courser, sailing through the rack,
Who bore an armed knight upon his back.

V
Broad were his pinions, and of various hue;
Seated between, a knight the saddle pressed,
Clad in steel arms, which wide their radiance threw,
His wonderous course directed to the west:
There dropt among the mountains lost to view.
And this was, as that host informed his guest,
(And true the tale) a sorcerer, who made
Now farther, now more near, his frequent raid.

VI
"He, sometimes towering, soars into the skies;
Then seems, descending, but to skim the ground:
And of all beauteous women makes a prize,
Who, to their mischief, in these parts are found.
Hence, whether in their own or other's eyes,
Esteemed as fair, the wretched damsels round,
(And all in fact the felon plunders) hine;
As fearing of the sun to be descried.

VII
"A castle on the Pyrenean height
The necromancer keeps, the work of spell."
(The host relates) "of steel, so fair and bright,
All nature cannot match the wonderous shell.
There many cavaliers, to prove their might,
Have gone, but none returned the tale to tell.
So that I doubt, fair sir, the thief enthralls
Or slays whoever in the encounter falls."

The watchful maid attends to every thing,
Glad at her heart, and trusting to complete
(What she shall compass by the virtuous ring)
The downfall of the enchanter and his seat.
Then to the host -- "A guide I pray thee bring,
Who better knows than me the thief's retreat.
So burns my heart. (nor can I choose but go)
To strive in battle with this wizard foe."

IX
"It shall not need," exclaimed the dwarfish Moor,
"For I, myself, will serve you as a guide;
Who have the road set down, with other lore,
So that you shall rejoice with me to ride."
He meant the ring, but further hint forbore;
Lest dearly he the avowed should abide.
And she to him -- "Your guidance gives me pleasure."
Meaning by this she hoped to win his treasure.

What useful was to say, she said, and what
Might hurt her with the Saracen, concealed.
Well suited to her ends, the host had got
A palfrey, fitting for the road or field.
She bought the steed, and as Aurora shot
Her rosy rays, rode forth with spear and shield:
And maid and courier through a valley wind,
Brunello now before and now behind.

XI
From wood to wood, from mount to mountain hoar,
They clomb a summit, whic
