[...] his back is fairly turned?
The pair of goodly palaces are burned,
The gardens ravaged, and your Guelf is drunk
A week with joy ; the next, his laughter sunk
In sobs of blood, for he found, some strange way,
Old Salinguerra back again; I say
Old Salinguerra in the town once more
Uprooting, overturning, flame before
Blood fetlock-high beneath him; Azzo fled;
Who escaped the carnage followed; then the dead
Were pushed aside from Salinguerra's throne.
He ruled once more Ferrara, all alone.
Till Azzo, stunned awhile, revived, would pounce;
Coupled with Boniface, like lynx and ounce.
