"My Last Duchess"

In "My Last Duchess" by Robert Browning, the speaker of the story is probably a real person that lived in that time frame, but obviously a Duke from the 17th-ish century. Some say that it was probably Alfonso II, the duke of Ferrara, whose wife died early in their marriage. The speaker obviously has an obsessive personalality, "Whene'er I passed her; but who passed without Much the same smile?" (44,45). He wished his wife sought after him abundantly and no-one else (showing a need to be worshipped). He is telling some other person probably someone who is affiliated with a prospect of a future wife, "That's my last Duchess painted on the wall, Looking as if she were alive. I call that peice a wonder[.]" (1,2,3) About this painting and gets side tracked, rambling on about his last wife's flaws: "too soon made glad" (22). This is obviously showing his frustation that all that he had done for his late wife, "My gift of a nine-hundred-years-old name" (33) Wasn't fully appreciated. It's obvious about his character, that this Duke has serious pride issues and it's assumed (by me) that this 'listener' would not be impressed.
