Lord Byron and William Wordsworth were both prominent figures in the Romantic movement, but they had very different perspectives and styles. Byron was known for his satirical and often provocative writing, while Wordsworth's work was more introspective and focused on nature and the human condition.
Wordsworth's preface to "The Thorn" (a poem in his collection "Lyrical Ballads") emphasized simplicity and the portrayal of rustic life, which Byron found to be overly provincial and limited in scope.
"Don Juan" is Byron’s epic satirical poem, and in its preface, Byron took the opportunity to critique Wordsworth’s poetic principles and the narrow focus he saw in Wordsworth's work. This preface serves as a counterpoint to Wordsworth's ideas about poetry and poetics as expressed in his introduction to "The Thorn."
