Originally from Bunkilla in County Cork, this ogham stone measures 2.2 metres in length and just 0.3 by 0.15 metres across, making it an imposingly slender slab. Ogham is an early medieval script used primarily in Ireland, in which letters are represented by groups of notches and lines cut along the edge of a stone, most often to record a personal name or lineage. What makes this particular stone quietly complicated is that it carries a message scholars are still not entirely sure how to read.

The stone came to light in 1982 during drainage works at Bunkilla, a discovery of the sort that reminds you how much early medieval material still surfaces through mundane civil engineering. Lankford, writing in 1993, read the inscription as either ANM MAQQI-LASIR K[O]I MA(Q)QI BIR(R)AC(I)AS or ANM MAQQI-LASIRE(O)N MAQQI BIR(R)ACIAS, but noted uncertainty around several of the letters. One further reading, proposed in Power's 1997 catalogue, simplifies things slightly to ANM MAQQI-LASIRE MAQQI BIRRAC, which translates roughly as "name or inscription of Mac-Laisre, son of Berrach." The complication is that some letters Lankford identified may actually belong to an even earlier inscription cut into the same stone, meaning the surface may carry two separate layers of text from different periods. The stone has since been documented as part of the Ogham in 3D project, run by the School of Celtic Studies at the Dublin Institute for Advanced Studies, which uses three-dimensional scanning to record the inscriptions of ogham stones across Ireland and make them accessible for detailed study.

Because this entry records the stone's present location in Dublin South City rather than its original findspot in Cork, visitors wanting to see it should look into its current institutional home before making a trip. The Ogham in 3D project's online database, accessible at ogham.celt.dias.ie, holds scanned records and further epigraphic detail for this stone under its Bunkilla entry. For anyone interested in the palaeography rather than the physical object, the digital record offers a level of resolution that a quick viewing in person rarely can.
