215.—Uas.
216.—Dad.
Four of the hieroglyphs most usually worked into ornamental designs are the ankh, a girdle, or symbol of life; the thet, another form of girdle, with longer bow-tie in front, which, as always identified with Isis, may have been a primitive feminine girdle, the ankh being masculine; the uas, a stick of authority, or symbol of power; and the dad, a row of columns, or symbol of stability.
As early as the Old Kingdom we find wooden framings, or lattices, ornamented with dad signs; and this continued at least as late as Amenhotep II. The dad also appears in what is probably copied from pierced woodwork, in a relief at Qurneh of Ramessu I.
