Mythic primitivism return to innocence: Koloman Moser Ver Sacrum, 1898

Koloman Moser excelled in diverse fields, including painting, graphic design, interior design, fashion, and scenography, embodying the "Gesamtkunstwerk" (total work of art) philosophy of the Vienna Secession. 

His graphic designs for the Secession's journal Ver Sacrum, became a model for graphic design and  helped define the art of his time. 

Something else: Moser designs have the peculiarity of "reducing" the shapes of furniture and art objects while maintaining high-quality ornamentation, a characteristic of Viennese Art Nouveau. 

He is credited as the first Austrian designer to invent a complete corporate identity, in this case, that of the Wiener Werkstätte. 

Moser's designs in architecture, furniture, jewelry, graphics, and tapestries helped characterize the work of the era, drawing upon clean lines and repetitive motifs of classical Greek and Roman art and architecture in reaction to the Baroque decadence of his surroundings. Influence on Viennese Modernism: Moser's work is considered one of the most important pioneers of Viennese Modernism and one of the most influential artists of Viennese Art Nouveau.

For all of the above, Moser is the powerhouse of the Vienna Secession.
