John Dowland: Unquiet Thoughts, from The First Booke of Songes, 1597 (The Consort of Musicke)

Unquiet thoughts, your civil slaughter stint,
And wrap your wrongs within a pensive heart:
And you: my tongue that makes my mouth a mint,
And stamps my thoughts to coin them words by art,
Be still: for if you ever do the like
I’ll cut the string that makes the hammer strike.

But what can stay my thoughts they may not start,
Or put my tongue in durance for to die?
When as these eyes, the keys of mouth and heart,
Open the lock where all my love doth lie;
I’ll seal them up within their lids for ever:
So thought’s, and words, and looks shall die together.

How shall I gaze on my mistress’ eyes?
My thoughts must have some vent: else heart will break.
My tongue would rust as in my mouth it lies,
If eyes and thoughts were free, and that not speak.
Speak then, and tell the passions of desire;
Which turns mine eyes to floods, my thoughts to fire.
