Fayum mummy portraits
Starting in the 3rd century AD and finishing by about 400 we have a large body of paintings from the Catacombs of Rome, by no means all Christian, showing the later continuation of the domestic decorative tradition in a version adapted - probably not greatly adapted - for use in burial chambers, in what was probably a rather humbler social milieu than the largest houses in Pompeii. Much of Nero's palace in Rome, the Domus Aurea, survived as grottos and gives us examples which we can be sure represent the very finest quality of wall-painting in its style, and which may well have represented significant innovation in style. There are a number of other parts of painted rooms surviving from Rome and elsewhere, which somewhat help to fill in the gaps of our knowledge of wall-painting. From Roman Egypt there are a large number of what are known as Fayum mummy portraits, bust portraits on wood added to the outside of mummies by a Romanized middle class; despite their very distinct local character they are probably broadly representative of Roman style in painted portraits, which are otherwise entirely lost.
