I think this picture symbolize a relationship : A man is standing to the left with straight back and bald head. He is annoyed. There's a barrier between him ( though there is an opening.... If he'd just face it, he'd see it ! ) and the curvy woman with pony-tail.... The nine kids sense the tension in the air....

The circles with a cross in them are called sun-wheels. This stone also has a lot of cupmarks. It's not known what they used to symbolize.
