Tonino Casula (Seulo 1931) died in the early afternoon of today, after being hospitalized last week for a brain problem . He was then taken back to his home-studio in Piazza San Giacomo , in Cagliari, where, assisted to the last by his daughters, he was able to review his works , his screens, and the whole world illuminated by the much research which this great artist and art theorist has never stopped dedicating himself.

With a fighter, dissident, champion character , he began his adventure in the mid-1950s , when the '58 Group was formed in Cagliari, of which he belongs, then participating in the Transational Group (in 1965, with Leinardi, Ugo and Utzeri), the Democratic Culture Center (1966) and the Visual Arts Center (1971). Then with Gaetano Brundu , in the early 80s, they set up the activity of the international visual arts experimentation center of Villasimius. The focus of his research , carried out strenuously despite serious vision problems, has always been the complexity of visual perception , on which he wrote preparatory texts for Einaudi (as an enlightened teacher he was) such as "I mpara l'arte " (1977) and above all “ Between seeing and not seeing. A guide to problems of visual perception ” (1983).

From 2015 “ A feast for the eyes. The adventure of an artist who looked in the dark ” (Liguori editions). His works are in the Ugo Ugo collection of the Municipal Art Gallery of Cagliari but also free on the web, in the dozens and dozens of videos, with hilarious titles, to be watched possibly with 3D glasses, which transport you to a lysergic world, where every rule perception is subverted, decaying one after the other all the answers of meaning that come to us from empirical experience.
