Just remember when this book was written over 900 years ago. Many Americans still lived in animal skin tents and there were no white, or black skin "invaders" there. No Spaniards doing strange things to S. Americans, No states, no cities,, No Starbucks & definitely no MacDonalds, but Europe had big cities, proper trade routes, industry and had steel & iron. A good 400 years before the first recorded white, or Black man walked on the continents sward, or even it's beaches.
But books like this had been in Europe for sometime & scrolls for 1000 years at least and America didn't until about 400 years after this book was written.
