His boystrous club, so buried in the ground,
2 He could not rearen vp againe so light,
But that the knight him at +auantage+ found,
4 And whiles he stroue his combred clubbe to quight
Out of the earth, with blade all burning bright
6 He smote off his left arme, which like a blocke
Did fall to ground, depriu'd of natiue might;
8 Large streames of bloud out of the truncked stocke
Forth gushed, like fresh water streame from riuen rocke.
