God marred the rash emprise, and from on high

  Sent down an angel, whose destroying sword

  A hundred thousand of that chivalry

  Slew, and to endless night condemned their lord.

  Emerging, next, from hellish caverns, fly

  These horrid harpies and assault his board;

  Which still pollute or waste the royal meat,

  Nor leave the monarch aught to drink or eat.
