The cradle (a wooden structural support) and the panel joins are prominent in the x-ray in the centre. In the upper-left corner there are brushstrokes which represent waves on water, indicating an original part of the picture has been painted out at a later date. There is also a noticeable craquelure over most of the painted surface, caused by movement in the panel. The numerous small flaked losses can be seen in the x-ray and the considerable areas of restoration appear as dark marks in the photograph taken in ultra violet light on the right.
