In chapter 5 of Mary Shelley's "Frankenstein", Victor completes his project of giving live to a dead creature made of pieces of different corpses.This happens after months of study and obssession with unveiling the secret of life. Moreover, the creature comes to life during a stormy night.
This event signals the relationship the Romantics had with the supernatural. Traditional ideas of science and logical thought from the Enlightenment were vanishing as writers were engaging in new ways to thing and approach the world, and this was reflected in Victor's approach to new supernatural ideas that go beyond traditional scientific thought. The coming to life of the monster is clearly an embodiment of the supernatural, as is the fact that he comes to life with thunder and lightning (another supernatural phenomena used by romantics along with fog, fire or spirits).
