If you want to see something bizarre, but well executed, take a look at the signature work from Hieronymus Bosch; “The Garden of Earthly Delights.” The activities he depicts or alludes to could make Caligula blush (with jealousy).
I believe Bosch died after being recommitted to a mental asylum by his family.
That Bosch triptych has been the object of prurient and morbid fascination for a very long time. It’s been very influential and still is. Dali, for instance.
