17 Excellent Animal Illustrations from a 16th Century Book

Between 1551 and 1558, Swiss doctor and naturalist Conrad Gessner published his magnum opus, the five-volume, 4500-page Historiae animalium, which became the period's most widely read natural history collection. Combining the work of those who came before him, like Aristotle, Pliny, and the unknown author of Physiologus, and making use of both verbal descriptions and illustrations of animals from explorers and other naturalists, Gessner attempted to catalogue all known beasts—even ones we know today to be mythological. "He often assured his readers ... that his friends' testimony was reliable, as they had personally eyeballed even the most ferocious beasts, including lions and crocodiles," writes Michon Scott at Strange Science. "When [Gessner] doubted the accuracy of the opinions he relayed in his own writings, or the validity of the illustrations he included, he prudently said so. Of the multi-headed hydra, for instance, he observed, 'ears, tongues, noses, and faces are inconsistent with the nature of serpents.'"

Historiae animalium was a standout because of the sheer number of its illustrations, which were created using woodcuts; Gessner and the artists he worked with got some animals very close to right, while others are entirely off the mark. “A visual game of telephone is, to some degree, what the artists were dealing with in the 16th century,” Tom Baione, Director of the Department of Library Services at the American Museum of Natural History, told us when we first looked at some illustrations from Historiae animalium last year. Here are a few more illustrations for you to admire.

1. Beaver

Beavers do have pretty gnarly incisors—they're harder on the front than on the back, which is what creates the sharp edge that allows these semi-aquatic animals to chisel away at wood—but somehow, they don't look as terrifying on the actual animal.

2. Porcupine

Every species in the porcupine family—approximately two dozen of them—has a coat of quills to use as a defense mechanism. In real life, though, they don't look quite so sinister.

3. Unicorn

The first written description of a unicorn—which, unfortunately, is not real—appeared in the writings of Greek physician Ctesius, and it doesn't resemble the animal we've come to think of at all:

There are in India certain wild asses which are as large as horses, and larger. Their bodies are white, their heads dark red, and their eyes dark blue. They have a horn on the forehead which is about a foot and a half in length. The base of this horn, for some two hands'-breadth above the brow, is pure white; the upper part is sharp and of a vivid crimson; and the remainder, or middle portion, is black. Those who drink out of these horns, made into drinking vessels, are not subject, they say, to convulsions or to the holy disease [epilepsy]. Indeed, they are immune even to poisons…

This is the only way to capture them: when they take their young to pasture, you must surround them with many men and horses. They will not desert their offspring and fights with horns, teeth and heels; and they kill many horses and men. They are themselves brought down by arrows and spears. They cannot be caught alive.

In the fascinating book A Natural History of Unicorns, Chris Lavers examines all the animals that could have possibly been unicorns, and how the creature went from that first description to the beautiful, one-horned horse we think of now.

4. Fox

The drawing is a little more wolf- or coyote-like than an actual red fox, but cute in its own way.

5. Camel

This illustration seems to show a Bactrian camel. These two-humped ungulates are much rarer than their single-humped dromedary cousin—in fact, they're critically endangered. This illustration would be more accurate if the beast had more fur and higher humps.

6. Tiger

Sure, tigers are cute, but they're not this cute. While the stripes are kind of close, the happy smile, high and slender build, and fur at the end of the tail are anything but.

7. Hedgehog

Fact: No illustration could ever be as adorable as the real thing, and this drawing definitely isn't. It makes hedgehogs look shocked and a little curmudgeonly.

8. Elephant

We should all be thankful that elephants aren't this terrifying in real life. Look at that trunk!

9. Armadillo

There are 20 species of armadillo; according to National Geographic, and all of them but one live in Latin America. It's unclear which kind of armadillo this is, but it looks like it just played a wicked joke on one of its brethren.

10. Rooster

One word sums this illustration up, and that word is "Ahh!"

11. Sea Turtle

I wouldn't want to swim next to one of these guys—look at those teeth! In real life, sea turtles don't have teeth; instead, they use their beaks to eat, and stiff, gnarly-looking papillae help direct the food to the stomach.

12. Giraffe

If you'd never seen a giraffe before, and someone described it to you, you might draw its ossicones—which are actually cartilage covered in skin—as more typical horns, too. Fun fact: People once called giraffes "camel-leopards" because, thanks to the small hump on the back and the spotted coat, people thought they were a combination of camels and leopards!

13. Crocodile

This croc looks more like a red-eyed crocodile skink—at least around the eyes.

14. Ostrich

The color's not right—those feathers should be darker!—and the beak is a little too thick, but otherwise, this is a pretty good portrait of the world's largest (and heaviest!) bird.

15. Hippopotamus

Hippos are much stouter than this illustration shows, and they prefer to spend most of their time in the water, not walk on it. Hippos and crocs do sometimes face off in the wild, though it probably doesn't go quite like this illustration shows.

16. Whales

Adventures on the high seas must have been terrifying if you thought this was what awaited you.

17. Lion

Lion manes are definitely beautiful, but they're not this well groomed.

This High-Tech Material Can Change Shape Like an Octopus

Octopuses can do some pretty amazing things with their skin, like “see” light, resist the pull of their own sticky suction cups, and blend in seamlessly with their surroundings. That last part now has the U.S. Army interested, as Co.Design reports. The military branch’s research office has funded the development a new type of morphing material that works like an octopus’s dynamic skin.

The skin of an octopus is covered in small, muscular bumps called papillae that allow them to change textures in a fraction of a second. Using this mechanism, octopuses can mimic coral, rocks, and even other animals. The new government-funded research—conducted by scientists at Cornell University—produced a device that works using a similar principle.

“Technologies that use stretchable materials are increasingly important, yet we are unable to control how they stretch with much more sophistication than inflating balloons,” the scientists write in their study, recently published in the journal Science. “Nature, however, demonstrates remarkable control of stretchable surfaces.”

The membrane of the stretchy, silicone material lays flat most of the time, but when it’s inflated with air, it can morph to form almost any 3D shape. So far, the technology has been used to imitate rocks and plants.

You can see the synthetic skin transform from a two-dimensional pad to 3D models of objects in the video below:

It’s easy to see how this feature could be used in military gear. A soldier’s suit made from material like this could theoretically provide custom camouflage for any environment in an instant. Like a lot of military technology, it could also be useful in civilian life down the road. Co.Design writer Jesus Diaz brings up examples like buttons that appear on a car's dashboard only when you need them, or a mixing bowl that rises from the surface of the kitchen counter while you're cooking.

Even if we can mimic the camouflage capabilities of cephalopods, though, other impressive superpowers, like controlling thousands of powerful suction cups or squeezing through spaces the size of a cherry tomato, are still the sole domain of the octopus. For now.

According to the ASPCA, 3.3 million dogs enter shelters each year in the United States. Although that number has gone down since 2011 (from 3.9 million) there are still millions of dogs waiting in shelters for a forever home. October is Adopt a Shelter Dog Month; here are 25 benefits of adopting a shelter dog.
