone could not be found.
