The Triangle: From Mexican Pyramids to Colorful and Imaginary Landscapes

The artistic work of Dr. Kuno Stöckli was initially characterized by the triangle. Even as a child, he encountered this geometric shape every day right on his doorstep.

In Mexico, the triangle came alive for him. On several journeys between 1976 and 1979, the pyramids of earlier cultures were a true inspiration. Left-sloped and right-sloped lines that intersect dominate his paintings in this phase.

The Octagon: From Castel del Monte in Puglia to geometric figures

A key event in the life of Dr. Kuno Stöckli was an art-historical excursion to Italy in 1970.
He visited the Castel del Monte in Puglia. Its floor plan is a regular octagon. At each corner there is again an octagonal tower. Stöckli discovered that the floor plan is based on a circular game.

Typical for his abstraction are clearly recognizable geometric lines and the division of the image content into individual surfaces.

The World of Crystals: From Brazilian Gemstones to Crystal Shapes

In Brazil, the world of crystals opened up for Dr. Kuno Stöckli. Now the artist encountered his geometric forms again and a world of colors opened up in front of him.

Nature and art are connected by symmetry. In art, it is used as a graphic structuring element. But where is symmetry found in nature? In crystals, the surfaces are in symmetrical relationships to each other. 

Depending on the crystal system, after a reflection or rotation around one axis, one surface is reproduced exactly on the other.

Similar to nature, symmetry in art can arise through vertical or horizontal axes or at individual points.

Art and Nature: From Ruby to Lapis Lazuli

Despite his retirement in 1999, Dr. Kuno Stöckli continued to search for new ideas for artistic implementations. His love for nature and the natural beauties in the mineral kingdom brought him a new inspiration. Initially, he specifically integrated stone discs into watercolor paintings, which he selected according to color and structure. This resulted in a dialogue between painting and stone.

Geology and beryl as inspiration

Nature itself was Kuno Stöckli's most important inspiration for his artistic works. The contrast and tension between exact/ordered and random/chaotic inspired him. Volcanism with its imposing geological structures played a major role. To study these phenomena, he undertook many journeys. 

His passion for beryls began in Brazil. He collected every variety such as aquamarine, emerald or heliodor. Through this decades-long occupation with gemstones, he succeeded in building up a considerable collection of beryl.


Offers for families

Design your own mandala! A station is integrated into the special exhibition where you can try out for yourself how to design beautiful figures with a compass, ruler and pencil.

During the Saxon holidays, the special exhibition is also part of the respective holiday programme:

Easter holidays 15-24 April 2022
Ascension Day/Pentecost, 26-29 May/4-6 June 2022

The elements: Each mineral consists of one, two, three or even more elements. Like building blocks, they assemble a mineral. This creates amazing patterns that you can discover in the artworks.

Summer holidays, 16 July - 28 August 2022, Thu-Sun

The drop and the stone: Experience many adventures with the little drop Of Blubb! He also tells you how the aquamarine got its name.

Autumn holidays, 15-31 October 2022

It's bubbling in the volcano: Do you want to know where and how volcanoes erupt? Dark ash clouds and sparkling lava also look impressive in paintings.
