The grave of Charles Williams in an Oxford churchyard is marked by a stone bearing his name and the terse description: Poet, followed by the words, Under the Mercy.
Under the Mercy is a phrase that appears frequently in his writings, as it did in his conversation. He liked to refer to the Divinity by Its Attributes: the Mercy, the Protection, the Omnipotence. In his personal life he seemed always to be clinging to the faith that, balanced as he was upon the knife-edge of his Christian allegiance in the world of myth and magic that his passion-inflamed imagination had conjured up, he would find at last, in death if by no other route, the stillness of the Love of God. It was his wife, Michal, in one of those sudden flashes of crystal-clear insight of which she was not infrequently capable, who chose the inscription on the stone. Nothing could have been more appropriate.
