My Last Duchess - Robert Browning

That's my last Duchess painted on the wall,
Looking as if she were alive. I call
That piece a wonder, now: Fr Pandolf's hands
Worked busily a day, and there she stands.
Will't please you sit and look at her? I said
"Fr 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,
How such a glance came there; so, not the first
Are you to turn and ask thus. Sir, 'twas not
Her husband's presence only, called that spot
Of joy into the Duchess' cheek: perhaps
Fr Pandolf chanced to say "Her mantle laps
"Over my lady's wrist too much,'' or "Paint
"Must never hope to reproduce the faint
"Half-flush that dies along her throat:'' such stuff
Was courtesy, she thought, and cause enough
For calling up that spot of joy.
