On the cover of Sir James Simpson's book, stamped in gold, is a central set of six concentric circles, surrounding a cup. From the inmost circle a groove goes to the circumference of the outer circle (the circles often occur without this radial groove), and there the line gives a wriggle, suggesting that the circle was evolved out of a spiral. Above and below this figure are a similar one with three and another with four concentric circles; at each side are two-circled and one-circled specimens with the wriggled line, and two cups and circles with no wriggle. Now compare fig. 131, p. 631, of Messrs Spencer and Gillen. Here we have the churinga ilkinia, or sacred rock-drawing, in red and white, of the honey ant totem in the Warramunga tribe. Here are, first, seven concentric circles, through the centre of which goes a straight line of the same breadth (only found among the Warramunga), while to each extremity are added two concentric circles of small dimensions, ending in a cross. Around, as on Sir James's cover, are smaller sets of less numerous concentric circles, exactly like Sir James's, except for the radial groove which ends in a wriggle. Again (fig. 124, p. 615), we have two sets of concentric circles with white dots answering to cups, and, where the third set of circles should be, is a volute, as at New Grange, in Ireland, and in many other examples in our islands.

Now, in Central Australia the decorative motives, or analogous motives, of the permanent rock-paintings are repeated on the small portable churinga, which are deciphered by the blacks in a religious, or rather in a mythical, sense. It is, therefore, arguable that the small portable Scottish cup and circle marked stones, only recently discovered, bore the same relation to the engravings on permanent stones, scalps, and boulders as do the Australian churinga to the Australian sacred rock-paintings. They may have been portable sacred things.

I have been unable to visit Dumbuck, now in course of excavation, and have only seen some casts and pen-and-ink sketches sent to me by Mr. Donnelly. But I have examined the similar objects from Dunbuie, in the museum at Edinburgh. The antiquaries looked dubiously on them, because they had seen no such matters before (they might have done so in Ireland), because a shell, with a very modern scratched face, was among the finds, and because a few of the markings on one or two stones look recent and fresh. But I argue that a Dumbarton humourist wishing to hoax us Monkbarnses would hardly 'salt' an old site with objects unknown to Scottish antiquaries, yet afterwards discovered in Central Australia. How could the idea occur to him? A forger would forge things known, such as flint weapons; he would not forge novelties, which, later, are found to tally with savage sacred things in actual use.

Many of the Dunbuie finds are engraved in Mr. Millar's paper on Dunbuie.[4] But he has not engraved the most unmistakable churinga, a small oval slab of stone, with an ornament of little cups following its outline (much as in an Irish instance), and provided, like stone churinga in Australia, with a hole for suspension.

He does engrave certain hitherto unheard-of articles-spearheads of slate, two supplied with suspension holes. One (p. 294) has a pattern of the simplest, like a child's drawing of a larch, which recurs in Australia.[5] That these slate spear-heads, pierced for suspension, were used in war I doubt, though some Australians do use spear-heads 'of a flinty slate;' and where flint is so scarce, as in Scotland, hard slate may be used—for example, in North America.[6] I rather regard the slate weapons as amulets, or churinga, analogous to the very old and rare boomerang-shaped churinga of the Arunta (lizard totem) of Central Australia. Mr. Millar observes: 'They have all been saturated with oil or fat, as water does not adhere to them, but runs off as from a greasy surface.' Now the Australian churinga are very frequently rubbed with red ochre, and made greasy with 'hand grease'—a singular coincidence. Footmarks are among the sacred Australian rock-paintings with a legendary sense. They also occur, engraved on rock in Brittany, Ireland, on 'The Fairy Stone' (ilkinia) in Glenesk, and on 'The Witches' Stone' at Monzie, associated with cups and concentric circles.[7] These close analogies point all in one direction.

Meaningless in Europe, what meaning have these designs in Australia? Though certainty is impossible, I take it that they were first purely decorative, before the mythical and symbolical meaning was read into them by the savages. They occur on the mystic 'bull-roarers' of Central Queensland, but I do not learn that in Queensland the circles and so on are interpreted or deciphered as among the Arunta.[8] Still, they occur here in a religious connection—the bull-roarer being swung at the mysteries—and they are carved on trees at mysteries held far south in New South Wales.[9] But even in Central Australia the markings sometimes occur as purely decorative, on one rock or other object, while on others they are sacred, and are interpreted as records of legends,[10] according to Spencer and Gillen. There are 'ordinary rock-paintings,' and certain other drawings, in many cases not distinguishable from some of the first series, so far as their form is concerned, but belonging to a class all of which are spoken of as churinga ilkinia, and are regarded as sacred because they are associated with totems. Each local totemic group has certain of these specially belonging to the group, and in very many cases preserved on rock-surfaces in spots which are strictly tabu to the women, children, and uninitiated men.' One of the commonest I represents a snake coming out of a hole in a rock,' which the wriggle out of the cup in our circle-marked stones would stand for fairly well. Some designs are only 'play-work;' others exactly similar, on another spot, have a definite meaning. The meaning is read, where the spot is sacred ground. The concentric circles are 'believed, on good ground, to have been derived from an original spiral.' 'It is much more easy to imagine a series of concentric circles originating out of a spiral than to imagine a spiral originating out of a series of concentric circles.' In this country the spiral seems to be later than the circle.

These devices not only occur on fixed rocks and portable churinga, they are also painted on the bodies of boys when initiated in the mysteries: 'concentric circles with radiating lines preponderate.'

In Mr. Haddon's 'Decorative Art of British New Guinea' he describes designs of concentric circles and spirals which are clearly derivatives of drawings of the human face.[11] Thus our concentric circles and spirals may, in the last resort, have been derived from drawings of the human face, though diablement changés en route.

What, then, however we interpret the origin, decorative or symbolic, of the sacred designs, is their significance as understood by the Arunta of Central Australia at the present time?
