Over the door, however, there was one of strange and rather striking shape; it was [a painting] six or seven feet in length, and not more than a foot in height. It represented the Saviour just taken from the cross.
The prince glanced at it, but took no further notice. He moved on hastily, as though anxious to get out of the house. But Rogozhin suddenly stopped underneath the picture. […]
"Lev Nicolaevich," said Rogozhin, after a pause, during which the two walked along a little further, "I have long wished to ask you, do you believe in God?"
"How strangely you speak, and how odd you look!" said the other, involuntarily.
"I like looking at that picture," muttered Rogozhin, not noticing, apparently, that the prince had not answered his question.
"That picture! That picture!" cried Muishkin, struck by a sudden idea. "Why, a man could even lose his faith looking at that picture!"
"Lose it he does," agreed Rogozhin, unexpectedly. (2.4.1-10)
