This west wing room was a ceremonial room with a marble floor and shale. The pavement fell victim to the material collectors and has disappeared so that only the footprints of the slabs remain visible. A large amount of painted plaster from the walls and vault has been taken. The best preserved decoration is that of the north-east wall, in particular of the upper zone. On a green background stands out a composition of a yellow, red or black architecture. A compartment is decorated with a loutrophore. In the center of the composition, a perfume burner adorned with two phoenixes is suspended by a chain. From the decor of the vault we can imagine an idyllic and sacred landscape. In the center of a diamond-shaped caisson stands a small temple adorned with deer antlers. There is also a tower and a building with a portico. From the reconstitution of the wall we can deduct the height of the room which was 4.42 meters (14.5 ft).
