First the actual White Lady...who is a man... Really hard to photograph and quite faint now. Many years of people spraying water, or even worse, wiping a wet cloth on the painting to make it brighter has made it fade faster than the other paintings...the price of celebrity!
In this one you want to note the human legs on the antelope. The interpretation is that it represent part of what was happening to the shaman as they were going into trance and were turning into animals. A lot is made of animal with human parts or the reverse humans with animal parts and the trance. I guess I believe that it is a valid interpretation for at least SOME of the paintings.
The famous Twyfelfontein lion (I've already posted a photo earlier) who has 5 toes on each foot clearly drawn and one additional "foot" also with five toes engraved at the end of its tail is considered to also be a trance relate animal representation with human parts. Definitely, from what I saw, I noticed that when ever animals have human parts they are legs, toes etc...extremities, so it could very well be related to a common factor like the way those people reached their trance and the resulting sensations associated with the process.
What are future archaeologists going to make of present time abstract paintings?
I love that zebra but in a photo that size it doesn't show well.
