Prussian blue 

Kazuo Shiraga made this artwork with paint, and it’s dominated by dynamic, sweeping brushstrokes in Prussian blue. Here, the curve is the dominant motif. We see the curve, which can be traced back to ancient symbols, such as the Ouroboros, the snake eating its tail, a symbol of cyclicality and eternal return. Here, the blue curve surges, crashes, and dissipates, echoing the dynamism of the Great Wave familiar to us from Hokusai's print. These curves, whether in the form of a serpent or a wave, evoke deep, primeval forces. Consider how these images engage us on a visceral level. They stir subconscious recognition of life's ceaseless flow, its rises and falls, its moments of explosive energy and quiet resolution. The curve continues its journey through time, resurfacing in various forms, each imbued with new meanings. It is a powerful, ever-evolving symbol deeply embedded in our collective consciousness.
