You may not have heard of the monumental horror-image before, but like the Supreme Court and pornography, you know it when you see it. The little girls in The Shining, the statue of the demon in The Exorcist, the titular entities in The Wicker Man and It Follows: Though they’re rarely discussed compared to jump scares, gore, monsters, slashers, torture, or other hallmarks of the genre, the monumental horror-image is everywhere. Chances are good that if a movie has ever really frightened you, you have strange, standalone sights like these to thank.

The things you see in images like these aren’t brandishing a chainsaw or baring a mouthful of fangs, but something about them feels completely terrifying anyway. It’s not just scary, it’s wrong, like you’re seeing something that should not be.

Why “monumental?” In part, because subjects of these images are horrifying more for what they represent than what they actually do. In most cases, they don’t do anything but stand there. Yet seeing them alone is enough to indicate that something dreadful going on. Just as monuments in real life commemorate events or embody ideals, these images function as horror’s forward-facing surface — “monuments” to the deeper evil they connote.

Inspired by a twitter thread I did on the topic that went viral recently, I wrote about the monumental horror-image for The Outline, and they made an incredible visual presentation out of it that you really should check out if this subject interests you at all. This piece was nearly 20 years in the making and i’m so proud of how it turned out.
