46．“Though his fair daughter’s self, as I avowed

At starting, is my object. Nay, we’ll go

Together down, sir. Notice Neptune, though,

Taming a sea horse, though a rarity,

Which Claus of Innsbruck cast in bronze for me! ”

The lines above are taken from Robert Browning’s “My Last Duchess.” Taking the whole poem into consideration, what kind of person do you think the duke is?
