It is only a side panel from what was once a full altar tomb, a chest-shaped funerary monument raised above floor level, yet even in this partial state it carries an extraordinary density of carved imagery. Across its surface, arranged with evident care, are the instruments of the Passion: a crown of thorns enclosing a heart, hands and feet pierced with nail wounds, a spear, a sponge on a pole, a hammer, pincers, and a ladder. The composition is divided by fluted, tapering columns, and above a projecting horizontal moulding, a frieze of double scrolls paired to form heart shapes runs along the upper section. The whole thing speaks of considerable craft compressed into a single stone face.

The panel dates to the late sixteenth or early seventeenth century and is closely associated in style with the O'Kerin school of monumental sculpture, a workshop tradition active between 1577 and 1637 and probably based in Callan, County Kilkenny. The O'Kerin school produced altar tombs that circulated across the region during a period when such commissions were both an act of piety and a statement of social standing, even as the Reformation was reshaping the religious landscape around the workshops' patrons. That this fragment survived at all, reused and embedded in a wall rather than remaining freestanding, is itself a small piece of history; it suggests the original tomb was dismantled at some point, and the panel preserved by incorporation into the fabric of the building rather than discarded.
