“This book offers a fascinating analysis of Jules Verne’s Nautilus, from its design and engineering details to its unique place in early submarine history. Lavishly illustrated and brimming with quotes from Twenty Thousand Leagues Under the Sea, it brings to life Captain Nemo’s iconic underwater vessel.”

Editor, Science Fiction Studies, and eminent Jules Verne scholar

The Nautilus ProjectThe Nautilus Cover explores the Nautilus—the submarine from Jules Verne’s fantastical novel 20,000 Leagues Under the Sea—owned and commanded by the legendary Captain Nemo. The Nautilus Project and its corresponding book, The Design and Construction of the Nautilus, examine the possibility of such a craft existing in the 19th century. The truth may surprise you.

Still can’t get enough of 20,000 Leagues Under the Sea? Check out Rage Runs Deep, a sister to the Nautilus Project, exploring Captain Nemo’s life before his debut in Jules Verne’s classic novel.
