At Eoghanacht on Inis Mór, a small subrectangular slab lies just a couple of metres from a site known as Leaba an Spioraid Naoimh, meaning the Bed of the Holy Spirit, and its simplicity is precisely what makes it worth pausing over. The stone measures 0.78 metres high, 0.48 metres wide, and 0.14 metres thick; modest dimensions for something that has survived long enough to be catalogued by scholars across two generations.

The slab carries a Latin cross, the most elementary form in early Christian carving, where the upright shaft and two horizontal arms meet at right angles without any elaboration of the terminals. What is notable here is the technique: the shaft is formed from two incised lines running parallel, while each arm is cut with a single line. It is a minimal grammar, the kind of mark-making that suggests a carver working carefully but without pretension, defining a sacred symbol through restraint rather than ornament. Cross-slabs of this type, flat stones incised or relief-carved with a cross, were used across early medieval Ireland as grave markers or devotional objects, and they cluster particularly around monastic and ecclesiastical sites. The proximity of this example to Leaba an Spioraid Naoimh places it within what was evidently a locally significant sacred landscape. The site appears in the scholarly record in John Waddell's 1973 survey and again in James Higgins's 1987 study of Aran monuments, suggesting it has been recognised as genuinely early rather than a later imitation.
