The Garden of Earthly Delights, Hieronymus Bosch
Right at the close of the Medieval era, we have Hieronymus Bosch. His work has returned to popularity in recent years because of just how psychedelically twisted and odd it is. His sense of perspective broke some conventions of the time, too. Much of his work was done as triptychs--a painted kind of wooden cabinet, with different, related scenes on the interior and exterior panels. This image is the center panel of The Garden of Earthly Delights. It's like a brilliant, demented Where's Waldo.
