Expansion n°1, exhibited at the Donjon de Vez, is part of César’s “Expansions” series, created in 1967. Using polyurethane, a material with unique properties, this sculpture monumentalizes organic forms that appear both frozen and in motion.
Expansion no. 1: Caesar’s living sculpture
Between softness and roughness
In Expansion n°1, the work’s massive, round form contrasts with the rough, rusty texture of its surface. This paradoxical piece combines the apparent softness of its form with the hardness of the material, a tension characteristic of César’s sculptures. Here, the artist explores the infinite possibilities of polyurethane, whose casting, layering and finishing give the work a quality that is both fixed and alive.
A monumental, living work of art
Expansion n°1 evolves over time, with rust and transformations adding a living dimension to the work. This sculpture is not simply a form, but a sensory and temporal experience, marked by the random creative process and interaction with its environment.
