What is authenticity?
Authenticity describes the qualities owned by an original artwork. A reproduction of the same artwork does not have authenticity because it was not created by the original artist, under the same original circumstances. Authenticity of an original can become questioned once reproduced, lowering its value.
Orphism was an abstract style of painting influenced by cubism developed by Sonia and Robert Delaunay. French poet Guillaume Apollinaire created the term around 1912, which distinguishes the work of the Delaunay’s from cubism. Greek musician Orpheus inspired the term.
Action painting is the term which describes the physical act of painting as an essential part of creating an artwork. Action painting includes gestural use of painting tools, splashing and dripping paint, or dancing and moving while applying paint to a work of art.
Art Intervention is art which is intended to interact with an existing situation, structure, artwork, audience, or institution. Interventions became popular in the 1960s, as artists sought to effect change in political and social contexts. Artist-in-residence programs were inspired by this art movement.
