Mirror+of+Erised

The Mirror of Erised is first seen in Harry Potter and the Philosopher's Stone. Harry uses the mirror to obtain the Philosopher's Stone.

The Mirror shows the person standing infront of it their desires. Around the edge of the mirror is an inscription "//Erised stra ehru oyt ube cafru oyt on wohsi//". Reversing and rearranging the spaces on the inscription produces: //i show not your face but your heart's desire.//
