I attach pictures of the 8 allegories that decorate the four corners of the chapel. Unfortunately, light was not enough, so some of the images are blurred.
The allegories represent the seven virtues and, to fill the free eight place, Unjustice was put next to Justice.
The images feature the polygonal halos that can be seen in the so called Charles VI Tarot.
