The grooves are cut in multiple lines, giving the design a deliberate, layered quality. It is easy to walk past an object this small, and yet it has travelled a considerable distance, geographically and historically, to reach its current display case.

The slab was originally found within the remains of a church on Illaunmore Island, one of the islands of Lough Derg, the long lake that marks the boundary between Clare, Tipperary, and Galway. Cross-slabs of this kind, flat stones bearing incised crosses, are among the more common survivals of early Irish Christianity, often associated with monastic enclosures or church sites where they may have marked graves or served a devotional function. The Illaunmore church is a ruined structure, and the slab, recorded by the historian Gleeson in 1955, was at some point removed from the island site and brought to the museum. At just 25 centimetres tall and 22 centimetres wide, with a thickness of roughly 6 centimetres, it is a physically modest object, but its origins on a lake island give it a particular resonance. Island churches in Lough Derg were frequently early medieval foundations, places chosen for their seclusion, and the carved stone that once sat inside or nearby that remote building is now preserved in a county town, far from the water.
