Here again

I've never actually quit working on the Sapience Knowledge Base, but it has been a while since I've reported on on it here. I hope to have a new round of updates posted online in a day or two.
I've added substantially to the section on prehistory and a fair amount of new content to antiquity. I note that there are still considerable discrepancies in various ancient chronologies, so there is even now not a single chronology of the ancient world that is accepted as having a sound basis by scholars. Since biblical archaeology falls within this period, there are still major problems reconciling the Biblical account with accounts from other nations. I find this frustrating.
More recently, I'm starting to work backward through the classical and medieval periods for some of the currently most populous nations, and into the 19th century for those same ones. I;ve beenun using a mental analogy of the aids to a subject as tools for investigating it, and I keep finding that my tools aren't quite sharp enough. The list of nations is, for now, about the sharpest and most useful of them.
