His work can also be categorized based on six major motifs: the horse and rider, apocalypse, landscape, music, geometry, and scientific imagery. The horse and rider motif demonstrated his ongoing battle against traditional representational and materialistc values. Similarly, his apocalyptic works portrayed a dichotomy between disaster and paradise, often alluding to the Bible. His landscape pieces, although loosely based in nature, depicted a transition to a more geometric style while still alluding to destructive themes. His focus on music, perhaps the most profound influence on his art, displayed his interest in the simultaneous experience of more than one sense. Kandinsky's fascination with geometry underscored his new aesthetic innovations of manipulating perception of time and space. Finally, his works with scientific imagery convey a sense of spiritual regeneration, with his portrayals of life in its most primordial form.
