  • "Whereas upon that pestilential but longed-for staircase to the old dressmaker's, since there was no other, no service stair in the building, one saw in the evening outside every door-mat in readiness for the morning round, on the splendid but despised staircase which Swann was now climbing, on either side of him, at different levels, before each anfractuosity made in its walls by the window of the porter's lodge or the entrance to a set of rooms, representing the departments of indoor service which they controlled and doing homage for them to the guests, a concierge, a major-domo, a steward (worthy men who spent the rest of the week in semi-independence in their own domains, dined there by themselves like small shop-keepers, and might to-morrow lapse to the bourgeois service of some successful doctor or industrial magnate), scrupulous in observing to the letter all the instructions they had been given before being allowed to don the brilliant livery which they wore only at rare intervals and in which they did not feel altogether at their ease, stood each in the arcade of his doorway with a pompous splendour tempered by democratic good-fellowship, like saints in their niches, while a gigantic usher, dressed in Swiss Guard fashion like the beadle in a church, struck the floor with his staff as each fresh arrival passed him."

  • "Within the boundaries of their domain, however, the radiant daughters of the sea were constantly turning round to smile up at the bearded tritons who clung to the anfractuosities of the cliff, or towards some aquatic demi-god whose skull was a polished stone on to which the tide had washed a smooth covering of seaweed, and his gaze a disc of rock crystal."

  • "Not only did I no longer feel the anxious dread of loneliness which had gripped my heart the first evening; I had no longer any need to fear its reawakening, nor to feel myself a homesick stranger in this land productive not only of chestnut-trees and tamarisks, but of friendships which from beginning to end of the route formed a long chain, interrupted like that of the blue hills, hidden here and there in the anfractuosity of the rock or behind the lime-trees of the avenue, but delegating at each stopping-place an amiable gentleman who came to punctuate my journey with a cordial handclasp, to prevent me from feeling its length, to offer if need be to continue it with me."
