" PARSIFAL: I move only a little, yet already I seem to have gone far.
GURNEMANZ: You see, my son, here time turns into space.
(The whole landscape becomes indistinct. A forest ebbs out and a wall of rough rock ebbs in, through which can be seen a gateway. The two men pass through the gateway. What happened to the forest? The two men did not really move; they did not really go anywhere, and yet they are not now where they originally were. Here time turns into space. Wagner began Parsifal in 1845. He died in 1873, long before Hermann Minkowski postulated four-dimensional space-time (1908). The source-basis for Parsifal consisted of Celtic legends, and Wagner’s research into Buddhism for his never-written opera about the Buddha to be called The Victors (Die Sieger). Where did Richard Wagner get the notion that time could turn into space?)"
