The stone records the deaths of Patrick Flood and his wife Margaret Kowragh, with a year, 1615, but the actual days of their deaths were never filled in, leaving two deliberate gaps in the text that have remained empty for over four centuries. Whether this was an oversight by the mason, a commission abandoned mid-process, or simply the way such work was sometimes left, the stone now reads as a monument with missing information carved permanently into its surface.

The slab itself is a mensa, the flat upper surface of a chest tomb or ledger, cut from fossiliferous limestone, a stone in which the outlines of ancient marine creatures are visible to a careful eye. It measures 1.86 metres long and 0.66 metres wide, and its carved decoration is detailed and deliberate. An eight-armed interlaced cross rises from a stepped base on a knobbed shaft, with fleur-de-lis terminals at each arm and a Maltese cross at the centre of the cross-head; streamers flank the shaft on either side. The marginal inscription, rendered in false relief Latin black lettering, identifies Patrick Flood as a burgess of the city of Kilkenny, a formal civic rank denoting a man of standing within the town's commercial and administrative life. Margaret Kowragh is named as his wife. The stone's history since 1615 includes a move into the floor of a room in the north transept known as the Monuments Room during the 1960s, and a further relocation to the south transept in 2015.
