Answer:
Sibyl Vane knows Dorian Gray by the name of "Prince Charming".
Step-by-step explanation:
Dorian and Sibyl are characters in Oscar Wilde's novel "The Picture of Dorian Gray."
Dorian was a normal, handsome young man. Because of a poisonous friendship, Dorian begins to pay attention to his own beauty as well as the fact that it will, one day, fade away. Afraid of growing old and losing his beauty, Dorian sells his soul. Every sin he commits and every trait of ageing now marks his picture, but not his body. Dorian looks young and beautiful, but the painting in his attic looks monstrous, evil. Sibyl is a girl who falls in love with Dorian. She calls him "Prince Charming" and is, at first, unaware of the horrors surrounding him. Unfortunately, as often happens with those who get involved with him, Sybil ends up affected by Dorian's cold-heartedness and sinful lifestyle. She kills herself by drinking poison.
