Whatever person it once marked has been quietly erased by time, leaving behind only a carefully worked piece of stone that records a burial without identifying the buried.

Athassel was an Augustinian priory, a house of canons following the Rule of St Augustine, founded in County Tipperary in the late twelfth century and eventually one of the largest monastic enclosures in medieval Ireland. The slab itself was described by Maher in 1997 as a tapering limestone piece, placed 10.15 metres from the east gable of the chancel. It is modest in scale, roughly 42 centimetres in total length and 48 centimetres wide, with a chamfer, a bevelled or angled edge, cut along both the dexter and sinister sides and across the base. The chamfering is asymmetrical: wider on the right side than the left. No trace of an inscription or decorative motif was identified on the upper surface. The absence of any such marking is itself notable; medieval graveslabs in Irish ecclesiastical settings frequently bore crosses, effigies, or at minimum a name, and a plain chamfered slab of this kind raises quiet questions about whether it was ever finished, whether its markings have simply worn away, or whether the person commemorated was someone for whom a plain stone was considered sufficient.
