Dreadlesse (said he) that shall I soone declare:
2 It was complaind, that thou hadst done great tort
Vnto an aged woman, poore and bare,
4 And thralled her in chaines with strong effort,
Voide of all succour and needfull comfort:
6 That ill beseemes thee, such as I thee see,
To worke such shame. Therefore I thee exhort,
8 To chaunge thy will, and set +Occasion+ free,
And to her captiue sonne yield his first libertee.
