But that lame Hag, still as abroad he strew
2 His wicked arrowes, gathered them againe,
And to him brought, fresh battell to renew:
4 Which he espying, cast her to restraine
From yielding succour to that cursed Swaine,
6 And her attaching, thought her hands to tye;
But soone as him dismounted on the plaine,
8 That other Hag did farre away espy
Binding her sister, she to him ran hastily.
