We are indebted to Simon Critchley, writing in his consistently illuminating The Stone, for steering us towards a remarkable excerpt from the BBC series The Ascent of Man, presented by Dr. Jacob Bronowski.

We have long been troubled by that odd beseech from Cromwell, and finally decided to get to the bottom of it. From a fascinating study conducted by the estimable Philomantis, it appears that there has been a poorly digested text resulting in a King James Bible confusion between Christ’s tender mercy with its gut location.
