Ettore Sordini  Ettore Sordini (Milan, Kingdom of Italy, 24 August 1934 - Fossombrone, Italian Republic, 27 October 2012) was an Italian artist, a disciple of Lucio Fontana, a friend and collaborator of Piero Manzoni and a member of the Gruppo del Cenobio. He studied at the Brera Academy where his first experiences were abstract. His first major exhibition was at the Triennale di Milano in 1954. During the second half of the 1950s he came to know Lucio Fontana, Corrado Cagli and Giulio Turcato. During this period he developed a parasurreal style reminiscent of his contemporary Piero Manzoni. In 1956, together with Piero Manzoni, Giuseppe Zecca and Camillo Corvi-Mora, he published a manifesto entitled "Per la scoperta di una zona di immagini" (Looking for a zone of images) where they declared: "the picture is our idea of freedom; in its space we set out on a journey of discovery and creation of images". Between 1956 and 1957 he was involved in the publication of further manifestos:   In October 1957, Sordini took part in a group exhibition called "Arte Nuclear 1957" at Galleria San Fedele, Milan, with Piero Manzoni, Angelo Verga, Enrico Baj, Yves Klein, Franco Bemporad, Asger Jorn, Arnaldo and Giò Pomodoro, Mario Rossello and Serge Vandercam. By 1959 Sordini and Verga began to move away from Manzoni, and Sordini developed his interest in graphic expression. In 1962, Sordini and Verga joined Agostino Ferrari, Arturo Vermi and Ugo La Pietra, as well as the poet Alberto Lùcia to form the Gruppo del Cenobio in an attempt to combat the nihilistic and hypercritical trends in painting as well as the invasion of the American art culture with the success of Pop Art  and, in the following years, produced a series of personal and group exhibitions at the Galleria il Cenobio in Milan as well as at the Saletta del Premio del Fiorino in Florence, the Galleria L’Indice in Milan and the Galleria Cavallino in Venice. A major retrospective exhibition titled "Nel segno del segno" was held at Palazzo Stellina, Milan, in March 2013 to mark the fiftieth anniversary of the group's first exhibition.
