"Das Bildnis des Dorian Gray" by Oscar Wilde is a philosophical fiction and Gothic horror novel published in 1890. When a beautiful young man wishes that his portrait would age instead of himself, his desire becomes horrifyingly real. As Dorian pursues a life of hedonistic pleasure and immoral experiences, he remains eternally youthful while his painted image darkly transforms, recording every sin. This exploration of beauty, morality, and the corruption of the soul became Wilde's only novel and a cornerstone of Gothic literature.
