Carved into its surface is the incised figure of a prior, one of those medieval effigial slabs where a man is remembered not by a sculpted tomb chest but by a flat, linear likeness pressed into the stone underfoot. Above or around the figure, a Latin inscription runs in Lombardic script, the rounded, decorative letterforms commonly used on medieval ecclesiastical stonework across Europe.

The inscription reads 'HIC IACET BONE MEMORIE QVONDAM PRIOR ISTIUS LOCI', which translates roughly as 'Here lies, of blessed memory, a former prior of this place.' It is a formula of deliberate modesty, or perhaps of genuine anonymity. The man is not named. He is identified only by his office and his house, the Augustinian priory founded at Inistioge on the River Nore in County Kilkenny. The historian William Carrigan recorded the slab in 1905, at which point the inscription was already legible, suggesting the stone had survived the dissolution of the monasteries and several subsequent centuries in reasonable condition. Whether the prior it commemorates was a figure of local consequence or simply a man whose community wished to mark his passing without elaborating further, the record does not say.
