At Rathmooley in County Tipperary, a carved stone slab was uncovered at a hilltop enclosure set on high ground with wide views in every direction, only to be subsequently destroyed, leaving behind nothing but a brief written description and a set of unanswered questions about what it once meant.

The slab came to light during drainage works in a section of the inner fosse, the defensive ditch running inside an enclosure boundary, at the site recorded as a hilltop enclosure in the uplands of Tipperary. According to the account published by Scott-O'Connell in 1938, it was a roughly rectangular slab of unknown stone type, divided into four sections by crossed lines, with each section engraved with figures and lines. That crossed-line division, creating four quadrants each bearing some form of carved imagery, suggests a deliberate compositional scheme, though without the stone itself, and without any surviving illustration or rubbing, the exact nature of those figures remains unclear. Whether the carving was early medieval, prehistoric, or something else entirely cannot now be determined. The stone has since been destroyed, and the description in the 1938 publication is all that remains.

The enclosure itself still survives on the hilltop, and the site sits within an upland landscape that would have commanded attention in any period. The inscribed slab, however, exists now only as a footnote, a few lines of description for something that passed through human hands and did not survive them.
