That last detail is the unusual one. Medieval stonework in Ireland rarely preserves the name of its maker, yet this slab, cut in 1587, closes with a line of black-letter Latin that reads: "Patrick O'Tunny inscribed this tomb." The slab itself is a tapering piece of limestone just under two metres long, decorated with a seven-armed floriated cross, a three-bar knop beneath the cross head, and a shaft resting on a curving Calvary mount, the raised mound associated in Christian iconography with the site of the Crucifixion. A shallow chamfer runs around the edge, and the Latin inscription occupies a margin on three sides, stopping short of the base.

The slab commemorates James Stokes and Margaret Butler, his wife, who are recorded in the inscription as the patrons who commissioned it: "who got me made," in the translated phrasing, a small but pointed reminder that the object itself is speaking. The Butler family, one of the most powerful dynasties in late medieval Munster and Leinster, appear frequently in the fabric of Kilcooly Abbey, a Cistercian house in County Tipperary with deep ties to Butler patronage. The date of 1587 places the commission well into the post-Reformation period, though the Latin formula and the invocations of the Our Father and Hail Mary are thoroughly Catholic in character. The inscription was transcribed and translated by Carrigan in 1903, and the slab is likely the same "floor slab, much worn" noted by Hunt in 1950, suggesting it was at some point moved from the floor to its current position on the wall, where it has been better preserved.
