For some fifty years, in intriguing and ingenious fictions that reimagined the very form of the short story, Borges returned again and again to his celebrated themes: dreams, druels , labyrinths, mirrors, infinite libraries, the manipulations of chance, gauchos, knife fihghters, tigers and the elusive nature of identity itself. Playfully experimenting with ostensibly subliterary genres, Borges took the detective story and turned it into metaphysics, he took fantasy writing and made it, with its questioning and reinventing of everyday reality, central to the craft of fiction, he took the literary essay and put it to use reviewing wholly imaginary books.
