The scarabs of the time of Khufu are all small and of fine work but without elaboration, and the colors are delicate, beautiful and permanent. Under Khaf-Ra or Khefren, there was a deterioration; the work is inferior and the glazing has often perished, indeed good glazes are rare after this period until the XIth Dynasty; (_circa_ 2500 B.C.) The glazes of this latter period are hard, unalterable and of fine colors, some under the XIIth are fine but often they are decomposed. Blue is a special color of this time and it is also used in the sculpture. Under Pepi, IVth Dynasty, (_circa_ 3233 B.C.,) the scroll pattern first arises as a system, but is not found continuously in the scarabs of his period. In the XIIth Dynasty, (2466-2266 B.C.,) the continuous scroll pattern was developed, it became general in the XIIIth, (_circa_ 2233 B.C.,)and XIVth Dynasties, and lingered as far as the XIXth (1400 B.C.) Brown scarabs were originally green glazed but have faded, white were originally blue, excepting possibly some of Amen-hotep IIIrd. There are also white and gray, without any glaze remaining, which were originally blue or green. The cowroids, with a rope border on the back, are of the Hyksos period. The XVIIIth Dynasty (1700-1400 B.C.,) begins with some of a poor style but it soon disappeared. The peculiarity of the first part of this Dynasty is the dark green glaze--rather greyish--this was followed by those of brilliant tints in the time of Amen-hotep IIIrd, (1500-1433 B.C.,) those of red, yellow, violet, chocolate and other colors. They are never met with later. At the end of the XVIIIth Dynasty, pottery rings came into general use and are more frequently met with than scarabs. Their range is from Amen-hotep IIIrd to Rameses IInd. In the XVIIIth Dynasty the art of glazing deteriorated, and most of the scarabs of this period have now lost their original colors, and are at present only browns and greys. Under Rameses IInd and his successors the work is poorly done. In the XXIVth (the Saïtic Period, _circa_ 733 B.C.,) and in the XXVth Dynasties, there was a revival and better work and glaze and there remain of this time some fine examples. The XXVIth (666-528 B.C. Saïtic,) was poor in results but the work neat. The scarab form had nearly run its course and continued, in a debased style, until the close of the native monarchy with the XXXth Dynasty (_circa_ 378 B.C.)
