Edna St. Vincent Millay (1892–1950).
This sonnet first appeared in ‘Renascence and Other Poems’. (1917). It’s a version of the Bluebeard story., perhaps best known in Perrault's tale from the 17th century.
By the twenty-first century the rewritten fairy tale has become a genre of its own. Angela Carter aside, few attempts are as interesting as Millay's original use of this story.
