Recorded and drawn, it has since been lost to view among the graves, the grass, or the general quiet accumulation of centuries. A graveslab is typically a flat, carved stone laid over a burial, often bearing a cross or inscription, and the Lackan example was documented carefully enough for a draughtsman to render it on paper. Yet when searchers returned to look for it in the graveyard itself, it could not be found.

The site it belongs to has a considerably longer memory than the slab itself. The ruined nave-and-chancel church at Lackan stands on rising ground with wide views to the west, north, and east, and its northern wall now serves as the boundary of a rectangular graveyard. That church was itself built on the site of an Early Christian monastery, Lecan-Midhe, which appears in the Annals of Ulster as early as 750, when the death of Fursu, abbot of Lecan-Midhe, was recorded. The monastery persisted long enough to be absorbed into later medieval arrangements: during the reign of Edward I, between 1272 and 1307, a local landholder named Adam de Ledwyche, also recorded as Ledwith, granted the church of Lackan to the Abbey of Tristernagh, an Augustinian house in the same county. The transfer tied a site with roots in the early Irish church into the more bureaucratic world of Anglo-Norman ecclesiastical landholding.

What remains today is the ruin of that medieval church, a graveyard still in use or at least long used, and the unresolved question of where the slab has gone. It may be face-down, overgrown, or simply overlooked. Visitors to the graveyard who take the time to look carefully along the ground, particularly near the old north wall, may yet find it.
