Depict a scene inspired by Matthew 28:19-20, featuring a visual interpretation of the commissioning of the disciples. The scene should radiate elegance, organic forms, and intricate detail, reflecting the key aesthetics found in the Art Nouveau period. Remember, the art ought to honor Christianity in a respectful and devotional manner without the use of any text or words. Key elements might include diverse disciples gathered together, or references to spreading the faith across the globe. Ensure the final image honors the broad color palette and intricate elegance of the late 19th-century Art Nouveau style.
