Intertextuality is my joy--at least it is with these two texts. Look at the section where Frankenstein meets the monster, in Chapter 10, and compare it to the semantic field of Paradise Lost.
He approached; his countenance bespoke bitter anguish, combined with disdain and malignity, while its unearthly ugliness rendered it almost too horrible for human eyes. But I scarcely observed this; rage and hatred had at first deprived me of utterance, and I recovered only to overwhelm him with words expressive of furious detestation and contempt.
“Devil,” I exclaimed, “do you dare approach me? and do not you fear the fierce vengeance of my arm wreaked on your miserable head? Begone, vile insect! or rather, stay, that I may trample you to dust! and, oh! that I could, with the extinction of your miserable existence, restore those victims whom you have so diabolically murdered!”
“I expected this reception,” said the dæmon. “All men hate the wretched; how, then, must I be hated, who am miserable beyond all living things! Yet you, my creator, detest and spurn me, thy creature, to whom thou art bound by ties only dissoluble by the annihilation of one of us. You purpose to kill me. How dare you sport thus with life? Do your duty towards me, and I will do mine towards you and the rest of mankind. If you will comply with my conditions, I will leave them and you at peace; but if you refuse, I will glut the maw of death, until it be satiated with the blood of your remaining friends.”
“Abhorred monster! fiend that thou art! the tortures of hell are too mild a vengeance for thy crimes. Wretched devil! you reproach me with your creation; come on, then, that I may extinguish the spark which I so negligently bestowed.”
Is't it interesting how Shelley seems to echo Milton to create her creator/rebel conflict?
