Description

Detailed image of a Ptolemaic armillary sphere, likley published in London at the end of the 18th Century.

The central terrestrial globe (labeled Terra) is surrounded by Arctic and Antarctic circles, Cancer and Capricorn tropical circles, and the equatorial circle. The entire image is set inside a zodiac band; these in turn are set within a calibrated meridian and a horizon band on Baroque acanthus and scroll base.
