That particular kind of absence, a recorded thing that has quietly slipped from the record of the physical world, gives the site an unusually melancholy quality.

The stone in question was documented in 1884 by G.H. Kinahan, who described it as a thick granite flag that appeared to have been deliberately laid flat by human hands. Its surface carried cup marks, a form of prehistoric rock art consisting of shallow, roughly circular depressions carved or pecked into stone, whose purpose remains a matter of debate among archaeologists. Kinahan noted that the surface was heavily weathered, to the point where some of the cups had eroded into one another, blurring the boundaries between individual marks. The field in which it sat was known locally as "fort field", a name that suggests some memory, however vague, of earlier significance attached to the ground. When the site was revisited in 1990, the field had been cleared of stone, and Kinahan's "Stone B" was nowhere to be found. Whether it was broken up, buried, moved, or simply overlooked is not recorded.
