A finger planetarium from the 16th century

The astronomers' ring is a particularly distinguished and beautiful example of a portable armillary sphere, the model for which dates from the 16th century. At first glance it looks like an ordinary finger ring. In fact, however, it consists of five individual rings that are artfully connected by axles and can be twisted against each other. This allows the ring to be unfolded, creating a mini planetarium. The astronomers' ring is made of a galvanically gold-plated zinc-copper alloy.

The reconstructed inscription is based on the still largely astrologically oriented astronomy of the 16th century.

On the two outer rings is written:
Ptolomaius invenit = has invented.
Copernicus invertit = has reversed it
Joh. Kepler calculavit = calculated it
AstroMedia fecit MMXXI = did it in 2021

On the inner rings are the symbols of the following signs of the zodiac:
Aries, Taurus, Gemini
Cancer, Leo, Virgo
Libra, Scorpio, Sagittarius
Capricorn, Aquarius, Pisces
