Patrick Wyman—of the Tides of History podcast—just put out a new book, Lost Worlds, which is worth a read if this is your bag. The basic premise is that the way ancient history is typically taught, "that we moved linearly from foraging to farming, and then from country farmers to city-dwelling, tax-paying subjects of kings and emperors," is essentially wrong. He goes on:

>All of those developments occurred in an orderly sequence: First farming and village life arrived; then surpluses born of human achievement that created social inequality; then hierarchies with priests and chieftains at the top; then massive monuments, cities, states, and writing to keep track of it all. Geographically, the old story of those developments centered on the Fertile Crescent of western Asia, and to a lesser extent the Nile Valley of Egypt....

>That story is wrong in some respects and incomplete in far more.

It's a constant rise and fall, with innovations and cities/civilizations that both did and didn't succeed often equally valid and appropriate paths to take. Sounds kind of bog-standard, I guess, but it's rife with examples of "Oh yeah here's a 1,500 year-old city, but it was 7,000 years ago and then disappeared so you've never heard of it."
