ARMILLARY W/ BALL 4″ WHITE – 54638

Armillary spheres are essentially celestial navigation tools used for mapping stars and planets. Shaped like rings, they feature circles of metal bands that represent the orbits of different celestial bodies, pivoting on a vertical axis representing Earth’s poles. Some armillaries were used for astrological purposes, while others served purely educational purposes, helping astronomers understand the complex movements of the solar system.
