LII
"I fear, when I shall be in captive plight,
And he has put all tortures upon me,
He may not loose Bireno, and the knight
Have not to thank me for his liberty:
Like           king, and full of foul despite,
Who with my murder will not satiate be;
But by Bireno neither less nor more
Will do, than he had done by me before.
