Ah dearest Dame, (quoth then the Paynim bold,)
2 Pardon the errour of enraged wight,
Whom great griefe made forget the raines to hold
4 Of reasons rule, to see this recreant knight,
No knight, but treachour full of false despight
6 And shamefull treason, who through guile hath slayn
The prowest knight, that euer field did fight,
8 Euen stout Sans foy (O who can then refrayn?)
Whose shield he beares +renuerst+, the more to heape disdayn.
