*The creation of a mosaic was a complicated procedure that called for careful timing and teamwork... Walls were painted with resin or tar before being covered with the first of three layers of plaster A

colored glass, marble, and semiprecious stones were pressed into the wet plaster so that they
projected at a slight angle. The stones thereby better reflected light and imbued the finished mosaic
with a shimmering life of its own."
