Measuring just over six feet in length and roughly three-quarters of a metre wide, the limestone slab lies to the north of the central aisle column within the friary, and its decoration combines that agricultural motif with a small cross. The pairing is quietly arresting. Ploughs appear only rarely on medieval Irish grave monuments, where the usual vocabulary runs to swords, chalices, foliate scrolls, and figures of the deceased. To find one here, in a Franciscan friary in east Galway, suggests that whoever commissioned the stone wanted to signal something specific about how the family understood itself and its place in the world.

The inscription, recorded by Bradley and Dunne in 1992, reads: "Pray for the soule of Hugh McCathe, Ivne Kien his wife, and [a name now lost], their son, and their posterity." The spelling is phonetic and the lettering archaic, with the characteristic early modern substitution of V for U throughout. The family name McCathe is not one that appears prominently in the standard genealogical records of Connacht, which makes the slab something of an orphan document; the plough may be the clearest statement the family left behind about who they were. The damaged portion of the inscription, where a son's name has been lost to wear or breakage, gives the stone a particular quality of incompleteness. A family asked to be remembered in full, and time has ensured they are remembered only in part.
