'Dorian Gray is the subject of a full-length portrait in oil by Basil Hallward, an artist who is impressed and infatuated by Dorian's beauty; he believes that Dorian’s beauty is responsible for the new mode in his art as a painter. Through Basil, Dorian meets Lord Henry Wotton, and he soon is enthralled by the aristocrat's hedonistic worldview: that beauty and sensual fulfilment are the only things worth pursuing in life.
Newly understanding that his beauty will fade, Dorian expresses the desire to sell his soul, to ensure that the picture, rather than he, will age and fade. The wish is granted, and Dorian pursues a libertine life of varied and amoral experiences, while staying young and beautiful; all the while his portrait ages and records every soul-corrupting sin' (Wikipedia)
