Cut into its surface is a cross, and roughly a foot below the cross-bar, a pair of grooves runs across the shaft. Those grooves were made to hold something, specifically a small brass tablet, now long gone. Whatever name, date, or inscription that tablet once carried has vanished with it, leaving only the fittings behind.

The fragment was recorded by the historian William Carrigan in 1905, in his multi-volume history of the Catholic diocese of Ossory. Carrigan noted it as part of a tomb, though neither its original form nor its date could be determined even then. The practice of affixing brass tablets or plaques to stone grave slabs was not unusual in medieval and early modern funerary monuments; the brass provided a surface for engraved text or heraldic imagery that the stone itself might not easily accommodate. What makes this fragment quietly interesting is precisely its incompleteness. The stone survives, the grooves survive, and the absence where the brass once sat is itself a kind of record of how the memorial was designed to function.
