The fragment, measuring roughly 41 centimetres tall and 35 centimetres wide, is believed to have originated in Owning, County Kilkenny, yet it ended up catalogued under Tipperary. How it made that journey, and when, is not recorded.

The panel is a remnant of a chest tomb, a type of free-standing box-shaped monument common in medieval Irish funerary practice, typically comprising a rectangular stone chest set on a plinth and decorated on its side panels. This particular example is limestone, only five centimetres thick, and has not survived intact. The upper corners on both left and right are missing, and the left side has broken away entirely. Where the stone is whole, a narrow plain margin runs along the upper, lower, and right edges, framing the carved surface in the understated manner typical of late medieval craftsmanship. The surviving decoration consists of the symbols of the Passion, the collection of objects associated with the crucifixion of Christ, including instruments such as the cross, nails, the crown of thorns, and the lance. These Arma Christi, as they are known, were among the most common motifs on Irish tomb sculpture from the fifteenth and sixteenth centuries, serving both as devotional imagery and as a visual statement of piety on behalf of the deceased and their family.

The connection to Owning in Kilkenny links the panel to a broader cluster of medieval remains associated with that area, though the fragment itself now lives at a remove from its probable origin. Small and damaged as it is, it carries enough detail to suggest it was once part of something considerably more elaborate.
