Hieronymus Bosch (Jeroen van Aken, ca 1450-1516), The Garden of Earthly Delights, triptych (ca 1500), right wing, detail.

Prado Museum, Madrid

The middle of the right wing is occupied by the so-called Tree Man. His egg-shaped torso is borne by a pair of rotting tree trunks, which rest on a pair of boats. His hindquarters have rotted away, revealing a hellish tavern scene within, while his head supports a large disc on which devils and their victims promenade around a large bagpipe. His face looks over the shoulder to regard the disintegration of his own body. To the right, a pack of hounds bring down a knight, still holding in one mailed fist a chalice as a proof of having committed acts of sacrilege, comparable with the scene of the helmeted nude figure astride a cow, holding a chalice, in the right wing of the Haywain. Above the Tree Man, a pair of huge ears advances like an infernal army tank, immolating its victims by means of a great knife.
