Shuger's study of Measure to Measure offers a sweeping reinterpretation of English political thought in the aftermath of the Reformation, one that focuses not on the tension between Crown and Parliament but on the relation of the sacred to the state.
I'm writing my dissertation on the rhetoric of key Shakespeare plays (mainly Othello, Coriolanus and Measure for Measure), so I thought this might be relevant. And whilst I found a few things which I could use, overall this book was painfully dull (and that's coming from someone who is usually very interested in the Renaissance period!). There was just too much Promos and Cassandra (which I've never read and now really do not want to!). If you've read that too, then it might be worth a read, but otherwise it will seem so long and tedious!
