Here are two examples of some liberal translations/collaborations from/with Petrarch.

The long love that in my thought doth harbor
And in mine heart doth keep his residence,
Into my face presseth with bold pretence
And therein campeth, spreading his banner.
She that me learneth to love and suffer
And will that my trust and lust's negligence
Be reined by reason, shame, and reverence,
With his hardiness taketh displeasure.
Wherewithal unto the heart's forest he fleeth,
Leaving his enterprise with pain and cry,
And there him hideth and not appeareth.
What may I do when my master feareth
But in the field with him to live and die?
For good is the life ending faithfully.
Thomas Wyatt

Love that doth reign and live within my thought

And built his seat within my captive breast,

Clad in arms wherein with me he fought,

Oft in my face he doth his banner rest.

But she that taught me love and suffer pain,

My doubtful hope and eke my hot desire

With shamefaced look to shadow and refrain,

Her smiling grace converteth straight to ire.

And coward Love, then, to the heart apace

Taketh his flight, where he doth lurk and 'plain,

His purpose lost, and dare not show his face.

For my lord's guilt thus faultless bide I pain,

Yet from my lord shall not my foot remove,--

Sweet is the death that taketh end by love.

Henry Howard
