the monument, we may refer to them as giving us some clue to the
process of bronze casting at that period.

Some practical hints (706-709).

If you wish to make a figure in marble, first make one of clay, and

the holes in it, and thrust them so far in at each hole that each
white rod may touch the figure in different parts of it. And colour
