Sterilizing the Mariner II

I'm thinking that the Mariner's 1798 dialect is not only regionalized, localized, and "common," but--as Amanda suggests--Gothic. So maybe that's another wrench in the ... machinery? ... when thinking about reasons why Coleridge would streamline the Mariner's crunchy and vibrant linguistic peculiarities (it's a sunny day, give me a break on the adjectives!). Like, why would he take out the Gothic elements? How does the Gothic rub against or dismantle 2W's project of rusticity and commonality, and arguably up-to-the-momentness (I know there's a word for that). Like is the Gothic too passe, stuffy, and melodramatic for these revolutionary spirits?
