The photograph here not only illustrates a good example of the dark incrustation but also another feature that marred the surface of the painting while still in situ on its supporting clay wall.
Seen here are two of the many holes hacked into the painting surface to provide a key for the second phase fresco, can be seen to the right of this figure, penetrating the red panel. Interestingly, one of the holes clearly penetrates the incrustation layer indicating that this disfigurement became visable during the decorations working life.
After cleaning the painted surface was protected with the application of a 5% solution of Paraloid B72 . Each segment of the painting was then photographed, a montage constructed (figure 1).
In figure 3 the first phase lunette decoration is seen in the position it occupied in the room.
The height of the room may be thought rather speculative but the distance from the floor to the highest point of the vaulted ceiling must equal the depth of the lunette (1.5 metres), plus the height of the door (close to 2.0 metres), plus the depth of the painting between the base of the lunette and the top of the door, (at least 0.5 – 0.6 metres), adding up to a total measurement which must be about four metres.
The very fragmentary remains of the painting surviving below the lunette are illustrated in figure 4 which reveals tantalising but ambiguous details of this scheme.
The depth of the area remaining below the cupid’s feet is close to 20 centimetres and appears to show just the top edge of a decorative scheme. Interestingly, underneath this paint can be seen an extension of the lunette scheme with, on the right, the slender column flanking cupid and on the far right an extension of the red door. This would appear to be yet another example of a rethinking of the decorative scheme well into its production.
