What is the physic? The prayers?
I’ve always thought of it as being the reprieve – as if Hamlet’s NOT KILLING him were the medicine. But it’s not terribly logical having the medicine be NOT doing something. I suppose, in modern medicine, you can be prescribed some Not Doing. Don’t Work or Don’t Have Sex or Don’t Drink Grapefruit Juice – or something.
But this is a physic – not a prescription. A temporary cure of some kind – some kind of palliative medicine.
I think it’s the prayers. I think physic is Claudius’ prayers.
