Final answer:
Mistress Hibbens refers to the Devil when offering to introduce Dimmesdale to 'yonder potentate you wot of' in 'The Scarlet Letter.'
Step-by-step explanation:
When Mistress Hibbens offers to introduce Dimmesdale to "yonder potentate you wot of," she is referring to the Devil, the prince of darkness in Christian tradition. This interaction occurs in Nathaniel Hawthorne's novel "The Scarlet Letter," where Mistress Hibbens is known to be involved in witchcraft and is suggesting that she can introduce the minister, Dimmesdale, to the devil himself.
This is a reflection of the theme of sin and the exploration of the human conscience that Hawthorne focus on throughout the novel.
