These cupmarks, as they are known, are among the most enigmatic carvings in the Irish archaeological record. They appear on rocks and boulders across Ireland and Britain, almost always without any accompanying inscription or context that might explain their purpose. Ritual, territorial, astronomical, and purely decorative functions have all been proposed, and none has been convincingly settled.

The boulder sits in pasture on a south-facing slope near Drinagh, with Curraghalicky Lake visible to the south-east below. What makes its situation particularly interesting is that it was not placed here as a monument in its own right. Rather, it was dumped, at some unknown date, on the south-eastern bank of a ringfort. A ringfort is a roughly circular enclosure, typically defined by an earthen bank and ditch, used as a farmstead during the early medieval period, broadly from around the fifth to the twelfth century. Whether the boulder was moved from elsewhere on the landscape, whether it was always in the vicinity of the ringfort, or whether its cupmarks had any meaning to the people who later built that enclosure, is simply not known. The two features belong to different periods, and their proximity may be coincidental, the boulder perhaps shifted to clear a field or define a boundary long after the ringfort itself had fallen out of use.

The four cupmarks are described as shallow, which is not unusual for this type of carving. They can be easy to miss in flat light but become more legible when the sun is low and raking across the surface of the stone, throwing the small depressions into relief.
