impurities, they pour upon his head the waters of youth and life. The
position and functions of these co-operating gods were strictly defined in
the theology. The sun, travelling from east to west, divided the universe
into two worlds, the world of the north and the world of the south. The
temple, like the universe, was double, and an imaginary line passing
through the axis of the sanctuary divided it into two temples--the temple
of the south on the right hand, and the temple of the north on the left.
The gods and their various manifestations were divided between these two
temples, according as they belonged to the northern or southern hemisphere.
This fiction of duality was carried yet further. Each chamber was divided,
in imitation of the temple, into two halves, the right half belonging to
the south, and the left half to the north. The royal homage, to be
complete, must be rendered in the temples of the south and of the north,
and to the gods of the south and of the north, and with the products of the
south and of the north. Each sculptured tableau must, therefore, be
repeated at least twice in each temple--on a right wall and on a left wall.
Amen, on the right, receives the corn, the wine, the liquids of the south;
while on the left he receives the corn, the wine, and the liquids of the
north. As with Amen, so with Maut, Khonsû, Mentû, and many other gods. Want
of space frequently frustrated the due execution of this scheme, and we
often meet with a tableau in which the products of north and south together
are placed before an Amen who represents both Amen of the south and Amen of
the north. These departures from decorative usage are, however,
exceptional, and the dual symmetry is always observed where space permits.

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
