Click here to watch the YouTube video clip from The Prisoner of Azkaban where the Marauder’s Map of Hogwarts Castle is first introduced.
The map is presented to Harry by the Weasley twins Fred and George, who in their first year nicked it from the office of the very impopular school caretaker, Argus Filch. He in turn had confiscated it years before, from the makers of the map, the four Marauders who called themselves Moony, Wormtail, Padfoot and Prongs – all of whom we get to know more about before the end of the third book.
It was a map showing every detail of the Hogwarts castle and grounds. But the truly remarkable thing was the tiny ink dots moving around it, each labelled with a name in minuscule writing. (PoA 10)
The spell to open the map is: “I solemnly swear that I’m up to no good.” And to close it: “Mischief managed.” Which makes it go back to just a blank piece of parchment for the eyes of those who don’t know its secret.
The map is also put to use in the rest of the series. One of its really tricky qualities is that the little moving dots always show the true name of the person. Something which can be both helpful and deceitful in a world where wizards and witches sometimes use magic to take on someone else’s appearance…
The map is one of the magical objects that come to Harry as a sort of heritage from his father, although he is not aware of it at the time.
