But it behoves, ere more of these be said,

  I should awhile of Agramant discourse,

  Who had from that night's raging fire conveyed

  To Arles, the remnant of his scattered force:

  Since to unite his troops, and furnish aid

  And victual, 'twas a place of much resource,

  Seated upon a river, nigh the shore,

  With Spain in front and Africa before.
