Alfons Mucha designed the stained-glass window in St. Vitus Cathedral depicting Saint Wenceslas.
Mucha was a Czech artist best known internationally for his Art Nouveau posters, but he also produced major religious and national artworks. His window in Prague’s cathedral was created in the early twentieth century and installed during the cathedral’s long completion campaign.
The composition presents Saint Wenceslas, the patron saint of Bohemia, together with members of the Přemyslid dynasty. Its flowing outlines, decorative plant forms, flattened perspective, and jewel-like colors show Mucha adapting Art Nouveau to a sacred historical subject.
St. Vitus Cathedral contains stained glass by several artists, so the building should not be attributed entirely to Mucha. Other windows belong to different periods and makers, including modern Czech artists. Mucha’s contribution is especially recognizable because its ornamental style differs from the cathedral’s older medieval fabric.
