Drawing on ancient solar mythologies that revered the sun as a divine source of life, Petroc Sesti channels two decades of optical experimentation into a sculptural exploration of geometry, light and colour. His works translate the invisible dynamics of light waves into vivid chromatic form, sustaining humanity’s enduring fascination with celestial energy.

Expanding the scale and ambition of optical sculpture, Sesti realizes the largest and most ambitious prism to date. Rooted in Newton’s inquiry into the secret architecture of the rainbow, yet wholly contemporary, these works bridge ancient cosmology and modern scientific insight.

Standing as refractive beacons, the tetrahedral prisms capture and disperse sunlight into shifting spectral fields that move with the viewer, transforming perception into an active encounter with the immediacy of light.
