In the early centuries of the third millennium b.c., families measure boundaries and drive wooden stakes into the silt of the Mesopotamian basin. The air hangs thick and hot over the flat terrain. Men drag heavy stones and mix clay to build defensive perimeters against unknown neighbors. The relentless migration down from the highland ridges breeds deep physical exhaustion. Settling the alluvial plains provides the final consolation of a predictable grain harvest.
Seventy distinct clans disperse across the eastern Mediterranean and adjacent deserts. The sons of Japheth push north toward the maritime coasts. Hamitic tribes march south toward the harsh sands of Canaan and Egypt. Shem keeps his flocks near the eastern river valleys. They divide the soil to secure grazing rights and fresh water. Nimrod establishes the first geopolitical empire in Shinar. He lays the foundation for Uruk—a settlement that will later construct massive ziggurats from baked clay. The Maker of All Things watches men scatter to form the Gentile borders. Survival demands vast distance between competing brothers.

Good fences and deep wells keep blood relations from turning into blood enemies.
The descendants of Noah abandoned their temporary tents to construct permanent cities of brick and asphalt. Their initial property lines forged the rigid geographical grid for the known world.
