The original novel – titled Frankenstein; or, The Modern Prometheus – was by Mary Shelley. It was about a young scientist named Victor Frankenstein who created a creature that was a humanoid.
Over time though the story was distorted. The first distortion was the creature – not the creature maker – came to be called “Frankenstein.” The second distortion was the creature became a monster. The third distortion was that Frankenstein, now a monster, had a mind of his own. He could no longer be controlled by anyone – least of all by the one, by those, who originally created him.
Shelley’s novel, then, evolved. It became in time a morality tale. Beware the monster you make for someday it might, likely it will, turn on you.
