Carved into the stone is a floriated raised cross, the Christogram "IHS", and, perhaps most intriguingly, a salmon in relief. The presence of the fish is the kind of detail that makes you pause; it sits alongside devotional imagery with an easy familiarity, suggesting a personal or family connection rather than purely liturgical convention.

The slab dates to around 1580 and commemorates a man named Peter Joyce. A Latin inscription in Black Letter, the angular script associated with medieval and early modern stonework, runs around the edge of the upper section of what was originally a chest tomb, a free-standing box-shaped monument raised above the floor of the chapel. Chest tombs were a mark of some social standing, and the quality of the carving here, the intertwined crosses and the careful lettering, points to a family with the means to commission skilled work. The Augustinian Priory itself, founded in the thirteenth century, was already a venerable institution by the time the Joyce slab was laid, and the Lady Chapel would have been a prestigious location within it.

The priory ruins are accessible in the village of Inistioge, and the Lady Chapel section where the slab survives is visible within the remains of the complex. The upper portion of the tomb is what endures; the base has not survived, which is common for chest tombs of this period, where later disturbance or reuse of stone often accounts for losses.
