Shelley incorporated a number of different sources into her work, one of which was the Promethean myth from Ovid. The influence of John Milton's Paradise Lost, and Samuel Taylor Coleridge's The Rime of the Ancient Mariner, are also clearly evident within the novel. Also, both Shelleys had read William Thomas Beckford's Gothic novel Vathek. Frankenstein also contains multiple references to her mother, Mary Wollstonecraft, and her major work A Vindication of the Rights of Woman which discusses the lack of equal education for males and females. The inclusion of her mother's ideas in her work is also related to the theme of creation and motherhood in the novel. Mary is likely to have acquired some ideas for Frankenstein's character from Humphry Davy's book Elements of Chemical Philosophy in which he had written that "science has...bestowed upon man powers which may be called creative; which have enabled him to change and modify the beings around him...".
