Prometheus to be substantially discounted in preference to his own concerns for promoting his own version of an idealized consciousness of a society guided by the precepts of High British Romanticism and High British Idealism. "Frankenstein; or, the Modern Prometheus", written by Mary Shelley when she was 18, was published in 1818, two years before Percy Shelley's above mentioned play. It has endured as one of the most frequently revisited literary themes in twentieth century film and popular reception with few rivals for its sheer popularity among even established literary works of art. The primary theme is a parallel to the
Prometheus Unbound (Shelley) Este, requesting "The sheets of 'Prometheus Unbound,' which you will find numbered from one to twenty-six on the table of the pavilion." There is little other evidence as to when Shelley began "Prometheus Unbound" while he was living in Italy, but Shelley first mentions his progress in a letter to Thomas Love Peacock on 8 October 1818: "I have been writing – and indeed have just finished the first act of a lyrical and classical drama, to be called 'Prometheus Unbound'." Shelley stopped working on the poem following the death of his daughter Clara Everina Shelley on 24 September 1818.
