The cycle of the last endings in Notre-Dame of Benva presents the particularity of introducing a third level, intermediary between damnation and salvation : the Purgatory.

The belief has imposed itself gradually, in the late Middle Ages, and the image shows it.

Penitent souls are crammed together in a jail, behind grills.
They undergo the torture of the fire.

However, unlike Hell where torture shall never end, the souls of the Purgatory can receive help from angels giving them water, to drink and freshen themselves up, and their imprisonment is only temporary.

The jail has no roof, some are already leaving it to become elect.
