Held in the Stone Store at the site's visitor centre, this cross-slab from Sevenchurches is a relatively modest object, an erect slab with a rounded top, around half a metre thick, but its incised decoration belongs to a precise and ancient tradition. Carved into its face is a Greek cross, the kind with four equal arms rather than the elongated Latin cross of later Christian iconography, its ends splayed outward and the whole design enclosed within a circle and set upon a long stem. That combination, cross, circle, and stem, is a form that appears repeatedly in early Irish ecclesiastical carving, and seeing it rendered here in simple incision rather than high relief gives a sense of how this visual language worked before the great high crosses made it monumental.

The slab was documented in detail by Harold Leask in his 1950 study of Glendalough, a careful survey of the national monuments then vested in the Commissioners of Public Works. Leask recorded the dimensions and described the design with the measured precision typical of mid-twentieth-century antiquarian scholarship. Sevenchurches is the older name for the valley and monastic complex now more widely known as Glendalough, a site of early Christian settlement associated with St Kevin and continuously occupied from around the sixth century. The name reflects the number of ecclesiastical buildings once scattered across the valley, several of which survive in some form today. That this particular slab ended up in storage rather than in situ is not unusual; smaller carved stones at such sites were often moved indoors to protect them from weathering and handling.
