Chest tombs of this period typically consist of a box-like structure with a flat covering slab, and this one measures just over two metres in length. What sets it apart is the sheer density of imagery carved across its front face: a catalogue of the Arma Christi, the instruments or symbols of the Passion of Christ, rendered in careful sequence across a surface not much taller than two feet.

The symbols run from one side to the other in a deliberate order: a ladder, entwined ropes, a spear, dice alongside a seamless garment, thirty pieces of silver with a bag bearing two straps, a cross ringed with a crown of thorns, a heart pierced with nails, pierced hands and feet, a scourge flanking a plant, a cock perched on a three-legged pot, a sword, a chalice, a hammer, and pincers gripping three nails, with two sheaves of wheat completing the sequence. Each of these objects corresponds to an episode in the Passion narrative, and their arrangement here would have been immediately legible to a seventeenth-century Catholic viewer. The whole composition is framed by stylised fluted pillars that taper toward the base. The Latin inscription running around the edge of the upper slab commemorates two people: Richard Comerford, formerly of Danganmore, whose date of death was never cut into the stone and remains blank, and his wife Johanna St. Leger, described as a matron pious, hospitable, and charitable to all, who died on the fourth of October 1622. The inscription was transcribed by Carrigan in 1905 and the tomb's decoration was later illustrated by Phelan in 1973.
