Swann’s Way, paragraph 19
But suppose my great aunt had been told that this Swann—who as the son of Swann was eminently qualified to be received by all the “belle bourgeoisie,” by the most esteemed bureaucrats and lawmakers of Paris (a privilege he apparently rather squandered)—had, as if in secret, an entirely different life; that after leaving our house in Paris, saying he was heading home to sleep, he’d scarcely get round the corner before setting off again and delivering himself to a salon that no broker or broker’s associate had ever set eyes on; to my aunt it would have seemed as extraordinary as for a more literate lady to think of being personally linked to Aristaeus, to understand that after having a chat with her, he’d dive down to the depths of the realms of Thetis, an empire hidden from mortal eyes where Virgil shows him received with open arms; or, to stick to an image more likely to come to her mind, as she’d seen it painted on our Combray petits-fours plates—to have hosted a dinner for Ali-Baba, who, once he finds himself alone, will enter the dazzling cave of unsuspected treasures.
