In Basel, the artwork "Tageszeiten" by Hans Weidmann is a captivating piece of glass art located at the Universität Institut für Anorganische Chemie on Spitalstrasse 51. Created in 1962, this three-part installation was commissioned by the Baudepartement Basel-Stadt for the former institute. The artwork is integrated into a large, grid-patterned window made of antique glass in the stairwell's facade. Weidmann's "Tageszeiten" features three distinct birds: an owl, a griffin, and a swift, each representing different times of the day. As the natural light changes throughout the day, the scenes and the depicted times of day transform, offering a dynamic visual experience. This integration of art and architecture not only enhances the building's aesthetic but also engages viewers with its evolving imagery.
