Role in the BooksEdit



Relationships with Other CharactersEdit


Arithmancy is otherwise known as numerology, which is in fact a real subject. It involves the finding of magical properties of numbers.

In the Harry Potter world, numbers are often inscribed in places, such as tombs, pyramids, and monuments. These numbers supposedly have meaning, either hiding a secret message or protecting the site with a curse. Arithmancy, if applied correctly, allows the practitioner to interpret these findings.

Gringotts curse breakers are required to have sufficient knowledge of Arithmancy.
