to earth down hew,
And thy weak armies which too feeble been
To scale again these walls reinforced new,
And fainting lie dispersed on the green,
Shall take new strength new courage at his view,
The high-built towers, the eastern squadrons all,
Shall conquered be, shall fly, shall die, shall fall."

He held his peace; and Godfrey answered so:
"Oh, how his presence would recomfort me!
You that man's hidden thoughts perceive and know:
If I say truth, or if I love him, see.

Your messengers direct can to that part,
Where of the prince they shall hear certain news,
And learn the way, the manner, and the art
To bring him back to these thy warlike crews,
That all thy soldiers, wandered and misgone,
Heaven may unite again and join in one.

"But this conclusion shall my speeches end:
Know that his blood shall mixed be with thine,
Whence barons bold and worthies shall descend,
That many great exploits shall bring to fine."
This said, he vanished from his sleeping friend,
Like smoke in wind, or mist in Titan's shine;
Sleep fled likewise, and in his troubled thought,
With wonder, pleasure; joy, with marvel fought.

The duke looked up, and saw the azure sky
With argent beams of silver morning spread,
And started up, for praise axed virtue lie
In toil and travel, sin and shame in bed:
His arms he took,
