Fyodor Dostoevsky,
The Brothers Karamazov — Part IV, Book XI, Chapter 10
(1880)
“ Ivan raised his head and smiled softly."He was afraid of you, of a dove like you. You are a 'pure cherub.' Dmitri calls you a cherub. Cherub!... the thunderous rapture of the seraphim. What are seraphim? Perhaps a whole constellation. But perhaps that constellation is only a chemical molecule. There's a constellation of the Lion and the Sun. Don't you know it?""Brother, sit down," said Alyosha in alarm. "For goodness' sake, sit down on the sofa! You are delirious; put your head on the pillow, that's right. Would you like a wet towel on your head? Perhaps it will do you good." ”
