The script itself, a system of early medieval Irish writing that uses notches and strokes cut along the edge of a standing stone, follows a fairly consistent convention: the inscription runs upward from the base along one edge. This stone from Rooves More in County Cork, however, does not follow the rules. The scholar R.A.S. Macalister, who catalogued it in 1945, noted that the inscription begins in the middle of the left-hand angle, runs down to the bottom, then crosses to the base of the right-hand angle and continues upward to the top. It is an unusual path for a text to travel, and it is the kind of quirk that suggests the carver was working around something, or perhaps working from an unfamiliar model.

The stone was found in 1865, along with two others, inside a souterrain beneath the ground at Rooves More. A souterrain is an underground stone-built passage or chamber, typically associated with early medieval settlements and used variously for storage or refuge. Their discovery together suggests the three stones may have been reused as structural material long after their original purpose had ended, a common fate for ogham stones throughout Ireland. All three were removed by A. Lane-Fox and taken to the British Museum, where this stone, measuring 2.1 metres in length and 0.6 metres across, remains today. Macalister read its inscription as VEDACUNA [MAQI] TOBIRA MUCOI SOGINI, a formula typical of ogham commemorations, recording a personal name, a patronymic through the word MAQI meaning "son of", and a tribal or kin group identifier through MUCOI. The inscription is a window into the social structures of early medieval Ireland, naming a person and their belonging within a wider kindred, the SOGINI.

For anyone hoping to see the stone, the journey leads not to County Cork but to the British Museum in London, where it has been held since the nineteenth century. The site in Rooves More where it was uncovered retains its archaeological identity, but the stone itself has been absent from Irish soil for well over a century.
