That's the profound difference between your place and mine.
You had a thousand+ years of medieval times. Royalty, all that stuff.
Your chalcolithic swiftly slid into the bronze age then the iron age.
North America jumped, in a few decades, from Neolithic to the Iron Age with hand writing and printed books. Maybe it's more prevalent in the Pacific Northwest but the Neolithic is all around me in this day and time. Hunting, bulk fishing, arts, crafts and carvings, summer tipi and winter pit houses in the interior and huge cedar plank houses on the coast. All the kinds of poles are still carved, so are the 40' - 60' ocean cedar canoes.
The oral histories which record events of 15,000 years ago (fact) are entrusted to a tribal story teller. Trained from childhood, the kid with the aptitude shouldered to burdens. I met one of them this year. Stunning experience.
