Scales Of Justice
On the northern half of the internal part of the west arch, the Scales of Justice are depicted. The whole scenery and the accompanying inscription Justice refers to and continues the eschatological concept that characterises the wall paintings of the narthex. A red semicircle, from which the scales hang by a chain, represents Heaven. An angel holds a scroll with the names of the souls to be judged while devils hold scrolls with the records of sins to be put on the balance. Also, black figures recognised as demons are trying to cheat the balance in order that the scale leans on their side.
The weighing of the soul is narrated in the book of Apocalypse 20:12, from which the Byzantine iconography draws upon the typical representation of the scene.
