Ne ought it mote the noble Mayd auayle,
2 Ne slake the furie of her cruell flame,
But that she still did waste, and still did wayle,
4 That through long +languour+, and hart-burning brame
She shortly like a pyned ghost became,
6 Which long hath waited by the Stygian strond.
That when old Glauce saw, for feare least blame
8 Of her miscarriage should in her be fond,
She wist not how t'amend, nor how it to withstond.
