rome

the saying "all roads lead to roam" comes from the central hub of technology. it used to be true because back in ancient history they built all these different roads and all of them lead to rome. they built strong arched bridges, and mastered the concept of "running water" using aqueducts that, among other things, supplied public baths rivaling todays modern water facilities. at the height of its power in the 1st and 2nd centuries AD, the roman empire consisted of some 2.2 million square miles (5.7 million sq. km). 60 million people (or as much as 1/5 of the worlds population) claimed citizenship of rome and as many as 120 million people may have lived within its borders.
