Geometric shapes in ancient rock art paintings
By Murray Bourne, 19 Apr 2016
In the video below, anthropologist Genevieve von Petzinger explains how certain symbols occur regularly in ancient rock art. Some of those cave markings are quite suggestive of mathematical symbols. This could be totally by accident, of course, but it's interesting to speculate beyond the main theme of her talk (that some aspects of written communication may be older than origninally thought) and consider the early development of mathematical and geometric symbols.
Some examples from the talk
Here are some screen shots from the video, showing:
- A circle,
- Numeral "1"
In this second image, we have what looks like rudimentary developmental symbols for:
- Multiply sign
Of course, such symbols are only "mathematical" if they were used in a mathematical way, but when you consider many of our current mathematical symbols were just borrowed from existing languages (many of the commonly used Greek letters, for example), it is possible that in the ancient world, symbols had a double meaning as well.
On with the video, entitled Why Are These 32 Symbols Found in Caves All Over Europe:
The related Guardian article, Did Stone Age cavemen talk to each other in symbols? mentions an intriguing commonly occurring pattern in cave art and jewellery:
II ^ III X II.
Perhaps this suggests rudimentary background symbols for the Roman numeral system, or perhaps they just found them "pretty". We tend to see what we want to see in unknown symbols.
