Perhaps it was a bird; but when or where

  Another bird resembling this was seen

  I know not, I, nor have I any where,

  Except in Turpin, heard that such has been.

  Hence that it was a fiend, to upper air

  Evoked from depths of nether hell I ween;

  Which Malagigi raised by magic sleight,

  That so he might disturb the champions' fight.
