This may be an allusion to Edgar Allan Poe's short story 'A Descent into the Maelström' (1841), a tale in which a man recounts how he survived a shipwreck and whirlpool.

It shares with Heart of Darkness a frame-narrative structure. Conrad considered the tale 'about as fine as anything of that kind can be - so authentic in detail that it might have been told by a sailor of sombre and poetical genius in the invention of the phantastic'.
