I'm reading one of the best-written books I've ever read :
The Lion and the Throne : the Life & Times of Sir Edward Coke, 1552-1764
by Catherine Drinker Bowen (author also of Miracle At Philadelphia, about the Constitutional Convention)
Coke was the young Roger Williams' employer & mentor. Basically a master & saint of the Law (vs. tyranny). A key element of English legal tradition : right of accused to fair trial, no matter who, no matter what.
Here are some interesting Bowen quotes about writing.
& how did I get to this? Thanks to ol' Ez, whose Cantos extoll Coke as one of the wisest of men. Highly ironic, since Pound's whole temper & personality (violent, arrogant, irascible, contemptuous, brave, foolhardy) would have set him amongst those noblemen full of contumely whom Coke, time & again, excellent legal hound that he was, sent to the scaffold.
