Samuel Taylor Coleridge

01'Kubla Khan' was written in a single opium-induced session in 1797; Coleridge claimed an interruption by 'a person from Porlock' broke the trance.
02By 1816 Coleridge was consuming up to two quarts of laudanum per week, documented in letters to his physician James Gillman.
03Wordsworth formally ended their friendship partly over Coleridge's unreliability — lectures cancelled, manuscripts undelivered, debts accumulated.

Coleridge wrote 'Kubla Khan' in an opium dream in 1797, then spent forty more years unable to quit — dictating, borrowing money, and theorizing consciousness while his doses climbed. Wordsworth eventually cut him off. The poem stayed unfinished.
