"Here do you who pass by," its Latin inscription demands, "whether you are a great fellow, an ordinary person, or a mere lad, pour forth prayers for me." The directness is arresting, and all the more so because the stone was carved not after a death but, apparently, during one. Edmund Hacket and Anna Rokel commissioned or at least presided over this slab while engaged in the restoration of the medieval parish church of St John the Baptist, the building that would eventually become Holy Trinity. Hacket died on the 27th of July 1508, the inscription records, in the very act of that pious work.

The slab itself is a substantial piece of craft: 2.18 metres long and just over a metre wide, decorated in relief with a seven-armed segmental-headed cross whose terminals end in fleur-de-lis, and whose shaft rests on a pillar-base form with a three-barred knop marking the junction of shaft and head. On either side of the shaft sit two heraldic shields, each identifying one of the commemorated parties. The dexter shield, on the viewer's left when facing it, carries three hakes shown upright in the manner known in heraldry as hauriant, above the name "Hacket"; the sinister shield opposite bears a lozengy pattern, rows of alternating diamond shapes, above the name "Rokel". The inscription itself is cut in Black Letter script and runs around the border before continuing along the shaft, base, and head of the cross. Its tone shifts as it goes. One section, translated and published by FitzGerald in 1903, records the straightforward memorial formula; another, noted by Garstin in 1892, is something more unusual: an address to Christ insisting the stone was placed not to ornament the body but to keep the soul in memory. It is a medieval commonplace, perhaps, but one rarely so plainly stated on a surviving Irish slab.
