Painting (and drawing) for Messagier became the medium through which the universe spoke. Natural forms were observed and replaced by paintings within which the forces of nature could be experienced. Between 1953 and 1956 Messagier refined his pictorial vocabulary to include a kind of symmetry, closer in spirit to W. Blake than to the constructivists. Defying the laws of gravity and seemingly outside of spacetime, his paintings of this period evoke a state of suspended animation, a dream-world as conceived by Mallarmé. Allusive and dissolved forms that he painted so far gave way to vast indeterminate stretches of monochrome color, expressing Messagier's unswerving commitment to nature, air and light. Over the years his gesture became further loosened, reaching its apogee during the 1960s with wide and elegant "gyrations". These works resemble a network of loops or clouds ("nuages") wrapping and mingling together tirelessly. For Messagier, an artist had to be a social actor. In 1962, to inaugurate his new studio—located in an old mill next to "les Trois cantons" at the foot of the Charrot bridge that spans the Doubs river—Messagier organized his first massive party. Everyone from local government officials, artist friends from Paris (including Serge Poliakoff, the architect Jean-Louis Veret - a student Le Corbusier, Pierre Alechinsky), well-known gallery owners, dealers, collectors and construction workers (in brief, the entire population of village) were invited. Jean Messagier renewed that spirit as much as he could. In 1962, Jean Messagier represented France at the 31st Venice Biennale alongside Alfred Manessier, Serge Poliakoff, Andrew Marfaing and James Guitet (with Jean-Paul Riopelle representing Canada, Kumi Sugai Japan, Alberto Giacometti Switzerland, Jan Müller and Louise Nevelson the United States). The same year, Jean Messagier and Pierre Alechinsky, who first met in 1953, painted a canvas together embellished with phrases written by the art critic Charles Estienne. Between 1963 and 1965 Messagier made grass sculptures, snow drawings and won a medal for his entry in "Pour un été, La Monnaie de Paris". In the 8th São Paulo Art Biennial Messagier represented France along with four other artists. The following year Messagier created an annual shooting competition, and became a full member of the "Comité National de la Gravure Française".
