What survives is the broken upper portion of what was once the lid of a chest tomb, a box-like raised monument in which the coffin or remains were enclosed within a rectangular stone surround topped by a carved slab. This piece measures less than a metre across and barely a centimetre thick at some edges, yet despite heavy spalling and a clean break across its lower section, it retains a remarkable concentration of imagery and text.

The slab commemorates Thomas Comerford, and was carved around 1610, placing it in the generation after the Elizabethan conquest reshaped so much of Kilkenny's landowning class. A partial Latin inscription runs along the top and left-hand border in Roman capitals, reading HIC JACET THOMAS COMOFORT DE, the family name rendered in an older anglicised spelling before the text breaks off with the stone itself. The central carved motif is a raised cross with trefoil terminals, each arm connected to the next by a curving line, giving the whole design a fluid, almost organic quality. Where the arms of the cross meet at the centre, the Christogram IHS is carved, a widely used devotional abbreviation of the name of Jesus. What makes the composition genuinely unusual is the figurative detail in its two upper corners: a sun with a face occupies the upper right, and a moon with a face the upper left. These personified celestial bodies appear in late medieval and early modern religious iconography, often flanking crucifixion scenes as symbols of cosmic witness to Christ's death, and their presence here on a provincial Kilkenny graveslab of around 1610 quietly places this broken fragment within a much wider European visual tradition. The historian Carrigan, writing in 1905, noted the stone as a sculptured fragment dating to about 1600, which at least confirms it was already recognised as significant more than a century ago. The slab sits 1.8 metres northwest of Killamery's well-known high cross, itself a medieval monument of considerable age, making this corner of the graveyard an unusually dense pocket of carved stonework.
