This celestial chart depicts a 3-dimensional view of the earth, centered on the eastern hemisphere, surrounded by a band depicting the signs of the zodiac.

The chart represents a pre-Copernican view of the relationship between the earth and the sun, in which the sun was believed to rotate around the earth in spiral revolutions. The drape-style title cartouche floats in the sky, with clouds and putti holding birds tethered to ribbons in the background.
