–The foyer to the Dambreuse residence has a red carpet (tapis rouge), Arnoux’s boutique has a green carpet (tapis vert).
–The foyer to the Dambreuse residence has a double stairway (escalier double), Arnoux’s boutique a “small stairway” (petit escalier).
–Both these spaces include porcelain objects, unspecified at Anroux’s boutique, at the Dambreuse residence “two porcelain globes”.
–The idea of “two” is frequently repeated in Sentimental Education. In the description of the Dambreuse foyer, it’s mentioned three times: the stairs, the globes, the strong boxes.
–The two strong boxes Frederic encounters in the “small room” of the Ambreuse house will make an important reappearance at the novel’s close.
–The idea of thin walls (first found in Frederic’s dorm room) will also make a reappearance.
–Description of Frederic’s room on the quai Napoleon has again the idea of two, [1.3.31].
–Like the Dambreuse residence, Arnoux’s “office” (an un-named room above the shop) has two candelabra… (The word two is repeated twice in this paragraph.) We also saw bronze objects at the Dambreuse’s (here a statue of Venus) and in the boutique downstairs. [1.4.39];
–Arnoux’s office, like the shop below it, has a curtained door (actually –two).
