An allegorical stained glass design by Eugène Grasset, depicting a female figure representing spring amidst flowering irises and a blossoming tree.

Eugène Grasset, a Swiss designer active in France, produced this work during the height of the Art Nouveau movement. The composition depicts a female figure personifying the season of spring. She wears a floral crown and carries a basket of blossoms, while reaching towards a cluster of irises. The background features a flowering tree and birds in flight, framed by a decorative border of repeating wave and sun motifs. Grasset was a significant figure in the development of modern graphic design and decorative arts. His approach combined a study of natural forms with the stylised geometry characteristic of the period. The use of leaded lines in this stained glass piece defines the contours of the figure and the surrounding flora, creating a clear separation between the foreground and the sky. The colour palette relies on soft blues, earthy browns, and muted yellows, which reflect the transition from winter to the warmer months. This piece demonstrates the influence of Japanese woodblock prints on European artists of the late nineteenth century, particularly in the flat treatment of the sky and the rhythmic arrangement of the border. The figure is rendered with a sense of grace, typical of Grasset's illustrations for posters and books. The work functions as a decorative panel, intended to bring the natural world into an interior space through the medium of light and glass. By focusing on the seasonal cycle, Grasset connects the viewer to the rhythms of nature, a common theme in his broader body of work. The balance between the organic shapes of the flowers and the structured grid of the lead cames provides a sense of order to the scene, ensuring the composition remains coherent when viewed as a whole.
