My last duchess begins and ends with the speaker pointing to a work of art.in the poem art has a symbolic meaning relating to the late Duchess.
In “My Last Duchess” the duchess displeased the duke showing disgraceful behavior. He claims that she flirted with everyone and did not appreciate his “gift of nine-hundred-years-old name.” You realize that it was the duke himself that caused the Duchess’s early demise.
I hope it helps, Regards.
