The Garden of Earthly Delights (detail; right panel) by Hieronymus Bosch

The Tree-Man and a pair of human ears brandishing a blade. A cavity in the torso is populated by 3 naked persons at a table, seated on an animal, and a fully clothed woman pouring drink from a barrel.

The focal point of the scene is the Tree-Man, whose cavernous torso is supported by what could be contorted arms or rotting tree trunks. His head supports a disk populated by demons and victims parading around a huge set of bagpipes—often used as a dual sexual symbol—reminiscent of human scrotum and penis. The tree-man's torso is formed from a broken eggshell, and the supporting trunk has thorn-like branches which pierce the fragile body. A gray figure in a hood bearing an arrow jammed between his buttocks climbs a ladder into the tree-man's central cavity, where nude men sit in a tavern-like setting. The tree-man gazes outwards beyond the viewer, his conspiratorial expression a mix of wistfulness and resignation.
