Fractals in African Art

On the right is a Bamana headdress.
A qualitatitative comparison to (three stages of) a fractal tree is obvious.
A closer look - measuring the lengths of successive branches and computing their ratios - reveals the scaling is not quantitative.
The main branch has length about 1.4.
The secondary branches have length about 1.25.
The tertiary branches has length about 0.8.
So secondary/main = 0.9
and tertiary/secondary = 0.65
Of course, these measurements have some uncertainties, but still, the ratios appear different.
