de Guermantes, almost at every name that was mentioned, exclaimed: “But he’s Oriane’s cousin!” with the sudden joy of a man who, lost in a forest, reads at the ends of a pair of arrows pointing in opposite directions on a metal plate, and followed by quite a low number of kilometres, the words: “Belvédère Casimir-Perier” and “Croix du Grand-Veneur,” and gathers from them that he is on the right road. On the other hand the word cousin was employed in a wholly different connection (which was here the exception to the prevailing rule) by the Turkish Ambassadress, who had come in after dinner. Devoured by social ambition and endowed with a real power of assimilating knowledge, she would pick up with equal facility the story of the Retreat of the Ten Thousand or the details of sexual perversion among birds. It would have been impossible to “stump” her on any of the most recent German publications, whether they dealt with political economy, mental aberrations, the various forms of onanism, or the philosophy of Epicurus.
