The Grail first appears in Chrétien de Troyes twelfth-century romance Perceval, where it is a dish in the service of an other. But over the next few decades of Grail literature, during a time R. I. Moore has identified as the "formation of a persecuting society," this Grail becomes the Holy Grail and gets used to discriminate between peoples. We will explore this change with the help of Emmanuel Levinas who created an Ethics of the Other.
