Measuring just 0.84 metres long and 0.44 metres wide, it is a modest piece of fossiliferous limestone, the kind in which the compressed remains of ancient sea creatures are visible in the stone itself. Rough Roman capitals cut into its surface read, in the spelling of its age, "This is the intrance of Mr. Jasper Roothe Monument." It is not a memorial in the conventional sense, but a marker for the entrance to a vault beneath, directing the eye and the foot downward rather than offering an epitaph or a carved portrait.

The slab almost certainly marks access to the vault below the tomb of Richard Rothe Fitz Edward, connecting it to one of the prominent Rothe family of Kilkenny. A Jasper Rothe is recorded in genealogical research by Burtchaell, published in 1886, as having died in 1623. The phrasing on the stone, with its directional plainness, belongs to an era when vault markers served a practical purpose as much as a commemorative one, identifying whose underground burial space lay below so that rights to it were clearly established. The fossiliferous limestone used here was a common choice in the region, worked with modest rather than elaborate tooling, which gives the inscription its slightly rough, unpolished character.
