Geometric patterns wind their way among biblical and classical scenes.

The personified Four Virtues are featured, as are the biblical stories of King David and David and Goliath.

Most of the artists who designed the floor were local to the city.

First, they created a sketch.

They chiseled their ideas into white marble whose depressions were then filled with dark stucco.
