Bruce Nauman Born in 1941 in Fort Wayne (USA). Lives and works in Galisteo (USA). "Model for Trench and Four Buried Passages" (1977). At the end of the 1970s, Nauman's questioning as to the function of art took the form of skeletal volumes which are metaphors of communicational networks. Among these was Model for Trench and Four Buried Passages, a monumental "model" (at a scale of 1:2) of trenches and circular tunnels.
