"Who ever can be trusted? woe is me!

  All false and cruel well may be esteemed,

  If thou, Rogero, false and cruel be,

  That I so pious and so faithful deemed.

  What foul and felon act, what treachery,

  Was ever yet by tragic poet dreamed,

  But will fall short of thine, if thou wilt set

  The sum of my desert, against thy debts?
