manifest, seeing Thou hast so willed I should lie on a dunghill, like
Job and Lazarus, whom Thou didst love so well. And Thou hast given me to
know how filthy straw is a soft and sweet pillow to the just man. And
Thou, dear Son of God, who didst descend into Hell, bless Thou the sleep
of Thy servant where he lies in the gloomy prison-house. Forasmuch as
men have robbed me of air and light, because I was steadfast to confess
the truth, deign to enlighten me with the glory of the everlasting
dayspring and feed me on the flames of Thy love, O living Truth, O Lord
my God!"

Thus prayed the holy man Giovanni with his lips. But in his heart he
remembered the sayings of the Adversary. He was troubled to the bottom
of his spirit, and in much trouble and anguish of mind he fell asleep.

And seeing the thought of the Adversary weighed heavy on his slumbers,
his sleep was not like the little child's lying on its mother's breast,
a gentle sleep of smiles and milk. And in his dreams he beheld a vast
wheel that shone with colours of living fire.

It was like those rose windows of flower-like brilliancy that glow over
the doors of Churches, the masterpieces of Gothic craftsmen, and display
in the translucent glass the history of the Virgin Mary and the glory of
the Prophets. But the secret of these rose windows is unknown to the
Tuscan artificer.

And this wheel was great and dazzling and brighter a thousandfold than
the best wrought of all the rose windows that ever were divided by
compass and painted with brush in the lands of the North. The Emperor
Charlemagne saw not the like the day he was crowned.
