Melville's career was marked by early success with South Sea adventure novels like Typee, followed by the commercial failure and later critical triumph of Moby-Dick. His work is characterized by its complex symbolism, philosophical depth, and rich, often difficult prose. He explored themes of obsession, fate, and the struggle between man and nature. After his literary fame faded during his lifetime, he worked as a customs inspector while writing poetry. It was only during the 'Melville Revival' of the 1920s that he was recognized as one of the most profound voices in American literature.
