The ring of the astronomers
A 16th century finger planetarium, also known as a portable armillary sphere.
At first glance an ordinary finger ring, it unfolds into a mini planetarium of 5 individual rings. 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 and Pisces.
- Measurements: Diameter inside 20 mm, outside 33 mm
Scope of delivery: multi-axis, spherical metal ring made of gold-plated zinc-copper alloy, historical information in a beautiful gift box.
