ation: FIG. 11.--Assyrian glazed and enamelled pottery.]

Characteristic of the Parthian period is a coarse green glazed pottery
of which the slipper-shaped coffins, of the time were made (British
Museum, Nos. 1645-1647) (21). This glaze possibly contains a small
amount of lead; in appearance it is not unlike the contemporary
translucent blue glaze of Egypt. The Egyptian glaze certainly spread
into western Asia, and we find the last specimens of it in the tiles
from the destroyed city of Rhagae in Persia, which may be as late as the
13th century A.D. The lead glazes, unknown in Egypt till the late Roman
period, may be of Asiatic origin, though this important point is by no
means clear.

GREEK. _Study of Greek Vases_.--It is not so many years since an account
of Greek pottery would naturally have followed chronologically the
history of Egyptian pottery with little overlapping; but recent
discoveries have reversed all such ideas, and, while up to the end of
the 19th century the earliest remains to be traced on Greek soil could
be assigned at the furthest to the period 2500-2000 B.C., it is now
possible not only to show that at that period technical processes were
