Chapter Thirty-four: of a certain religious man, that at his death saw the Prophets.
For a certain religious man of my Monastery, that lived a virtuous life, dying some four years since, saw at the very time of his departure (as other religious men do report, that were present) the Prophet Jonas, Ezechiel, and Daniel, and by their names called them his Lords, saying that they were come unto him: and as he was bowing his head downward to them for reverence, he gave up the ghost: whereby we perceive what perfect knowledge shall be in that immortal life, when as this man, being yet in corruptible flesh, knew the Prophets whom he never saw.
