The stones were not placed there as a monument in the conventional sense; they had been repurposed as structural lids over a souterrain, the kind of dry-stone underground chamber that early medieval Irish communities built for storage or refuge. That fourteen of those stones carried ogham inscriptions, the early Irish script that runs sequences of notches and scores along the edge of a stone to record names and lineages, tells us something quietly remarkable about how the past was being dismantled and reused even in antiquity.

This particular stone, a sandstone slab measuring just under five feet tall and roughly twenty-two inches wide, carries its inscription along the dexter angle and across the top, cut in what scholars describe as "knife-cut" scores rather than the more deeply incised strokes found on grander examples. The condition is poor, which has led to some variation in how the text has been read. Robert Macalister, writing in 1945, rendered the inscription as GRILAGNI MAQI SCILAGNI, a formula typical of ogham stones, where MAQI means "son of" in Old Irish, giving a reading of something like "Grilagni, son of Scilagni". Damian McManus, working from a fresh examination published in 2004, produced a closely related but slightly differing transcription, grILAGNI MAQi SCILAGNi, with the lower-case letters indicating characters he considered less certain. The personal names themselves are otherwise obscure, not easily paralleled elsewhere, which adds a layer of linguistic interest for those working on early Irish onomastics.

The stone is no longer in Cork countryside but on permanent display in the Stone Corridor at University College Cork, where it sits among a collection of ogham stones that makes the corridor one of the more concentrated repositories of early medieval epigraphy in Ireland. It is accessible to visitors during normal university opening hours, and seeing the inscription in person gives a sense of just how slight and worn those knife-cut scores are, the kind of detail that photographs rarely convey.
