Both the infrared reflectogram on the right and the x-ray in the centre show the original jawline, which then had the beard painted over it. Very little of the modelling in the flesh paint is evident in the x-ray but it is possible to see where the gilding of the jewelled band extends beyond the shoulder line. Infrared reflectography reveals extensive underdrawing in the face, which is almost certainly from a tracing, and the features of the face were originally marked out further to the right.
