Devil on Night-chair

It is presumed that Bosch had knowledge of the Visio Tungdali, a twelfth century handwriting that describes a vision of a journey through hell. This was possibly the basis for this devil, crowned with a cauldron, symbolising the diabolical inferno fire. He is sat on a night-chair, which offers him the possibility of excreting the gorged souls.

Hiëronymus Bosch shows us how we mortal souls, arisen from earthly paradise, are on our way to the atrocious ordeals of hell via our unchaste lives on earth.
