Photomicrograph of the partially cleaned area H located on Domitian’s muscle cuirass. The brownish varnish has been partially removed so it is still present in parts of the image. Pigments visible in the image are: Orange/yellow, blue, red, green and white. We have not been able to identify the green pigment in this area.
