Art may be revered for its beauty, but there’s a lot of ugliness there too, even in the work of its most famous practitioners. Not to mention blood, guts and existential horror, of course. Come to think of it, this is just the time of year for such things, so if you’re in the holiday spirit and also enjoy yourself some fine art by some of the world’s most famous artists, you’re in luck: here you’ll find a (blood) spattering of highbrow horrors to inform your Halloween revelry. And you won’t find any little namby-pamby scary paintings like Edvard Munch’s The Scream — we’re talking keep-you-up-at night frights. Or, at least, these are the ones that keep me up at night. Feel free to add the artwork you’d most like to hide in the freezer for all time in the comments.
