± Post-Minimalism – A loose art movement that formed in response to the cold, hard qualities of Minimalism. Post-Minimalist artists, including Eva Hesse, Robert Morris, Richard Serra, and Robert Smithson—who worked in a range of sub-genres, from Process art to Land art—favored more organic materials and forms than those used contemporaneously by their Minimalist peers. As a result, their work was often seen as invested with greater psychological, subjective, or erotic meaning.
± Process art – Art in which the process of its making is considered an integral aspect of the completed work and is typically left visible in some way. Jackson Pollock’s drip paintings are often considered the source of the post-war artistic interest in process, which informed the work of artists such as Richard Serra, Robert Morris, and Lynda Benglis.
± Land art – A genre of art making that began in the late 1960s in which art was made directly in the natural landscape or made out of elements of the natural landscape transported to a gallery or museum setting. Also called Earth art or Earthworks, Land art was pioneered by Walter de Maria, Robert Smithson, and Richard Long, among others.
