Wolf Hall is a now-immensely-well-known tale of a slice of Henry VIII’s reign; a period I know little about: we skimped it at school and it gets throroughly mythologised anyway. The chief hero is Cromwell (not Oliver) who is portrayed (correctly,as I understand it) as a brilliant administrator and generally competent chap; as to whether he was really nice underneath, I neither know nor care.
What is chiefly interesting is the playing out of certain grand themes in the period. It was part of the development of civilisation, really, a time when people, under pressure of necessity, realised that quite a lot they had thought was true, wasn’t. Which is to say, sorting out the role of church and sovereign, and the succession (and perhaps the influences of bankers over lords; but that is another matter). Which in both cases amounted to a de-mythologising, or a decline in the importance of religion.
