At Medinet Habu and Karnak--on the higher parts of these temples, where the work is in granite or sandstone, and exposed to full daylight--the bas-relief decoration projects full 6-3/8 inches above the surface.

Had it been lower, the tableaux would have been, as it were, absorbed by the flood of light poured upon them, and to the eye of the spectator would have presented only a confused network of lines.

The models designed for the study of the round are even more instructive than the rest.

Some which have come down to us are plaster casts of familiar subjects.

The head, the arms, the legs, the trunk, each part of the body, in short, was separately cast.
