Though I can hardly compete with the fabulous entries already there, I really love the old tongue and couldn't stop myself from having go at it:

Sonnet to my Goddess

Thou hast my heart with subtlety enthralled,
My want no longer other than thy will;
Ask of me forth what once me so appalled,
I will do willingly thus and be still.
Thou hast, with alabaster skin and grace,
Mark'd me as thine for all eternity;
Drawn streams of hot tears on thy servants face,
And dried them off with joy of humblety.
Thy bonds hold steadfast me both day and night,
With promises of mine dark secrets these;
So ask not to release me from my plight,
And I will grateful ever aim to please,
For no less thou, a goddess, hast deserved,
But be forever worshipped and well served.
