3Hieronymus Bosch, The Garden of Earthly Delights, 1503–1515
This fantastical triptych is generally considered a distant forerunner to Surrealism.
In truth, it’s the expression of a late medieval artist who believed that God and the Devil, Heaven and Hell were real. Of the three scenes depicted, the left panel shows Christ presenting Eve to Adam, while the right one features the depredations of Hell; less clear is whether the center panel depicts Heaven. In Bosch’s perfervid vision of Hell, an enormous set of ears wielding a phallic knife attacks the damned, while a bird-beaked bug king with a chamber pot for a crown sits on its throne, devouring the doomed before promptly defecating them out again.
Originally built for various reasons, from defensive fortifications to storage and religious sanctuaries, many of these underground cities have endured over centuries, preserving fascinating glimpses into past lives and cultures.
