THAT’S my last Duchess painted on the wall,
The Duke knows the difference between the living Duchess and her painting – but he doesn’t see it as much of a difference. It’s startling that he brings up the unusual circumstances of his previous wife’s death at the beginning of this conversation with a servant of the family he wants to marry into next. He’s a little bit obsessive to say the least.

as if she ranked
The Duke can’t believe that anyone would fail to understand that the most important thing in the universe is having an old family name. Again, this isn’t exactly insanity, but it is an extremely narrow-minded attitude toward values.

OK, at this point, we’re really starting to wonder about the Duke’s sanity. "Disgust" is a bizarrely strong and inappropriate word to use to describe your reaction to someone smiling when they ride their white mule. If the Duke is this inappropriate with his word choice, we have to wonder about the other ways in which he is inappropriate.
