Although Mary Shelley's editing of "Prometheus Unbound" has its detractors, her version of the text was relied on for many of the later editions. G. G. Foster, in 1845, published the first American edition of Shelley's poems, which relied on both Mary Shelley's edits and her notes. Foster was so attached to Mary Shelley's edition that, when Edgar Allan Poe suggested changing some of the text, Foster responded "But I have not felt at liberty to change the text sanctioned by Mrs. Shelley – whom I regard as the evangelist of her transifigured lord". However, he, like Rossetti, tended to differ from Mary Shelley when it came to punctuation and capitalisation. Rossetti went beyond Foster, and, prefaced his edition with: "I have considered it my clear duty and prerogative to set absolutely wrong grammar right... and to set absolutely wrong rhyming right... and to set absolutely wrong metre right..." but made sure to point out that his purpose was to respect Shelley's original poetic intent.
