The Picts, or whoever they were, might assuredly use charm stones, and the only objection to the idea that they might engrave archaic patterns on them is the absence of record of similarly inscribed small stones in Britain. The custom of using magic stones was not at all incongruous with the early Pictish civilisation, which retained a form of the Family now long outworn by the civilisation of the Arunta. The sole objection is that a silentio, silence of archaeological records as to inscribed small stones. That is not a closer of discussion, nor is the silence absolute, as I shall show.
Moreover, the appearance of an unique and previously unheard-of set of inscribed stones, in a site of the usual broch and crannog period, is not invariably ascribed to forgery, even by the most orthodox archaeologists. Thus Sir Francis Terry found unheard-of things, not to mention “a number of thin flat circular discs of various
sizes” in his Caithness brochs. In Wester broch “the most remarkable things found” were three egg-shaped quartzite pearls “having their surface painted with spots in a blackish or blackish-brown pigment.” He also found a flattish circular disc of sandstone, inscribed with a duck or other water-fowl, while on one side was an attempt, apparently, to write runes, on the other an inscription in unknown cursive characters. There was a boulder of sandstone with nine cup marks, and there were more painted pebbles, the ornaments now resembling ordinary cup marks, now taking the shape of a cross, and now of lines and other patterns, one of which, on an Arunta rock, is of unknown meaning, among many of known totemic significance.
Dr. Joseph Anderson compares these to “similar pebbles painted with a red pigment” which M. Piette found in the cavern of Mas d’Azil, of which the relics are, in part at least, palaeolithic, or “mesolithic,” and of dateless antiquity. In L’Anthropologie (Nov. 1894), Mr. Arthur Bernard Cook suggests that the pebbles of Mas d’Azil may correspond to the stone churinga nanja of the Arunta; a few of which appear to be painted, not incised. I argued, on the contrary, that things of similar appearance, at Mas d’Azil: in Central Australia: and in
Caithness, need not have had the same meaning and purpose. [95a]
It is only certain that the pebbles of the Caithness brochs are as absolutely unfamiliar as the inscribed stones of Dumbuck. But nobody says that the Caithness painted pebbles are forgeries or modern fabrications. Sauce for the Clyde goose is not sauce for the Caithness gander. [95b]
The use of painted pebbles and of inscribed stones, may have been merely local.
In Australia the stone churinga are now, since 1904, known to be local, confined to the Arunta “nation,” and the Kaitish, with very few sporadic exceptions in adjacent tribes. [95c]
The purely local range of the inscribed stones in Central Australia, makes one more anxious for further local research in the Clyde district and south-west coast.
