THE FRIEZE ON THE SOUTH SIDE.

We now return to the S.W. corner, and consider the other part of
the procession, which moves along the S. side towards the same
central point of meeting on the E. facade. Here, too, we find a
marshal, who is preceded by horsemen similar to those in the N.
frieze, but not producing so strong an impression of thronging,
bustling, yet restrained and disciplined, life and force. The cavalry
is preceded by a train of chariots, as on the opposite side, the first
and last of which are standing still, while the drivers receive their
instructions from the marshals. In front of these are men on foot,
then cows, most of which walk along quietly enough, but some make
desperate attempts to escape their fate.1

British Museum.
