Book excerpt: What is presented here is a preliminary crystallization of thinking about questions, problems, and aspects that presented themselves during research into the iconography of Old Kingdom elite tombs in the so-called Leiden Mastaba Project (LMP), started in 1980 for teaching advanced students. Since the Egyptian culture has been given shape mainly in connection with the residences of the kings, the elite tombs of the Memphite area only were incorporated into the database. The original paper database consists of individual files on each tomb, giving a plan, wall scheme, a concise description of each sub-theme and its accompanying texts (if present). For details on the set-up, the original questions, the intention and some preliminary results on the partially collected material in 1985, see Van Walsem, Mastaba project. The core of this essay is a combination of and an elaboration of two former lectures by the author entitled: "Some un(der)exposed aspects in the study and interpretation of mastaba scenes" and "Religious iconography of Ancient Egypt: methodological and theoretical problems".
