The author writes, "This object bears a remarkable similarity to the decorated stone balls of Scotland, which are commonly ascribed to the earlier prehistoric period. Their specific period of currency remains uncertain, however, as very few examples have been found in secure archaeological contexts, and there are indications that they may have continued in use into the first millennium AD."
Macalister described it thusly: "A spherical ball of sandstone, 2" in diameter. It was found in the North Field, close to the large stone on edge. Grooves were cut upon it, which can best be described by likening them to two circles of longitude intersecting at right angles, and two latitude rings corresponding to the Arctic and Antarctic circles of a terrestrial globe. The object has a close analogy to the remarkable balls which are prominent among the prehistoric remains of Scotland.” (Macalister, R. A. S., and R.
