It carries no inscription, no knotwork, no cross; just a smooth, undecorated face pointing upward at the sky. What makes it quietly curious is not what it says but what it omits, and the manner in which it nearly slipped out of the record entirely.

The scholar R. A. S. Macalister surveyed the graveyard between 1916 and 1917, producing a detailed plan of the site. He drew this slab, placing it carefully on his diagram, but assigned it no number, as though it belonged to a category too plain to warrant one. Its position is known precisely: 18.9 metres from the southern wall of the Saints' graveyard and 7.6 metres from the western wall. That level of measurement implies it was considered worth locating, even if not worth classifying. A recumbent graveslab, as the term suggests, lies horizontal rather than standing upright, typically placed directly over or near a burial. The absence of decoration here is not necessarily a sign of poverty or low status; early medieval Irish grave markers were often left bare, their significance residing in placement rather than ornament.
