A PREHISTORIC ROCK-SCULPTURE FROM THE NORTH- 
EASTERN TRANSVAAL. 
By C. Pijpek. 
(With Plate XII.) 
The stone, pictured herewith, was discovered by me in the Lijdenburg 
district, in the North-Eastern Transvaal, not far from the stones engraved 
with cup-and-ring markings, of which I gave a description in the * South 
African Journal of Science,' March-April, 1919. 
There can be no doubt that the circular " knob " is the handiwork of man; 
it is so very nearly circular, in fact as nearly circular as we can imagine it 
was possible to make it with crude stone implements only, without the help 
of compasses or similar instruments ; moreover, in the original the tool- 
marks are unmistakable. 
As the " moat " around the " knob " has, from length of time, once more 
assumed the colour of the original rock, this " j^iece of sculpture " must date 
from long, long ago. 
As far as I know, no similai- rock-sculpture has ever been described 
from South Africa, and this circumstance I think justifies the publication of 
this photo, even although it is at present impossible to say by whom this piece 
of work was executed or what it was intended to represent. It seems most 
likely, however, that it was meant to be an image of the sun ; is it possible 
that the semi-circular lines higher up on the rock were intended to represent 
the moon ?
