You know not by what a frail thread we equally hang;
It is said we are images both – twitched by peoples desires;
And that I, as you, fail as a song that men time agone sang!
-Thomas Hardy, Aquae Sulis
When I first heard that gargoyles were added to medieval cathedrals to ward away evil spirits I thought, sounds legit. After all there are plenty of examples of what’s known as apotropaic magical symbols, which are intended to ward away evil. And what better way to keep away demons than to have some demons perched on your building to say, “No need to come here, guys, we got this one covered”? Then I started doing some reading about gargoyles and their history and things got a little more complicated. Why some—but hardly all—gargoyles take demonic shapes isn’t clear, and their original purpose was to serve as decorative water spouts. The word gargoyle probably derives from the Latin word gurgulio which means “throat”, although weirdly enough it also means weevil, maybe because the Romans couldn’t keep the bugs out of their bread and swallowed so many, but that’s another story. And it’s the same root word that gives us gargle and gurgle.
Anyway a lot of gargoyles are also strictly ornamental, so why did workers carve these creatures? Maybe there was some lingering pagan influence, or maybe they were created by artists who were just really into that sort of thing–the Gothic period must have been a pretty good time to be a goth–or maybe they were just expressions of the id, of our deepest fears and desires.
