The novel

 * Angst? What Angst?: Dorian after Sybil's death.

 * Creepy Awesome: Dorian Gray.

 * Older Than Feudalism: If we take Dorian as Adam and Eve being tempted out of the Edenic innocence. And maybe Basil as Christ.
 * Older Than They Think:
 * Uniquely, occurring within the author's own writings -- a lot of the famous quotes from Wilde's comedies come from the novel, and one of the major characters in Lady Windermere's Fan is an Ascended Extra mentioned in passing in the novel.
 * Also, Wilde's great uncle, Charles Maturin, wrote the novel Melmot the Wanderer with the title character as a Flying Dutchman type who similarly keeps a portrait well-hidden, although not for Dorian's reason, only because it is dressed in antiquated clothing.
 * A meta-example is that the novel is somewhat inspired by the French book A Rebours, which is the "Yellow Book" Dorian is always reading.
 * The Penguin Classics edition's annotations note that the basis of the story, magical pictures that capture the soul or life essence of its subject's, are very old indeed. The Picture of Dorian Gray was a grim twist and deconstruction of the magical portrait trope, which would have been well known to Wilde's audience at the time of its writing.
 * The Svengali: Henry for Dorian.
 * Unusual Euphemism: "under the effect of his personality".
 * Values Dissonance: Homosexuality.
 * What Do You Mean Its Not Symbolic: Besides the eponymous painting that Hallward made of Dorian, he also painted several others of the lad in classical attitude -- such as Narcissus, the Grecian who was heartbreakingly beautiful, and cursed to fall in love with his own reflection and starve to death, while nymphs died for his love out of his sight.
 * The Woobie: Basil, who has to watch Dorian Gray, the love of his life and his greatest inspiration, descend deeper and deeper into corruption against his wishes and ultimately . Even The Soulless Dorian felt sorry for him.

Adaptations

 * Adaptational Attractiveness: Rugged, gawky young man Basil played by pretty men around 40 in most of the movies, like Ben Chaplin and Lowell Gilmore.
 * Fan Service: The 2009 Dorian/Basil kiss? Anyone?
 * Uncanny Valley: In the beginning of the 2009 film Dorian looked like he was animated.
 * WTH Costuming Department: The 1970 film (fittingly enough). Just look at that coat. Look at it!
