Edmund Spenser
Amoretti: Sonnet 32
The paynefull smith with force of fervent heat
    the hardest yron soone doth mollify:
    that with his heavy sledge he can it beat,
    and fashion to what he it list apply.
Yet cannot all these flames in which I fry,
    her hart more harde then yron soft awhit:
    ne all the playnts and prayers with which I
    doe beat on th'andvyle of her stubberne wit:
But still the more she fervent sees my fit:
    the more she frieseth in her wilfull pryde:
    and harder growes the harder she is smit,
    with all the playnts which to her be applyde.
What then remaines but I to ashes burne,
    and she to stones at length all frosen turne?
