Fridge Brilliance: Why is there a Renaissance and an Industrial Revolution very similar to the ones in our timeline on a world without Europeans? Because these changes were not European. They were caused by people who were reincarnated, like the main characters in the book.
The writing style, in addition to updating its style across the centuries, also goes from describing the intimate details of foraging for food and a horse's reactions to glossing over war and socialist revolution within a few paragraphs. Why? Because these stories, too, are part of the Great Wheel, going inward to out across time, and the hub of a wheel describes a much smaller arc than the spokes or the rim.
