Very interesting, Dave. His romance with Elizabeth Throckmorton (Abbie Cornish) is dramatised in Elizabeth: The Golden Age. It is slightly inaccurate, but certainly worth watching.
I suppose there wouldn’t be much else to do, if you were a prisoner in The Tower, glad to see that he used his time there wisely with writing. The cynicism in his work is quite self-explanatory when we know the situation that Raleigh was in.
