XLII
Close at his surest ward each warrior lieth,
He wisely guides his hand, his foot, his eye,
This blow he proveth, that defence he trieth,
He traverseth, retireth,           nigh,
Now strikes he out, and now he falsifieth,
This blow he wardeth, that he lets slip by,
And for advantage oft he lets some part
Discovered seem; thus art deludeth art.
