Quote 37
When they entered, they found hanging upon the wall a splendid portrait of their master as they had last seen him, in all the wonder of his exquisite youth and beauty. Lying on the floor was a dead man, in evening dress, with a knife in his heart. He was withered, wrinkled, and loathsome of visage. It was not till they had examined the rings that they recognized who it was. (20.18)
Finally, Dorian's mask is lifted, and his true self is revealed – justice is served.
Quote 38
Suddenly there flashed across his mind what he had said in Basil Hallward's studio the day the picture had been finished. Yes, he remembered it perfectly. He had uttered a mad wish that he himself might remain young, and the portrait grow old; that his own beauty might be untarnished, and the face on the canvas bear the burden of his passions and his sins; that the painted image might be seared with the lines of suffering and thought, and that he might keep all the delicate bloom and loveliness of his then just conscious boyhood. Surely his wish had not been fulfilled? Such things were impossible. It seemed monstrous even to think of them. And, yet, there was the picture before him, with the touch of cruelty in the mouth. (7.29)
Dorian's moral transformation begins to demonstrate itself in the portrait for the first time here. At this early stage, it acts as a kind of conscience for him, and he realizes that he has terribly wronged Sibyl.
Quote 39
As he often remembered afterwards, and always with no small wonder, he found himself at first gazing at the portrait with a feeling of almost scientific interest. That such a change should have taken place was incredible to him. And yet it was a fact. Was there some subtle affinity between the chemical atoms that shaped themselves into form and colour on the canvas and the soul that was within him? Could it be that what that soul thought, they realized? -- that what it dreamed, they made true? Or was there some other, more terrible reason? He shuddered, and felt afraid, and, going back to the couch, lay there, gazing at the picture in sickened horror.
One thing, however, he felt that it had done for him. It had made him conscious how unjust, how cruel, he had been to Sibyl Vane. It was not too late to make reparation for that. She could still be his wife. His unreal and selfish love would yield to some higher influence, would be transformed into some nobler passion, and the portrait that Basil Hallward had painted of him would be a guide to him through life, would be to him what holiness is to some, and conscience to others, and the fear of God to us all. There were opiates for remorse, drugs that could lull the moral sense to sleep. But here was a visible symbol of the degradation of sin. Here was an ever-present sign of the ruin men brought upon their souls. (8.10-11)
The transformation evident here isn't just in Dorian's portrait – it's in his attitude. Already, he's adopted the pseudo-scientific coldness of Lord Henry, even while pondering this mystery of his own corruption. We have to wonder if it's already too late for Dorian, even at this early stage.
