When Jules Verne wrote his Twenty Thousand Leagues under the Sea, he envisioned his nautilus in a rather conical design, it sort of resembled are large cigar. Not a very fanciful design at all. Disney came along and redesigned the Nautilus and gave it Victorian aspect. Although many have taken to envisioning what the Nautilus could have looked like. Some of the designs were rather fanciful like Disney’s, however the Disney design became one of the most popular. You might have seen miniatures, and scale models using this very design.
However, there is Nautilus design in The League of Extraordinary Gentlemen that is even more fanciful than all others. It is big and ominous. It sports an orange livery and features several, what look like tentacles like a squid or octopus have. These tentacles do not seem to have any purpose except to give the vessel a frightful appearance. In addition, there is coat of arms of Captain Nemo, or should I say Prince Dakkar on the submarines conning tower and the vessel spouts water like a whale would from its blow hole.
