[Illustration: Fig.

236 .-- Tile from step pyramid of Sakkarah.] Up to the beginning of the present century, one of the chambers in the step pyramid at Sakkarah yet retained its mural decoration of glazed ware (fig.
235).

For three-fourths of the wall-surface it was covered with green tiles, oblong in shape, flat at the back, and slightly convex on the face (fig.

236).

A square tenon, pierced through with a hole large enough to receive a wooden rod, served to fix them together in horizontal pyramid of rows.[67] The three rows which frame in the doorway are inscribed with the titles of an unclassed Pharaoh belonging to one of the first Memphite dynasties.
