Flicking through Malaga Bay’s post on Justinian’s Raging Bulls, I noticed an interesting diagram used by Clube and Napier showing various interpreted cometary shapes printed in the Chinese Mawangdui Silk Texts below, Figure 1)
But these are simply pictures of plasma instabilities similar to the global-wide occurrences of petroglyphs described by Peratt and others. Those have been provisionally dated to some 10,000 years ago purely on the basis that they must have been carved in the neolithic period or earlier; the evolutionary apriorism theory.
However the pictures above were recorded during the Han Dynasty, ~ -200 AD to +200 AD, which is near enough to the Roman Termination Event of 650 AD. This suggests the global petroglyphs carved on various rocks might have also been carved at the same time, recording the same celestial phenomena during the iron age, when iron tools were available to carve the petroglyphs but after the cometary destruction the various global civilisations.
Which puts the neolithic period to where it belongs, after the Roman Era.
And suggests the Australian Aboriginal Dreamtime period was also coincident with the Middle Dark Ages, 235 AD to 920 AD for which there are no archaeological strata but plenty of rock paintings often over the top of the vitrified Bradshaw rock art.
