What makes this fragment particularly striking is a circular hollow worn into the lower portion of the stone, a depression left by the swivel of a door post. At some point after it was laid down, this slab was lifted and repurposed as a threshold, the pivot of a door grinding slowly into its surface over years or decades before it was eventually returned, or simply left, to rest on the church floor.

The slab almost certainly once marked the grave of John Tobyn, rector of this church and founder of a new chantry, a privately endowed chapel where priests were paid to sing masses for the souls of the founder and named others. When the historian William Carrigan described the stone in 1905, the cross was still recognisable as an interlaced design in raised relief, and a lengthy inscription in Black Letter script ran around the edge and continued in four lines alongside the cross-shaft. That inscription, as Carrigan transcribed and translated it, recorded Tobyn's death on 21 March 1541, and closed with the line "Rory O'Tunny made me", naming the craftsman who carved it. In an unpublished revision of his work in 1923, Carrigan amended the date to 30 May, a discrepancy that was later noted by Ó Fearghail in 1996 and has never been fully resolved. Today the inscription has vanished entirely from the stone's surface, worn away or obscured by the same generations of use that snapped the slab into pieces and scooped a hollow in its face, leaving a small biographical puzzle and a carved cross with no head.
