For joying; for besides that he anew
Trusts to acquire Belgrade, and tower and town
Throughout the Bulgars' country to subdue,
He would by favours make the knight his own,
And hopes to rank him in his warlike crew:
Nor need he envy, guarded by his blade,
King Charles', Orlando's, or Rinaldo's aid.

Theodora was by other thoughts possest,
Whose son was killed by young Rogero's spear;
Which through his shoulders, entering at his breast,
Issued a palm's breadth in the stripling's rear;
Constantine's sister she, by grief opprest,
Fell down before him; and with many a tear
That dropt into her bosom, while she sued,
His heart with pity softened and subdued.

"I still before these feet will bow my knee,
Save on this felon, good my lord," (she cried)
"Who killed my son, to venge me thou agree,
Now that we have him in our hold; beside
That he thy nephew was, thou seest how thee
He loved; thou seest what feats upon thy side
That warrior wrought; thou seest if thou wilt blot

From the wide champaign, red with Grecian gore,
Bears that fell man; and like a reckless bird
Into the fowler's net hath made him soar;
That for short season, for revenge deferred,
My son may mourn upon the Stygian shore.
Give me, my lord, I pray, this cruel foe,
That by his torment I may soothe my woe."

So well she mourns; and in such moving wise

(Nor from before the emperor will arise,
Though he three times and four the dame has hent,
And to uplift by word and action tries)
That he is forced her wishes to content;
And thus, according to her prayer, commands
The Child to be delivered to her hands;

XIX
And, not therein his orders to delay,
They take the warrior of the unicorn
To cruel Theodora; but one day
Of respite has the knight: to have him torn
In quarters, yet alive; to rend and slay
Her prisoners publicly with shame and scorn,
Seems a poor pain; and he must undergo
Other unwonted and unmeasured woe.

At the commandment of that woman dread,
Chains on his neck and hands and feet they don;
And put him in a dungeon-cell, where thread
Of light was never by Apollo thrown:
He has a scanty mess of mouldy bread;
And sometimes is he left two days with none;
And one t
