These departures from decorative usage are, however, exceptional, and the dual symmetry is always observed where space permits.
[Illustration: Fig.

106 .-- Frieze of uraei and cartouches.] In Pharaonic times, the tableaux were not over-crowded.

The wall-surface intended to be covered was marked off below by a line carried just above the ground level decoration, and was bounded above by the usual cornice, or by a frieze.

This frieze might be composed of uraei, or of bunches of lotus; or of royal cartouches (fig.

106) supported on either side by divine symbols; or of emblems borrowed from the local cult (by heads of Hathor, for instance, in a temple dedicated to Hathor); or of a horizontal line of dedicatory inscription engraved in large and deeply-cut hieroglyphs.
