Antiquity to Classical again

I've been going through the subdivisions and, withough mentioning them individually, adding links to human ecology, Asian geography, foodstuffs, language, customs, education, particular governments, Abrahamic religion and Asiatic religion, and social types. I've also been going through and picking up references to cities. There aren't many as old as the early first millennium BC, but there is another one or two in each successive period. I'll be mostly relying on these to guide whether to subdivide particular nations, eventually. In roughly the late medieval period, I've made a few more connections of specific cities to specific nations, which is helping give them detail. The connections to Abrahamic and Asiatic religion are starting to give a reasonable outline sketch of their history.
