MP as Posthumus Leonatus

When I was 16 or 17  I opened a book for it contained a play by Shakespeare I had never even heard of, Cymbeline. The first dialogue I ever read was Act V, Scene IV and it surely ensured that this play became one of my favourites, for it made me wonder how somebody could end up in such a mess - when I later read the entire play I realised that it was more than well deserved ;). Therefore here the beginning of that scene :

First Gaol. You shall not now be stol'n, you have locks upon you:
So graze as you find pasture.
Sec. Gaol.                           Ay, or a stomach.
                              [Exeunt Gaolers.

Post. Most welcome bondage! for thou art a way, 
I think, to liberty: yet am I better
Than one that's sick o' the gout; since he had rather
Groan so in perpetuity than be cured
By the sure physician, death, who is the key
To unbar these locks. My conscience, thou art fetter'd
More than my shanks and wrists: you good gods, give me
The penitent instrument to pick that bolt,
Then, free for ever! Is't enough I am sorry?
So children temporal fathers do appease;
Gods are more full of mercy. Must I repent?
I cannot do it better than in gyves,
Desired more than constrain'd: to satisfy,
If of freedom 'tis the main part, take
No stricter render of me than my all.
I know you are more clement than vile men,
Who of their broken debtors take a third,
A sixth, a tenth, letting them thrive  again
On their abatement: that's not my desire:
For Imogen's dear life take mine; and though
'Tis not so dear, yet 'tis a life; you coin'd it:
'Tween man and man they weigh not every stamp;
Though light, take pieces for figure's sake:
You rather mine, being yours: and so, great powers,
If you will take this audit, take this life,
And cancel these cold bonds. O Imogen!
I'll speak to thee in silence.
