"I know not if thou knowest -- the stones know-- How by Troyano was thy father slain;
And yet Troyano's son, against his foe, Thou would'st defend, and keep from harm or stain Such vengeance upon him do'st thou bestow?
And do his vengers, as their meed obtain, That I, descended of his stock, should be The martyr of the mortal cruelty?"
