“Down on your knees! It is God’s angel comes! Down! Fold your hands! From now on you shall see 30 many such ministers in the high kingdoms. See how he scorns man’s tools: he needs no oars nor any other sail than his own wings to carry him between such distant shores. See how his pinions tower upon the air, 35 pointing to Heaven: they are eternal plumes and do not moult like feathers or human hair.”
