english: Now, if these were random doodles or decorations, we would expect to see a lot more variation, but instead what we find are the same signs repeating across both space and time.
non_english: Ak by to boli len náhodné čmáranice či ozdoby, očakávali by sme väčšiu variabilitu, ale nachádzame naopak stále rovnaké znaky opakujúce sa v čase i priestore.
