Numquam enim audiendi quod aliquis monachus super puerum incubuisset, quin statim post ipsum surrexisset puer.

'There was a man living on the borders of Burgundy who asked him to come and heal his son. We went, and found the son dead. Dom Bernard ordered his body to be carried into a private room, turned everyone out, threw himself upon the boy, prayed, and got up again: but the boy did not get up; he lay there dead.' 'Then he was the most unlucky of monks,' said I; 'I have heard before now of a monk throwing himself upon a boy, but always, when the monk got up, the boy promptly got up too.'
