@iinavpov@AspiringLuddite@icastico@NickEast@sciencefiction@writers@writingcommunity@writing I think the difference between Shelley (and her non-English counterparts) and earlier works is that Shelley moved from fantasy to science fiction. Today, traveling to the moon is fact, and before that it enjoyed some decades as science fiction. Prior to that, it was total fantasy.
Frankenstein goes into detail as to how the doctor builds the monster, and that's what makes it science fiction.
