The following pages present evidence in the discussion concerning the original colours of the so-called "yellow" coffins of the 21a Theban Dynasty (1070-945 BCE). The examples shown are taken from original CESRAS photos of coffins, mummy-boards and uschebti (shabti) boxes found in the Royal Cache, TT320, in 1881 and in the "2nd Cache", Bab el-Gasus, in 1891.
In the earlier scholarly egyptological literature it is often stated that the decoration of these objects was outlined and painted on a yellow background, or that the background was painted yellow. As the coffins appear to be yellow and are thus correctly called "yellow coffins", we believe that the evidence shown here will convince that this was not the case, at least with the considerable material which we have studied.
Less frequently is maintained that the background was the raw white gesso (lime plaster), the final step in smoothing the surface (see construction methods on this site) and that the decoration was applied to this white surface. The finished painted decoration was then coated with a protective varnish. The physical evidence presented here clearly supports this view.
A second, perhaps more important, point of discussion is that of the nature of the varnish used; was it a transparent yellow, or clear and colourless ? We shall demonstrate that there would have been no logic in applying a yellow coating. The mutation of stable, painted colours makes it clear that the varnish was clear when applied and yellowed with age.
