A Magical Theory Question

[danajsparks.livejournal.com]

In order to perform most spells, wizards and witches must speak or think a particular incantation and wave their wands, often using specific movements. Different combinations of incantations and wand movements will have different magical effects.

I've long believed that all of the incantations and wand waving involved in spell-casting are merely focusing techniques. In other words, while the words and movements help to center one's attention upon a specific spell, it is ultimately the caster's intent which produces the desired results. However, I now realize that there is at least one instance of spell-casting in canon that defies this reasoning. It is the case of Harry casting Sectumsempra upon Draco in HBP. This has undoubtedly been discussed elsewhere before, but it is a new conundrum for me.

Harry finds the incantation for Sectumsempra in the Prince's potions book at the beginning of chapter 21 of HBP.

He had just found an incantation “Sectumsempra!" scrawled in a margin above the intriguing words "For enemies," and was itching to try it out, but thought it best not to in front of Hermione. Instead, he surreptitiously folded down the corner of the page.

There are no accompanying directions for how to wave one's wand to cast the spell, nor is there any description of what the spell is supposed to do.

Harry casts Sectumsempra for the first time in response to Draco's attempted Cruciatus Curse in chapter 24.

"SECTUMSEMPRA!" bellowed Harry from the floor, waving his wand wildly.

Blood spurted from Malfoy's face and chest as though he had been slashed with an invisible sword. He staggered backward and collapsed onto the waterlogged floor with a great splash, his wand falling from his limp right hand.

If Harry had ever studied Latin, he would have known that "sectum sempra" means something like "always cuts" or, as Whitehound put it, "sever forever." But he never learned Latin, and so he didn't know beforehand what the effects of the spell would be.

"I didn't mean it to happen," said Harry at once. His voice echoed in the cold, watery space. "I didn't know what that spell did."

Setting aside Harry's deplorable behavior in casting an unknown spell designed "for enemies," what does it mean magically that shouting "Sectumsempra!" produced the result of slicing Draco open, even though Harry had no specific thought behind the spell? If Harry didn't know what Sectumsempra would do, then who or what did know? Who or what processed the incantation of "Sectumsempra" and interpreted its meaning to be "sever forever," if it wasn't Harry's brain?

Was it Harry's wand? Could wands be something like magical computers that are programmed to interpret Latin commands? Or was it magic itself? Is magic somehow sentient rather than simply a form of energy?

What are you thoughts?

Snape's scars

[terri-testing.livejournal.com]

"I'm surprised Snape didn't have scars on his forehead from banging his head repeatedly against the wall after every attempt to teach the kid anything."

Er--do you have any actual canon quotes to support that Snape DIDN'T sport such scars? I certainly can't come up with any....


Canon-compliant sarcastic comments, please!

(Goodness knows that there are enough that beg to be uttered.)

Hooked nose or bent inwards due to repeated impact?
