Atlas Obscura is one of those websites where you could spend all day and feel like you’ve just traveled the world. Featuring less know locations, and strange spots that you might like to visit, sometimes it also has stories about monsters. Well, at least one story about monsters. A friend of mine recently shared Cara Giaimo’s story about thirteen lesser-known monsters from history. While none of these are likely to keep you up at night, they do demonstrate the endless imagination people devote to the unknown. Monsters, like religion, defy easy categorization. Is something that’s “too big” or “too small” for its type a monster? Is it a monster if it is a mix of things that don’t normally come together? Or is it merely a matter of baleful intention? What doth a monster make?

Taking a page (almost literally) from John Ashton’s Curious Creatures in Zoology, the Atlas Obscura page runs down some monsters once believed to have existed. Some of them, despite our flattened world seen only through the eyes of rationality, were actually reported to have existed. The “monster” of Ravenna, for example, was apparently a sad case of a medieval/early modern birth defect that, in the popular imagination took on monstrosity. We now know that birth defects may contain throwbacks to earlier stages of evolution, or that genetic coding may contain mutations. None of this suggests any evil intention on the part of anybody. Accidents of nature may be the saddest kind of monster of all.

A surprising number of the monsters from Ashton’s sampler here are mixes between human and animal. Indeed, that mix is still a potent force, theologically. One of the loudest voices speaking out against evolution is the one that says people are “not animals.” Having grown up with that belief, it took a couple years of college to convince me that we fit into the greater biological scheme of things. We fear that which resembles us, but is not quite us. Perhaps part of the mystique is that we haven’t quite yet learned to be humane to one another. Being a monster may just have more to do with what one does with prejudices than it does with physical features of their bodies.
