Title: Defensive Magical Theory

When Defensive Magical Theory appears on Harry and Ron’s book list for the new school year, Fred and George Weasley reckon Dumbledore must have found a new Defence Against the Dark Arts teacher for Hogwarts. Well, the school certainly needs one: in recent years Defense Against the Dark Arts teachers have been sacked, died, had their memory erased, and have been locked in a trunk for nine months. It’s not a great advertisement for the school. I was a kindergarten teacher for a while and that was really quite exhausting…. but luckily no one erased my memory. At least, I don’t think so. I’m fairly sure I was never locked in a trunk either.

The new teacher is the deeply unpleasant Professor Umbrage whose idea of a lesson is to make the class read Defensive Magical Theory which is unreadably dull. Definitely no wands and no practicing spells.

Also featured in Order of the Phoenix is The Dream Oracle by Inigo Imago which Professor Trelawny feels they may be tested on in their OWLS Divination exams, and Asiatic Anti-Venoms which Harry reads in the library in search of answers for his Potions homework.

In the Room of Requirement, where Harry sets up a class to teach his schoolmates ways to defend themselves against the Dark Arts, Hermione is thrilled to find a large selection of helpful books including: A Compendium of Common Curses and their Counter Actions;

The Dark Arts Outsmarted;

Self-Defensive Spellwork;

and Jinxes for the Jinxed. Which Hermione begins to read at once. Because you never know.

For Christmas Sirius and Lupin give Harry Practical Defensive Magic and its Use Against the Dark Arts, in several volumes, it has moving coloured illustrations of all the counter-jinxes and hexes it describes which sounds a lot more useful than Umbrage’s lessons, and Harry gives Hermione a copy of New Theory of Numerology.

Also mentioned in Harry Potter and the Order of the Phoenix is Miranda Goshawk’s The Standard Book of Spells, Grade 5

Magical Hieroglyphs and Logograms,

Spellman’s Syllabary, Intermediate Trandfiguration and 

Achievements in Charming. Needless to say, most of these books are in Hermione’s book bag.
