Who hath herd of suche crueltye before

Who hath herd of suche crueltye before ?
That when my plaint remembred her my woo
That caused it; she, cruell more and more,
Wisshed eche stitche, as she did sit and soo,
Had prykt myn hert for to encrese my sore.
And, as I thinck, she thought it had ben so :
For as she thought : " This is his hert in dede " :
She pricked herd, and made herself to blede.
