The Gorgona Group (named after the mythological creature of Gorgon), was a Croatian avant-garde art group which consisted of artists and art historians: Dimitrije Bašičević-Mangelos, Miljenko Horvat, Marijan Jevšovar, Julije Knifer, Ivan Kožarić, Matko Meštrović, Radoslav Putar, Đuro Seder, Josip Vaništa , operated along the lines of anti-art in Zagreb between 1959 and 1966. Beside individual works linked to traditional techniques, the members proposed different concepts and forms of artistic communication, ran a gallery and published the "anti-magazine" Gorgona. In each issue they featured one artist's work such as Dieter Roth or Julije Knifer. Works by the Gorgona Group are widely represented in a number of institutions in Croatia including, the Museum of Contemporary Art, Zagreb, the Filip Trade Collection and the Sudac Collection. Several years later, the group was disbanded, some of the members forming the Group of Six Artists.
