Written by Borges's mentor in the 1930s, but unpublished until after Fernandez's death, Museum is an "anti-novel," opening with more than fifty prologues—some philosophical, some outrageous—and ending with a novel featuring characters who are aware they're in a novel. Incredibly innovative, Macedonio deemed this "The First Good Novel," a counterpart to his very conventional "Last Bad Novel." A true masterpiece.
