The Garden of Earthly Delights is the modern title given to a triptych oil painting on oak panel painted by the Early Netherlandish master Hieronymus Bosch, between 1490 and 1510, when Bosch was between 40 and 60 years old. It has been housed in the Museo del Prado in Madrid, Spain since 1939.

The right panel (220 × 97.5 cm, 87 × 38.4 in) illustrates Hell, the setting of a number of Bosch paintings. Bosch depicts a world in which humans have succumbed to temptations that lead to evil and reap eternal damnation. The tone of this final panel strikes a harsh contrast to those preceding it. The scene is set at night, and the natural beauty that adorned the earlier panels is noticeably absent. Compared to the warmth of the center panel, the right wing possesses a chilling quality—rendered through cold colourisation and frozen waterways—and presents a tableau that has shifted from the paradise of the center image to a spectacle of cruel torture and retribution.

In a single, densely detailed scene, the viewer is made witness to cities on fire in the background; war, torture chambers, infernal taverns, and demons in the midground; and mutated animals feeding on human flesh in the foreground. The nakedness of the human figures has lost all its eroticism, and many now attempt to cover their genitalia and breasts with their hands, ashamed by their nakedness.

Large explosions in the background throw light through the city gates and spill into the water in the midground; according to writer Walter S. Gibson, "their fiery reflection turning the water below into blood". The light illuminates a road filled with fleeing figures, while hordes of tormentors prepare to burn a neighbouring village. A short distance away, a rabbit carries an impaled and bleeding corpse, while a group of victims above are thrown into a burning lantern. The foreground is populated by a variety of distressed or tortured figures. Some are shown vomiting or excreting, others are crucified by harp and lute, in an allegory of music, thus sharpening the contrast between pleasure and torture. A choir sings from a score inscribed on a pair of buttocks, part of a group that has been described as the "Musicians' Hell".

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 grey 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. Belting wondered if the tree-man's face is a self-portrait, citing the figure's "expression of irony and the slightly sideways gaze [which would] then constitute the signature of an artist who claimed a bizarre pictorial world for his own personal imagination".

Many elements in the panel incorporate earlier iconographical conventions depicting hell. However, Bosch is innovative in that he describes hell not as a fantastical place, but as a realistic world containing many elements from day-to-day human life.
Animals are shown punishing humans, subjecting them to nightmarish torments that may symbolise the seven deadly sins, matching the torment to the sin. Sitting on an object that may be a toilet or a throne, the panel's centerpiece is a gigantic bird-headed monster feasting on human corpses, which he excretes through a cavity below him, into the transparent chamber pot on which he sits. The monster is sometimes referred to as the "Prince of Hell", a name derived from the cauldron he wears on his head, perhaps representing a debased crown. At his feet, a female has her face reflected on the buttocks of a demon. Further to the left, next to a hare-headed demon, a group of naked persons around a toppled gambling table are being massacred with swords and knives. Other brutal violence is shown by a knight torn down and eaten up by a pack of wolves to the right of the tree-man.

During the Middle Ages, sexuality and lust were seen, by some, as evidence of humanity's fall from grace. In the eyes of some viewers, this sin is depicted in the left-hand panel through Adam's, allegedly lustful, gaze towards Eve, and it has been proposed that the center panel was created as a warning to the viewer to avoid a life of sinful pleasure. According to this view, the penalty for such sins is shown in the right panel of the triptych. In the lower right-hand corner, a man is approached by a pig wearing the veil of a nun. The pig is shown trying to seduce the man to sign legal documents.

Lust is further said to be symbolised by the gigantic musical instruments and by the choral singers in the left foreground of the panel. Musical instruments often carried erotic connotations in works of art of the period, and lust was referred to in moralising sources as the "music of the flesh"."
