Floor slabs of this kind were a common enough practice in medieval and early modern churches, where families of means could secure burial within sacred walls and mark the spot with an inscribed stone, effectively embedding memory into the architecture itself. What makes this one linger is the partial survival of its Latin text, carved in high relief with Gothic lettering, reaching out across four centuries in fragments.

The slab commemorates Dominic Creagh and his wife Genete Creagh, and according to the inscription records a date of 28 November 1632. The text follows a familiar intercessory formula beginning with the words "Orate pro animabus," meaning "pray for the souls of," which was standard in Catholic memorial practice of the period. The Urban Survey of Limerick, compiled by Bradley and others in 1989 and drawing on an earlier transcription by FitzGerald from 1910, records the inscription with its gaps and one noted repetition marked "sic," indicating the original carver's error was faithfully copied rather than corrected. The Creagh family were a prominent merchant dynasty in Limerick, and their association with the Arthur chapel within the cathedral points to the layered civic and religious lives of the city's Catholic merchant class in the early decades of the seventeenth century.

St. Mary's Cathedral is an active place of worship as well as a visitor attraction, and access is generally available during daylight hours. The Arthur chapel is within the cathedral interior, so the slab rewards a slow circuit of the building rather than a direct approach. The inscription, being in high relief, is best read in raking light, when the carved lettering casts enough shadow to make the surviving text legible. The gaps and lacunae in the transcription are themselves part of the record, a reminder that stone weathers, and that what survives does so unevenly.
