The BBC documentary In Search of Shakespeare by Michael Wood is a little gem. I generally like Michael Wood's videos.
And when it comes to documentaries, the BBC is legendary.
It is in four parts. Here is part one.
"The wealth of another region excites their greed; and if it is weak, their lust for power as well. Nothing from the rising to the setting of the sun is enough for them. Among all others only they are compelled to attack the poor as well as the rich. Plunder, rape, and murder they falsely call empire; and where they make a desert, they call it peace."
Tacitus, Agricola
