Poem about unequal marriage

My Last Duchess

That’s my last Duchess painted on the wall,
Looking as if she were alive. I call
That piece a wonder, now; Fra Pandolf’s hands
Worked busily a day, and there she stands.
Will’t please you sit and look at her? I said
“Fra Pandolf” by design, for never read
Strangers like you that pictured countenance,
The depth and passion of its earnest glance,
But to myself they turned (since none puts by
The curtain I have drawn for you, but I)
And seemed as they would ask me, if they durst,
