Where are you getting this information?
(Asked by Fang and Inky)
What I wanted to do was use sources that were not only about this time period but were also from this time period. I always document (and often cross-check) my sources, so if you are wondering where a specific piece of information came from, ask and I'll find it for you.
In brief, the main sources
are...
