Hi Yohann, Filiberto and all
Interesting intuitions! From both of you. (You must be smoking good stuff
).
The naive interpretation of coat of arms is indeed credible, including for the «lion and snake» or «deer and eagle» octagons.
The three interpretations of a «compass rose» on the rug also do ring a bell: This was about 100 years before any european-made compass, but surely one can find «stars» or «wheel spokes» in knight's armorials and similar motifs are also found in Central Asia for example. Here a detail of a flower (?) prominent both in the main field and in one border of the Pazyryk rug. No less!
Bon Dimanche.
