Who is the poet of Wide Sargasso Sea and Emma?

Firstly, the two pieces of literature I believe you're referring two are novels, not poems. The writers are therefore authorsnot poets. Secondly, the two novels were written by very two different authors, in two different centuries.Wide Sargasso Sea was written by Dominican-born author Jean Rhys in 1966. Emma was written by English author Jane Austen and published in 1819.
