    The spiral is quite common in petroglyphs from all over the world. Could that be a depiction of a sound wave?  When you see the figure, usually what you see with it, often looks like dancing and/or ceremonial dress.

    Just a thought.

    My second doctorate was in petroglyphs. The spiral in this case is not a sound wave, but rather a corn maze, something that lives on today as a fiendish form of "entertainment" in pumpkin patches. The origin of the corn maze was as a last-resort way to confuse an enemy invader and provide a hiding place. In the petroglyph pictured, we see a warrior whose shield has already been shot with several arrows by an advancing enemy. The hourglass at the upper right is a symbol that this warrior's time is almost up unless he can buy the 3 required tickets (cash only, no debit/credit cards), politely jump the line in front of the family in matching Moana costumes, and make it into the maze. Once inside, the enemy in hot pursuit will become lost, and likely starve to death as they wander in the corn. The enemy can even be dispatched in a cruel manner by catapulting paper cups of over-priced lukewarm sugar-free cocoa from a mix into the maze. 

    It is a tedious and terrible way to go. Ask me how I know this...

    Well gosh Scott, you' getting all warrior with me.LOL   
    Of course, your interpretation hangs on whether they could make glass, or an hourglass a million years ago!   Also the maze idea is a valid one, unfortunately, not as a circle as all paths lead back to the entrance. No getting lost there.
    My interpretation, is it's a sound wave at 5cps created with the trumpet he is holding, that splits and levitates rocks.

    I'm going to change that from trumpet to sonic tuning fork.
    Check out what a sonic tuning fork looks like.  sonic tuning fork, acoustic levitation

    Ah, yes, the over-priced lukewarm sugarfree cocoa ploy ... but actually, putting sugar in it can be nearly as fatal. I read about two shipwrecks, where the crews had to wait a long time for rescue. One had only drinking water and no food. They lasted a good long time, were rescued, and lived to tell the tale. The other crew had molasses on board, and no other food. They were dead in a couple of weeks.

    Ripples in a pond when something is thrown in? Annular rings in a tree stump? Lots of spirals in nature -- a snail shell. Would they know that sound spreads in waves? We don't hear them in steady sounds (too fast), we just hear beats when there is an interference pattern between two slightly different frequencies.
