Somewhere in the small graveyard at Coolfinn, a stone effigy of a bishop once lay in a Romanesque parish church, inscribed with a name that raises more questions than it answers. The carving bore the legend S. MONNIA EPISCOPS, a puzzling designation given that Monnia, also known as Darerca or Moninne, is traditionally recorded as a female saint and abbess, not a bishop. Whether the inscription reflects a local tradition, a scribal confusion, or something else entirely, the effigy is no longer there to examine. It has gone missing, and its whereabouts remain unknown.

The church in question is the medieval Romanesque parish church of Guilcagh, a building that already occupies an atmospheric position on the edge of the River Suir floodplain in County Waterford, with the Kilbunny Stream running some thirty to forty metres to the south-east. Romanesque architecture in Ireland, which flourished roughly in the twelfth century, is characterised by its rounded arches and often intricate stone carving, and Guilcagh sits within a small rectangular graveyard that still survives. The effigy itself was dated to the sixteenth or seventeenth century, measuring approximately 0.75 metres by 0.4 metres, and was documented by scholars including Power in publications from the late nineteenth and early twentieth centuries. By the time its absence was confirmed through communication with the National Museum of Ireland, it had already slipped out of the record entirely.
