In other words, he did away with her, had her murdered, an easy thing for a man of his power at this epoch. First, however, he had her portrait painted. If he could not have the Duchess all to himself, he could at least have her picture entirely his own,
... since none puts by
The curtain I have drawn for you, but I.
He is thinking now of marrying again. Some Count snaps at the bait, the chance of this magnificent alliance for his daughter. Better to kill her with his own hand than to let her pass into the clutches of the Duke. The Duke's object in showing the envoy the picture is probably partly to get the opportunity of letting him know in time what he expects from his wife, so that when the messenger returns he may warn his young lady to keep her smiles under strict control.
Notice how Browning indicates the attitude of the envoy. First he is struck by the marvellous face of the Duchess—
The depth and passion of its earnest glance.
At last he essays a word in her defence,
Who'd stoop to blame
This sort of trifling?
and when the Duke has finished, he sits a little stupefied at the revelation that has been made, and still gazing at the picture. Even when the Duke rises he does not stir, and the latter has to rouse him, a little impatiently, "Will't please you rise?"
To me the most striking thing about this poem is its suggestiveness. It suggests infinitely more than it expresses. It expresses merely a fragment of a conversation; it suggests a whole tragedy.
Browning has, in these few lines, with delicate and curious skill, given us first the Renaissance atmosphere, a mixture of culture and refinement, delight in art and beauty, with immorality and crime; he has suggested to us the characters of the two actors in the drama from which this poem is but a fragment, the polished and cynical Duke and the girl who is sacrificed to his position and wealth; he has even suggested the mixture of deference, loathing, and fear with which the envoy listens to the Duke's description. There are anatomists who from a single bone of any animal will construct the whole skeleton; and so from this scrap which Browning has here given us we can construct the complete drama.
