The works os Richard Serra and Robert Smithson have a founding relationship with the public space of the contemporary megalopolis. By incorporating the notion of the specific time of material, their output expands conceptions of the artistic process and sets up a tension with architecture and the institutional space of art. As they propose to criticize institutional space and explore the word, the works set a play of similarities with the megalopolis, incorporating the rationale of its ethical, political and cultural space. I therefore investigate the relationship with the New York laboratory where Serra and Smithson engage in intense debate with their peers. This founding relationship was formed in and through the bustling Manhattan of the late 1960s and suburban areas of new Jersey. The decisive reference for Smithson s work was the entropy of the New Jersey suburb, from which infinite times and spaces are brought into his work. Serra s clash with the city is concrete and literal in nature. Working in the midst of the chaos and contemporary ruins of the city, he proposes a new relationship between the work, the spectator and the surroundings. There are elements in both artists that strive to broaden the concept of contemporary sculpture in a new relationship with the world.
