|The Garden of Earthly Delights by Hieronymus Bosch. Painted about 1490 to 1510|
Triptychs are generally 'read' from left to right. The left-hand panel depicts God introducing Adam to Eve. The square central panel shows the Earthly delights being enjoyed, frequently through the medium of alarming insertions! (see Detail 1, below.) The right-hand panel is clearly meant to represent Hell. It's easy to see the message as a warning against moral sin during one's lifetime and the punishment to come for misdeeds to be meted out in the afterlife. As the majority of the population could not read, graphic illustration was often the way of telling a story as with the telling of Bible stories via the stained-glass windows of a church.
