The Mirror of Erised is a mirror, which, according to Albus Dumbledore, shows the "deepest, most desperate desire of our hearts." The name "Erised" is "desire" spelled backwards, as if reflected in a mirror. The happiest person in the world would look in the mirror and see a reflection of them, exactly as they were. The writing engraved on the frame of the mirror is supposedly in a foreign and probably dead language, but if you look closely it says "I show not your face but your heart's desire" backwards, with the spaces rearranged. Erised stra ehru oyt ube cafru oyt on wohsi.
