Am Steinhof Church, mosaic design for the main altar 1905

Koloman Moser's 1905 design for the main altar of the Am Steinhof Church is a striking example of Art Nouveau. The composition features a central figure of Christ surrounded by angels and saints, all rendered in a stylized, flowing style characteristic of the movement. The design utilizes a blend of geometric shapes, intricate patterns, and natural motifs, such as the stylized waves at the bottom of the composition. The use of gold and white tones creates a sense of spirituality and grandeur.
