In Search of Lost Time (French: À la recherche du temps perdu), first translated into English as Remembrance of Things Past, and sometimes referred to in French as La Recherche (The Search), is a novel in seven volumes by French author Marcel Proust. This early 20th-century work is his most prominent, known both for its length and its theme of involuntary memory. The most famous example of this is the "episode of the madeleine", which occurs early in the first volume.
