This video shows a close up of the glass celestial sphere that surrounds the orrery on the Atlas clock. The illustrations are engraved and the engraving is filled in black ink. The entire clock and restoration project can be seen here: http://www.my-time-machines.net/Atlas_orrery.htm. The clock is unsigned, but the spring is dated 1786 was most likely made in Paris, France.
