Chapter Nine: of the soul of a certain anchoret.
A certain religious man, and one of great credit (at such time as I lived in the Monastery), told me that certain sailing from Sicily to Rome, as they were in the midst of the sea, beheld the soul of a certain servant of God carried to heaven, who had been an Anchoret in the land of Samnium. Landing afterward in the same place, and making enquiry of that thing, they understood that holy man to have departed this life upon that very day in which they saw his soul ascending to heaven.
