174 A History of Art in Ancient Egypt. " The interior of a mastaba may be divided into several ' chambers ' (there are three in the tomb of Ti), but generally there is only one. It is entered by the door in the middle of the facade. " These chambers have, as a rule, to depend upon the door for light, but there are a few instances in which they are lighted from openings in the roof. A remarkable example of the latter arrange- ment is to be seen in the tomb of Ti, where the innermost chamber, which otherwise would be in complete darkness, is lio-hted from the roof. " The chamber is sometimes quite bare, sometimes covered with sculptures and paintings such as those whose character and meaning we have already pointed out. At its further end, and always facing eastwards, stands the inscribed tablet or stele. ^i^^ t P D O D □ paoD op Mia o 1 Fig. 112.— Plan of the tomb of Ti. Figs. 113, 114.— Mastaba at Sakkarah, from Prisse. There are some chambers in which the walls are bare and the stele eno-raved, but there are none where the walls are carved and the stele plain." In the tomb of Ptah-Hotep, of which we reproduce the principal side, the stele proper is on the left, but the figures and the funerary inscriptions cover all the central part of the richly decorated wall (Fig. 115). We see, then, that the stele is the one indispensable part of this complicated whole. It was, in fact, upon the formula with which it was inscribed, that the Egyptians depended for those mao-ical ao-encies by which Osiris became the active medium of transmission between the living and the dead. " At the foot of the stele there was often a table for offerings.
