The remaining stages probably followed the same rule of diminution--the fifth being a square of 104, the sixth one of 24, and the seventh one of 20 feet.

Each of these stages had a height of fifteen feet.

Upon the seventh or final stage was erected the shrine or tabernacle, which was probably also fifteen feet high, and about the same length and breadth.

Thus the entire height of the building, allowing three feet for the crude brick platform, was 150 feet.
The ornamentation of the edifice was chiefly by means of color.

The seven stages represented the Seven Spheres, in which moved (according to ancient Chaldaean astronomy) the seven planets.
