With the knowledge we now possess of the Mycenaean civilisation, obtained not least through examination of the Mycenaean tombs and their rich contents, it seems to me that the present is the time to take note not only of those objects found in the tombs, but also of those which are missing and which one would expect to find. Because of the apparent absence of lamps, I was able to point out that an earthenware object which was earlier taken for a drinking vessel or a scoop was probably a clay lamp. In the relatively dark tomb chambers artificial light was undoubtedly needed, especially in secondary burials, when the whole wall blocking the doorway was not removed, but a small opening, made in the upper part of the filling, sufficed for the introduction of the corpse into the tomb. Careful examination of the dromos and the wall blocking the doorway have proved that in many cases such a procedure took place. In the larger and richer tombs excellent stone lamps have been found. The occurrence of such lamps in the more pretentious tombs gave me the idea of looking for clay ones in the ordinary tomb chambers.
