Here take my picture; though I bid farewell
Thine, in my heart, where my soul dwells, shall dwell.
'Tis like me now, but I dead, 'twill be more
When we are shadows both, than 'twas before.
When weather-beaten I come back, my hand
Perhaps with rude oars torn, or sun beams tann'd,
My face and breast of haircloth, and my head
With care's rash sudden storms being o'erspread,
My body'a sack of bones, broken within,
And powder's blue stains scatter'd on my skin;
If rival fools tax thee to'have lov'd a man
So foul and coarse as, oh, I may seem then,
This shall say what I was, and thou shalt say,
This is in reference to gun powder. Donne’s speaker is warning his lover that there may be conflict: fights with pirates, or worse.
