Have you ever wondered why in so many stories (The Hobbit, Merlin, The Flight of Dragons, Aaron Gray and the Dragon War, Dragons of Pern) the dragons can talk, but in Harry Potter they are nothing but dumb and vicious animals? Well I have a theory.
First of all, let's look at the way that dragons are controlled in Harry Potter. We can start in the most obvious place, the first challenge in Harry Potter and the Goblet of Fire. Consider this letter to Harry from Sirius Black.
“Dear Harry, Congratulations on getting past the Horntail. Whoever put your name in that goblet shouldn't be feeling too happy right now! I was going to suggest a Conjunctivitus Curse, as a dragon's eyes are its weakest point - 'That's what Krum did!' Hermione whispered - 'but your way was better, I'm impressed.'"
(Harry Potter and the Goblet of Fire, chapter 23)
The most common response to a dragon, even when you want to steal its eggs, is apparently to use a conjunctivitus curse. Sirius suggested it and Krum attempted it.
And then how about this passage from Deathly Hallows?
“A gigantic dragon was tethered to the ground in front of them, barring access to four or five of the deepest vaults in the place. The beast's scales had turned pale and flaky during its long incarceration under the ground, its eyes were milkily pink; both rear legs bore heavy cuffs from which chains led to enormous pegs driven deep into the rocky floor. Its great spiked wings, folded close to its body, would have filled the chamber if it spread them, and when it turned its ugly head toward them, it roared with a noise that made the rock tremble, opened its mouth, and spat a jet of fire that sent them running back up the passageway.
'It is partially blind," panted Griphook, "but even more savage for that. However, we have the means to control it. It has learned what to expect when the Clankers come. Give them to me.'”
(Harry Potter and the Deathly Hallows - Chapter 26.)Again, the poor dragon is being controlled by blinding it. Spare a thought for the poor dragon.
Now if you've been paying attention to previous blogs then you'll know that dragons eyes have hypnotic properties and that there's a prevailing view that they use the same hypnotic powers in order to communicate. In other words, they use eye contact to communicate.
So what if every time a wizard blinds a dragon, he or she is taking away the means that dragon has to communicate? What if every conjunctivitis curse takes away a little bit more of each dragon’s ability to share its knowledge and intelligence with the world? What if the practice of blinding dragons is now so commonplace that the secret of the dragons’ intelligence is all but forgotten in the wizarding world?
I think we've stumbled onto a great injustice in the wizarding world.
