How The Marauder's Map Actually Works (Charm Explained)

如何从魔法角度解释活点地图的工作机制？

译者：兔子

Through seven novels, readers got to know the Wizarding World fairly well, learning about the most important events in its history, its most notable wizards and witches (both good and bad), and some of its most fascinating charms and objects, of which many made it to the movie saga. One of, if not the most popular object in the Harry Potter universe is the Marauder’s Map, introduced in Harry Potter and the Prisoner of Azkaban when Harry couldn’t join the rest on their trip to Hogsmeade, so Fred and George Weasley, who were in possession of the map, gave it to him so he could use one of Hogwarts’ secret passages that would lead him to Hogsmeade.

通过七部小说，读者对魔法世界有了相当深入的了解，包括它历史上许多重要的事件，著名的巫师(有好有坏)，以及一些迷人的咒语和物品，其中许多都在电影中有所呈现。

The Marauder’s Map was created by Remus Lupin (who went by the nickname Moony), Peter Pettigrew (Wormtail), Sirius Black (Padfoot), and James Potter (Prongs) when they were students at Hogwarts. The map shows every classroom, hallway, corner, and even the secret passages of Hogwarts and everyone in it, represented by a dot with their names, and it couldn’t be fooled by animagi (as seen with Pettigrew in Prisoner of Azkaban), Polyjuice Potions, or invisibility cloaks. Creating such an interesting and even dangerous map wasn’t easy, and it took the group years to finish it. However, a big question about the Marauder’s Map remains: how does it work?

活点地图是由莱姆斯·卢平（月亮脸）、小矮星彼得（虫尾巴）、小天狼星·布莱克（大脚板）和詹姆·波特（尖头叉子）在霍格沃茨上学时创作的。地图上显示了霍格沃茨的每一个教室、走廊、角落甚至是秘密通道和里面的每个人的位置，用一个点代表他们的名字，阿尼马吉，复方汤剂，或者隐形斗篷都瞒不过它（小矮星就是一个例子）。制作这样一幅有趣又危险的地图并不容易，需要花费数年时间才完成。然而，关于活点地图，还有一个大问题：它是如何工作的？

In order for the map to be able to track every single person in Hogwarts, including the ghosts, the Marauders used the Homonculous Charm, which once its cast onto a map, enables its possessor to track the movements of every person in the mapped area, and it's a strong enough charm to not be fooled by the aforementioned potions, cloaks, and more. Now, when it comes to how the Marauders knew every inch of Hogwarts so well, it was the result of teamwork: Sirius, Peter, and James’ animagi abilities enabled them to explore the castle grounds by night undetected, while the interior of the castle was mapped over time with the help of the invisibility cloak, which belonged to James at the time. In addition to the Homonculous Charm, the Marauder’s Map also had a special charm so it could repel and insult Severus Snape if he ever attempted to use it, as happened in Prisoner of Azkaban. Of course, the Marauder’s Map wasn’t perfect, and it couldn’t differentiate people with matching names and didn’t show unplottable rooms, such as the Room of Requirement.

为了让地图能够追踪霍格沃茨的每一个人，包括鬼魂在内，掠夺者组合使用了人迹咒，一旦它被施到一张地图上，它的持有者就能在地图上看到每一个人的行动，而且因为它的魔力足够强大，各种药剂、斗篷也逃不出它的法眼。现在,掠夺者们之所以能够知道霍格沃茨的每一寸土地,这需要归功于团队合作:小天狼星,彼得,詹姆的阿尼马吉的能力使他们能够在晚上探索霍格沃茨的外部。而詹姆则在隐形斗篷的帮助下探索内部。除了人迹咒之外，这种地图还有一种特殊的能力，如果西弗勒斯·斯内普使用它的话，它可以击退并侮辱他，《阿兹卡班的囚徒》中就发生了这样的情况。当然，这张地图并不完美，它不能显示人的名字，也不能显示出有求必应屋。

As interesting as the Homonculous Charm sounds, it’s one of those many charms from the Harry Potter universe that haven’t been properly explored, and there’s little information about it. As for the Marauder’s Map, it will continue to be one of the most popular and fascinating objects from the Wizarding World and one with an interesting story behind it, as it shows how advanced the magic of the group was, and it’s a shame that their talents were overlooked for so long.

这个咒语（人迹咒）听起来很有趣，但在哈利波特中，它几乎没有被提及，而且几乎没有留下相关的信息。至于掠夺者发明的活点地图，它将一直是巫师世界最受欢迎和最迷人的物品之一，它显示了这个小团队的魔法水平是多么高超，不得不说，他们的天赋被忽视了这么久是件很遗憾的事。
