Is there a reason why 39 should give a bad hair day and 32 nice curls?

What is the history behind guilloche patterns and do they have any significant use in math or physics beside that they are decorative and hard to forge used as watermarks?

Is the gordian knot a guilloche pattern, i Think i saw example doing a know using a Wheel in a Wheel.

Was the ancient fascination of guilloche patterns and knots sprung from some serious mathematical or physic ponderings, or was it just that they were decorative?

If I would be speculative i would say it could have something to do with schumann resonance, so is there a reason why 13 hz or 39 hz would mean a bad hairday and 32 hz nice curls?

I do understand the romans and greeks could hardly know this but yet, is there a Connection between schumann resonance and earthquakes?

I remember some fable about Tesla where he built some resonance machine that almost took down a whole cityblock.

But then again maybe it is not about schumann resonance.
But could it be moons orbital resonance? Ancient people pretty keen on periodicity of heavenly bodies, and because of that intermixed astrological systems?

So let me reformulate the question, could ancient people be aware of schumann resonance or orbital resonance?
