Relations to Frankenstein
Mary Shelley's fascination for galvanism and the idea of life arising from death is apparent throughout Frankenstein. We first see this passion in a quote in the preface:
"I saw the hideous phantasm of a man stretched out, and then, on the working of some powerful engine, show signs of life..."
this draws a parallel with how Victor Frankenstein gave the secret of life to the creature. "I collected the instruments of life around me, that I might infuse a spark of being into the lifeless thing that lay at my feet."
The anatomy and physical appearance of the creature is quite significant. He is described as a creature or a monster with "dull, yellow eyes," and pale see through-like skin, and has a gigantic stature. He is not human, and he is not seen as such. He has a hideous appearance, and people flee when they behold him. This adds to the fearful tone of the book and gothic theme.
The creature's existence also relates to the phrenology of the time period. The creature is not the dumb, zombie-like monster that society has now made him out to be. In the book, Victor Frankenstein created an intelligent being capable of reason, emotion, and persuasion. We see evidence of this when the creature learns the language of the DeLacey family and how convincing he is when he persuades Victor to create a second companion.
