I recently read Terry Pratchett's The World of Poo, which included a short segment about a wyvern, including an illustration. no, that's not it I've run into wyverns in my reading in the past, but it got me thinking: Wyverns are similar to dragons, but we don't see them often. They don't seem to be as well known a beast as a dragon. Until more recent times, wyverns were nearly interchangeable with their dragon cousins, in British heraldry, for example, but seem to have fallen out of favor. Perhaps as literacy has taken over for iconography, and heraldic symbolism has become less important, folks simply forgot about wyverns. But we haven't forgotten dragons. What is it about dragons that captures our imagination, more than wyverns?
Wyverns appear, to this observer, to be a much more likely anatomical form that their four-legged dragon counterparts. Wyverns have two legs and two wings, like a bird. Seems odd right? Dragons--western dragons anyway--have four legs, and two wings. Which seems to make more sense.
|A wyvern is built like this bird: two legs, and two wings|
But when you compare these beasts to others in the animal world, its actually the dragon that's odd. Most animals have four limbs. A wyvern has four limbs too, but a dragon has six limbs: four legs and two wings. What else has that? Nothing, that's what.
|A dragon is built like nothing else: four legs, and two wings|
Is there really nothing else built like a dragon? An insect perhaps? They have six legs, right? But flying insects have six legs and two or four wings, for total of eight or ten limbs!* And antennae, and exoskeletons, so... probably not a good archetype.
Know what else does have four limbs plus two wings? Flying horses, griffins... and angels. Maybe it's because this anatomical form is so alien to us, is why we've chosen it for our most popular mythical creatures.
We need crazy, just as much as crazy needs us. Wyverns just aren't as crazy as they need to be.
