"De Profundis" by Oscar Wilde is a letter written between January and March 1897 during his imprisonment in Reading Gaol. Addressed to his former lover Lord Alfred Douglas, the letter reflects on their tumultuous relationship and the extravagance that led to Wilde's conviction for gross indecency. In its pages, Wilde examines both Douglas's vanity and his own failings, then charts his spiritual transformation in prison and profound identification with Christ as a romantic artist. Written under strict supervision, the complete text wasn't published until decades after Wilde's death. (This is an automatically generated summary.)
