This solid glass cube holds a secret: the Mysterium Cosmographicum of the great astronomer Johannes Kepler.
When the unknown young mathematics teacher published this model of the world in 1596, it made him one of the most famous astronomers in Europe overnight, because with the help of the five Platonic solids, he was able to explain the distances between the planetary orbits in the Copernican planetary system as well and as precisely as no one before him. The copperplate engraving from his book is one of the icons of astronomical history.
The drawing of the interlocking Platonic solids and the planetary orbits between them inside the cube consists of hundreds of thousands of microscopic dots that were melted into the glass from the outside using a powerful precision laser. The lines, which are only 0.3 millimetres thick and stand out particularly clearly when viewed from the side, reproduce the model down to its smallest internal structures.
This historical and astronomical rarity was produced in a small edition. The unusually large glass cube is an impressive eye-catcher and a valuable, elegant gift for any friend of astronomy.
