 The walls of important tomb-chambers and offering chambers were heavily decorated with reliefs in stone or sometimes wood, or paintings, depicting religious scenes, portraits of the deceased, and at some periods vivid images of everyday life, depicting the afterlife.The chamber decoration usually centred on a "false door", through which only the soul of the deceased could pass, to receive the offerings left by the living.Representational art, such as portraiture of the deceased, is found extremely early on and continues into the Roman period in the encaustic Faiyum funerary portraits applied to coffins.
