Another Country by James Baldwin:
They reached the first of a labyrinthine series of rooms, shifting and crackling with groups of people, with bright paintings above and around them, and stretching into the far distance, like tombstones with unreadable inscriptions. The people moved in waves, like tourists in a foreign graveyard. Occasionally, a single mourner, dreaming of some vanished relationship, stood alone in adoration or revery before a massive memorial—but they mainly evinced, moving restlessly here and there, the democratic gaiety. Cass and Eric moved in some panic through this crowd, trying to find a quieter place; through fields of French impressionists and cubists and cacophonous modern masters, into a smaller room dominated by an enormous painting, executed, principally, in red, before which two students, a girl and a boy, stood holding hands.
