He was born in Udine in 1929. He started painting at a very young age, winning immediately for his originality of language so that, just nineteen, he participated in the Venice Biennale in 1948. He enrolled at the Art School of Venice and then attended the studio of Emilio Vedova. In the early fifties he moved to Paris where he met with leading representatives of French culture. Travels a lot, stays in the United States, Mexico, Cuba, Venezuela, and from these explorations it will ensue that repertoire of signs that will draw then in subsequent years. In the second half of the sixties was the cycle that has made known to the public: that of the "Lager" consisting of precious paintings for mixtures and colors, so thick and material to be proposed already in the form of bas-reliefs. This is followed, in the seventies by, the "Muri antropomorfici", works in which archeology enters the painting directly. Since the early sixties Celiberti was also dedicated to sculpture, to produce large sculptures in bronze, steel and stone. Her creative curiosity led him to devote his artistic activity also to the original graphic, producing highly qualified engravings in black and white and silkscreen prints abstract, including color, very thick and textured. He has exhibited all over the world: Strasbourg, Brussels, Salzburg, Milan, Ferrara, London, London, Dusseldorf, Rome, Madrid, Paris, Genoa, Venice, Bologna, Trieste, Livorno and Chicago. Lives and works in Udine.
