Voyage Beneath the Waves was published two years prior to Jules
Verne's Twenty Thousand Leagues Under the Sea. Verne, when he became aware
of Jules Rengade's serial version, felt obliged to write the magazine
editor to set the record straight--he'd developed the idea independently!
In fact, the influence was very much the other way around: although Rengade
had come up with the idea of an imaginary voyage of submarine exploration
separately, he'd modeled his narrative style on Verne's, thus producing
the first "Vernean" novel written by someone other than the
great man himself. This is the first fictional use of a man-made submersible
to explore the ocean depths--and it remains a very readable entry into
the then-new genre of science fiction.
