It makes sense that Mary was thinking of this myth when she wrote Frankenstein while living in London in 1818 at the age of 21.
It is said that Mary often read books as a child, at times beside the grave of her mother. She said herself that she loved to write stories as she was growing up, and through her father's company, she published her first poem, "Mounseer Nongtongpaw, when she was only ten years old.
In 1816 Mary wed Percy Shelly and soon after started writing her Frankenstein novel.
As a widow at the young age of 24, Mary supported herself and her son by writing more novels, including the science fiction story, The Last Man.
Mary Shelley died in 1851 at the age of 53. Her Frankenstein novel remains as popular as ever.
