So the one for wrong, the other strives for right,
 And each to deadly shame would drive his foe:
 The cruel steel so greedily doth bite
 In tender flesh, that streams of blood down flow,
 With which the arms, that erst so bright did show,
 Into a pure vermillion now are dyed:
 Great rue in all the gazers' hearts did grow,
 Seeing the gored wounds to gape so wide,
That victory they dare not wish to either side.
