This massive glass cube holds a secret: The Mystery Cosmographicum of the great astronomer Johannes Kepler .
When the unknown young mathematics teacher published this world model in 1596, it turned him from one day to the next to one of the most famous astronomers in Europe, because he could explain with the help of the five Platonic bodies, the distances of the planetary orbits in the Copernican planet system as well and precisely as anyone in front of him. The engraving from his book is one of the icons of astronomy history .
The drawing of the nested Platonic solids and the intervening planetary orbits inside the cube consists of hundreds of thousands of microscopic dots fused into the glass from outside with a strong precision laser. The lines, which are only 0.3 millimeters thin and stand out particularly clearly under lateral illumination, precisely reproduce the model down to its small interior structures.
This historical and astronomical rarity was made in small numbers. The unusually large glass cube is an impressive eye-catcher and a valuable, noble gift for every friend of astronomy.
