LEt not one sparke of filthy lustfull fyre
breake out, that may her sacred peace molest:
ne one light glance of sensuall desyre:
Attempt to work her gentle mindes vnrest.
But pure affections bred in spotlesse brest,
& modest thoughts breathd fro[m] wel te[m]pred sprites
goe visit her in her bowre of rest,
accompanyde with angelick delightes.
There fill your selfe with those most ioyous sights,
the which my selfe could neuer yet attayne:
but speake no word to her of these sad plights,
which her too constant stiffenesse doth constrayn.
Onely behold her rare perfection,
and blesse your fortunes fayre election.
Edmund Spenser
