People have never been stupid, but Europeans certainly were dim about wildlife in the Middle Ages. Take a look at these odd illustrations of animals.
Sheeps that look like fluffy dogs
A... turtle?
This oyster will be haunting your dreams
A strangely human owl
The monkeys like hairy humans
More dogs?
The amazing earless castle elephant
Another elaborate elephant
Oddly muscular dogs
Is this a lizard or what??
A fish-tailed beaver
Scary
