Its opening within the capital and above was a cubit.
Its opening was round like the work of a pedestal, a cubit and a half; and also on its opening were engravings, and their panels were square, not round.
The four wheels were underneath the panels; and the axles of the wheels were in the base.
The height of a wheel was a cubit and half a cubit.
The work of the wheels was like the work of a chariot wheel.
Their axles, their rims, their spokes, and their hubs were all of cast metal.
