In the long-ago days such things were not known. Thousands of years ago, far away in Assyria, the Assyrian people learned to make pictures and to carve them out in stone. In Egypt, too, the Egyptians traced pictures upon the walls of their temples and upon the painted mummy-cases of the dead. Then the Greeks made still more beautiful statues and pictures in marble, and called them gods and goddesses, for all this was at a time when the true God was forgotten.
